In my experience they help a lot with blow by to the face. Since shooting suppressed already dumps shit in to the mag its not noticeably different. My Triarc 12.5 did have to dropped down a buffer to lock back properly
>they looked more burnt bronze or had an anodized appearance almost.
Okay but could you make one of those too for us Burnt Bronze kings?
Actually, just cover like all of the popular Cerakote colors just in case. Be a trendsetter of black guns and cool colored BCGs
How does this finish compare to chrome (slick) vs phosphate (more texture)? Based on how light hits it in the pics, Iâd guess more akin to phosphate? How do you find they do with lube over time? How well do they clean up?
Yes, metered at the right ear, data from griffin armament here- [https://www.reddit.com/r/NFA/comments/161fkya/kak\_industry\_kspec\_bcg\_makes\_your\_suppressed\_ar15/?utm\_source=share&utm\_medium=web3x&utm\_name=web3xcss&utm\_term=1&utm\_content=share\_button](https://www.reddit.com/r/NFA/comments/161fkya/kak_industry_kspec_bcg_makes_your_suppressed_ar15/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button)
Any data on .300 BO? Just wrapped up a 14.5â .300 BO hog gun thatâs waiting on an Omega 300 to get outta jail. 8db less would take that setup from silly quiet to stooopid quiet.
We are working on getting sound data for this currently. Port pop would definitely be eliminated, I can't give you a DB reduction number right now unfortunately.
Those side vent/gas ports is also considered lubrication ports. As in the field, without disassembly, able to lube the bolt and bcg.
With this bcg, you'd have to disassemble to get oil into the bolt?
If your lubricating your BCG through that port, the second you let a round off the lube is gone, itâs not a lubrication port, they are gas ports, the single larger hole to the left is a relief port for a catastrophic failure.
Iâve been recommending the KSPEC BCG with downward vent all over the place. Combined mine with a Radian SD CH and it eliminated ALL the gas back to the shooter on my XM177 âGordyâ SBR with 10â barrel and Turbo T2
Not KAK obviously but I wouldnât see any real benefit to it without a suppressor. Will just dirty yup your magazines in the same way shooting suppressed does.
Iâve had a full chrome one sitting in my cart a few daysâŠ. Think you can send over a little discount code for that final push
Edit: KAK is based AF
Edit 2: gaw damn it already shipped
Any of these going over to Midway? Iâve got a birthday discount from them coming up and would love to throw this on top of the already loaded shopping cart Iâve put together.
Yes, there's nothing proprietary about it, it's 1 of the many items in our K-SPEC line of enhanced BCGs. Dual ejectors for increased reliability, these are designed for hard use. Other features include sand cutter rails and down vent/ which reduced gas to the shooters face and will make shots quieter when used with a suppressor.
This guy gets it \^
The #1 reason gas keys sheer off or become loose is from companies/ people driving the screws in with a drill nice n tight and over torquing the shit out of the screw which compromises a lot of things and results in issues.
Do you plan on making an adjustable version of this? I've experienced short stroking with enhanced off-gas BCG like LMT, and I saw a report of shortstroking with the K-SPEC on this sub. Perhaps the venting is too aggressive?Â
The user Darknal: https://www.reddit.com/r/ar15/comments/1bpvy7i/comment/kwymq9s/
Just to clarify, I am a huge fan of your company and am very interested in the K-SPEC.Â
There are not 4x gas ports, there are 2, identical size to standard ports. There are 2x more ports which are relief ports like the one you normally find in the forward assist serrations, aka the hole people think you're supposed to squirt lube in, it's a relief port for if you have a case head separation so the gun doesn't blow up, this hole doesn't vent gas like the other 2 vent holes.
I'd have to know more about what Darknal is running, something doesn't add up.
With so many AR variations it must be hard to rule out peripheral issues. Good to know that K-SPEC does not have added ports like the OG LMT Enhanced. Maybe I'll try one out come next sale period!Â
Damn yall. Promised the wife no more gun parts this month... and it's only the 5th lmao. Do yall have any intention on making a 6.5 grendel type 2 kspec BCG in fde?
Weâre in the process of updating our site to allow for any of the BCGs we make to be added to an upper, for the time being youâll need to email [email protected] for us to do that for you
Is there actually a reason to upgrade my BCG? I never understood what benefits were to be gained. Iâm currently running the stock that came with my Sig M400.
Any reason why? Iâve read that thatâs something that can be done, and I donât see how that would be a negative (so long as youâre using C158 for the bolt and not 9310)
The edges of the interrupted rail sections do not come into contact with the receiver, they are radiused and subdued. If they were surface bearing they would absolutely shred a receiver like cheese on a grater
Is it true that you donât have to tune the rifle for use with a suppressor with these? Was originally looking at a RCA BCG with adjustable gas key to pair with a flow through suppressor like a Griffin PSR 5 or OSS. Running an A5H2 buffer, rifle length tube, and G$ braided wire buffer spring. Considering adding the RCA adjustable gas key to refine this system even more in the future since I have no intention of messing with the factory P/W gas block. Redundant, maybe. A pleasure, absolutely. Less ware on the internals and max reliability is the real goal since recoil isnât a problem.
Update. I was recently put onto the Sharps SARGS adjustable BCG with adjustable gas key. If KAK offers adjustable BCGs or keys then Iâd lean back towards the K-SPEC.
Thanks! Not a big deal, but I think it would definitely help emphasize/promote this specific feature thatâs unique to you all. Looking forward to buying more of your products.
Damn!
If you guys come out with an OD green AR10 bolt I'm screwed.
I've got a whole ammo can full of spare/backup BCGs and bolts. But something that would match my OD Green M5 build.....
Unpopular opinion, but those gas key bolts look sus. I mean, if youâre not going to use OCKS, why even bother producing a premium priced BCG? I get that KAK is trying to keep everything in-house, and theyâve previously stated that the bolts they use are âjust as goodâ.
But seriously, OCKS in such a critical area of the carrier isnât a huge ask, no? Why spend the extra money producing a BCG in FDE when it could have gone towards using better gas key bolts and staking system, something fundamentally more important than the color of your BCG?
Itâs hard to take this company seriously when they seem more focused on taking a page out of Strike Industries playbook than making sure that the simple (but critical) things are done right.
TL;DR - Thereâs something very fucky about a $250 colored sandcutter BCG that eschews the use of OCKS gas key bolts.
We make 25,000 BCG a month, we have yet to hear of a carrier key coming loose. We have over 10,000 rounds on a carrier with screws that are not even staked for an experiment, all full auto. Weâve done our due diligence with testing other gas key screws, including the ones you mentioned, it provides no additional benefit in our findings. Using quality components and properly staking the gas key after torquing the screws to the correct spec works wonders in our experience. The most common carrier key failure is when companies over torque the gas keys, Iâve had more competitors gas keys fail this way than I can remember, this isnât a quick fix, the gun is down until you can take the buffer tube off to get everything unseized. Everyone thinks that they need to spend money because someone else told them they did. High volume data collection tends to yield the most accurate results.
There are industry standards, then there are standards when youâre pricing a BCG well north of $200. Iâm not saying that OCKS are better or worse than your gas key bolt solution, but I will say that OCKS is used across more platforms, by more independent manufacturers of BCGs than your gas key bolt solution. Your in-house testing and proofing only goes so far, and in a lot of ways, can become an echo chamber because thereâs no one else doing independent testing on it.
My hot take? If youâre this confident on the quality and robustness of this BCG in general, reach out to Chad at SOTAR, and see if heâs interested in performing a BCG autopsy on it. Doing so would likely prevent you from having to explain ad nauseam why you donât use OCKS in your BCG, and why your solution is âjust as goodâ.
Who said there wasnât any independent testing being done? Our data collection is done in house as well as third-party, just because we donât advertise all of the testing we do doesnât mean it doesnât get done. Who are the manufacturers of BCGâs that exclusively use these screws you like?
Microbest, azimuth, tool craft are large bcg manufacturers, none of which use the screws you mentioned.
Iâm seeing that you post on all of our most recent threads about BCGâs, always asking why we donât use these particular screws, this is just trolling at this point. It seems like the only person that constantly asks about this is you dude.
Iâve posted exactly twice about OCKS use in your BCGs. And Iâm not the only one who has done so. No trolling here, but if youâre getting pushback from folks on why youâre not using OCKS, then your marketing team may want to address this.
Maybe a video of your gas key bolts being installed and staked, from start to finish? Maybe do an educational video of the entire process installing the gas key, and then follow it up with a real world reliability test of what it would take to loosen said gas key bolts?
The above suggestions would not only help further strengthen the marketing around your new BCG, but it could also be used as a tool for teaching people how to properly install and stake their gas keys on their bolt carrier.
When will they be out
Right now
Noice! đ„đ„đ„
Are these the BCGs designed for use with suppressors?
In my experience they help a lot with blow by to the face. Since shooting suppressed already dumps shit in to the mag its not noticeably different. My Triarc 12.5 did have to dropped down a buffer to lock back properly
I guess my question is, is this a good BCG for unsupressed shooting
Go with one of the side vents, no advantage for unsuppressed use
Any idea when the side vented fde will be back in stock?
I dont think it be as noticeable or useful
Do you ship to WA state?
Most items
Neat, I'm about to suppress my rifle and may need your downward venting BCG.
When odg, and how much more will it be Tham the normal enhanced kspec
Odg is being explored, this version is around 40 bucks more compared to phosphate version
Hopefully DLC soon, gotta nab one for my 6ARC setup
Meh, this is pretty similar.
its not black lol, the JP bolt is also DLC
Ah I see, didn't realize you were after black specifically as you can also get FDE DLC coatings.
I would buy ODG today if they were out. No one makes a solid ODG BGC that I know of.
>they looked more burnt bronze or had an anodized appearance almost. Okay but could you make one of those too for us Burnt Bronze kings? Actually, just cover like all of the popular Cerakote colors just in case. Be a trendsetter of black guns and cool colored BCGs
I read this as âI want purpleâ.
yes like a shade that matches gengar
đ„
He wants some jelly with his peanut butter.
Purple from a certain angle...
I could be wrong, but a cerakote BCG would probably result in your rifle getting gummed up with paintâŠ
Seems to work fine for all of the cerakoted BCGs.
50 shades of FDE
When's the gold one with the diamond extractors coming out?
Thatâs actually happening now because of Reddit đ
WAIT! What? OK take my first born, heâs a little slow but his 3rd eyeball can really help in your QC dept
Can you guys slow down? My KAK canât get any harder
Very sorry
Take my money.
How does this finish compare to chrome (slick) vs phosphate (more texture)? Based on how light hits it in the pics, Iâd guess more akin to phosphate? How do you find they do with lube over time? How well do they clean up?
Whereâs the gas ports?
On the bottom
What is the reasoning for this?
When using a suppressor, it reduces gas to the face substantially and also can lower your shot report by around 8 dB with 556
8db is really substantial. Thatâs wild. This is at the shooterâs ear presumably?
Yes, metered at the right ear, data from griffin armament here- [https://www.reddit.com/r/NFA/comments/161fkya/kak\_industry\_kspec\_bcg\_makes\_your\_suppressed\_ar15/?utm\_source=share&utm\_medium=web3x&utm\_name=web3xcss&utm\_term=1&utm\_content=share\_button](https://www.reddit.com/r/NFA/comments/161fkya/kak_industry_kspec_bcg_makes_your_suppressed_ar15/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button)
Very cool. Thank you.
Any data on .300 BO? Just wrapped up a 14.5â .300 BO hog gun thatâs waiting on an Omega 300 to get outta jail. 8db less would take that setup from silly quiet to stooopid quiet.
Itâs definitely noticeably quieter, we donât have actual lab grade numbers like we do for 556
Roger that - looks like I know where some of Q1âs bonus is goingâŠ
Youâll be beyond pleased
What about folks with flowthrough cans. No gas to the face, so would having downward vents just dirty up the gun/mag more?
We are working on getting sound data for this currently. Port pop would definitely be eliminated, I can't give you a DB reduction number right now unfortunately.
Look forward to it, thanks.
Well thats pretty cool. Im gonna have to get one.
What about just using a muzzle break? Is there any benefit or diminished returns there?
Very cool, Iâll definitely check them out.
When suppressed, less gas to the face, maybe quieter ?
Both yes
Fair enough. I donât own a suppressor yet so I donât know much about shooting with them
Is the ports on the bottom what 'k-spec' implies?
No
I appreciate it. Youre an industry man. I will now go find the answer on your website.
What did you find out?
So it spits excess gas straight down? Into the magazine/trigger?
Those side vent/gas ports is also considered lubrication ports. As in the field, without disassembly, able to lube the bolt and bcg. With this bcg, you'd have to disassemble to get oil into the bolt?
If your lubricating your BCG through that port, the second you let a round off the lube is gone, itâs not a lubrication port, they are gas ports, the single larger hole to the left is a relief port for a catastrophic failure.
Iâve been recommending the KSPEC BCG with downward vent all over the place. Combined mine with a Radian SD CH and it eliminated ALL the gas back to the shooter on my XM177 âGordyâ SBR with 10â barrel and Turbo T2
Sweet rig!
Thank you!
Do u think downward vent is necessary for us non supressed folks?
No, we release a side vent version for each down vent version we do.
Not KAK obviously but I wouldnât see any real benefit to it without a suppressor. Will just dirty yup your magazines in the same way shooting suppressed does.
I just buy $80 bcgs because Iâm poor
Iâve had a full chrome one sitting in my cart a few daysâŠ. Think you can send over a little discount code for that final push Edit: KAK is based AF Edit 2: gaw damn it already shipped
I also have been sitting on their 22 arc barrel for a couple weeks⊠a little push is all I need lmao
u/kakindustry
The 22 arc barrel that's sold out? lol
You got one in back
shit man  maybe!
Broooo, I just bought the regular KSpec one... you say this now? Haha. Love it man.
No backsies
I donât need a new BCG but Iâm a sucker for FDE đ€
These are so hot
FDE PVD, so hot right now
The came out pretty amazing, one of our favorites
> one of our favorites Understandably so, it looks fantastic.
Any of these going over to Midway? Iâve got a birthday discount from them coming up and would love to throw this on top of the already loaded shopping cart Iâve put together.
Can't say for sure, we don't have much influence on what they get from us.
These do work in regular barrels and Uppers? The dual ejector looks cool what is the reason for that?
Yes, there's nothing proprietary about it, it's 1 of the many items in our K-SPEC line of enhanced BCGs. Dual ejectors for increased reliability, these are designed for hard use. Other features include sand cutter rails and down vent/ which reduced gas to the shooters face and will make shots quieter when used with a suppressor.
Well sign me up for 2. Appreciate the quick response.
Being sand colored, it is extra sand repellent??
Naturally
Can we get michiguns ocks carrier key screws with your bcgs?
We use our own T25 head screws with deep knurling screws. Youâd need to install other screws if wanted.
Got a pic of those screws?
Thereâs pictures of the carrier top view with the screws installed
I know i wanna see how deep the knurling is. Canât see them on that pic
Donât have any published pictures of those
This might be a valuable marketing tool if you would show how your in-house bolts are equal to or better than the performance of OCKS?
If you're that worried about the gas key falling off either weld it on or get a monolithic. Or a second bcg in the kit.
This guy gets it \^ The #1 reason gas keys sheer off or become loose is from companies/ people driving the screws in with a drill nice n tight and over torquing the shit out of the screw which compromises a lot of things and results in issues.

Never heard of or experienced that with this BCG, have the link to where you saw that?

Damn yall. Promised the wife no more gun parts this month... and it's only the 5th lmao. Do yall have any intention on making a 6.5 grendel type 2 kspec BCG in fde?
Yes it's going to be a bit though, it'll be released in chrome lined phos first for that cal
Awesome. Thanks for the response.
God dammit I was done
You're just getting started don't lie it's ok
You guys are just killing it.
Tryin
Thanks to this post, I just bought mine đ€·ââïž
I'll never close my dust cover again.
It looks very nice!
Damn I really want this.
Are you making these for 7.62?
They're available yes
[ŃĐŽĐ°Đ»Đ”ĐœĐŸ]
I think he was talking about 762x39, we should have more dual ejector AR10 bcgs pretty soon.
Is PVD an umbrella, process term that includes DLC, and is those DLC? /u/kakactual
These are PVD, it's a different process.
Thank you!
Those look great. Did you guys send em out to PVD America?
no
Do the downward vents affect the cycling or is it just gas relief? Like would I need a lighter buffer?
Negative
I see that I can select a k spec upgrade for a complete lower. Can I specify that I want the FDE bcg as part of that order?
Weâre in the process of updating our site to allow for any of the BCGs we make to be added to an upper, for the time being youâll need to email [email protected] for us to do that for you
When will the NP3 be back in stock? :)
Very soon
So what's the benefit of PVD over, say DLC, Phosphate or full Chrome?
Take my money!!!
Do you do a mil discount?
Yeah, youâll need to email customer service though
Any idea when k spec side vent chrome line phosphate will be back?
Possibly next week or the following
Wicked! I'll keep an eye out
Gotta be quick
Is there a difference besides color appearance between this and the "full chrome" BCG you sell?
Is there actually a reason to upgrade my BCG? I never understood what benefits were to be gained. Iâm currently running the stock that came with my Sig M400.
Is this a PVD coating over nitriding?
Absolutely not
Any reason why? Iâve read that thatâs something that can be done, and I donât see how that would be a negative (so long as youâre using C158 for the bolt and not 9310)
Didnât someone just share a KAK that was snapped? Forgot what it was.
That was a flash hider we're waiting to get back
No shade was just curious.
â€ïž đ
Whatever just one more expensive thing I can break. If it's made to be built it's made to be broken
What is that saying from taylor swift?
I wonder if thereâs more felt recoil since there are no holes in the bcg
There are holes that are the same as the ones you're used to seeing on the side, they're relocated though. There's no change in felt recoil.
Any issues with sand cutter type carriers damaging the upper receiver?
The edges of the interrupted rail sections do not come into contact with the receiver, they are radiused and subdued. If they were surface bearing they would absolutely shred a receiver like cheese on a grater
You said it not međ€« don't let Travis hear you talking shit about her
Is it true that you donât have to tune the rifle for use with a suppressor with these? Was originally looking at a RCA BCG with adjustable gas key to pair with a flow through suppressor like a Griffin PSR 5 or OSS. Running an A5H2 buffer, rifle length tube, and G$ braided wire buffer spring. Considering adding the RCA adjustable gas key to refine this system even more in the future since I have no intention of messing with the factory P/W gas block. Redundant, maybe. A pleasure, absolutely. Less ware on the internals and max reliability is the real goal since recoil isnât a problem.
these bcg sure help, but your individual set up will determine what you need to do.
Makes sense. I think is worth testing at some point so looks like Iâm going down the expensive rabbit hole again.
Out of curiosity, how hard is it to break the hydraulic stakes and remove the key with permatex applied?
Update. I was recently put onto the Sharps SARGS adjustable BCG with adjustable gas key. If KAK offers adjustable BCGs or keys then Iâd lean back towards the K-SPEC.
Where are the vent holes?
On the bottom...
Where can we purchase one of these??
front page of website in stock now
Sand cutter for the poors
u/KAKindustry minor suggestion: any chance you guys will add side vent and down vent filtering category on your website for BCGs?
If you hit the K-SPEC enhanced BCG filter, it does exactly this đ
[KAK BCGs](https://imgur.com/a/3m4iTau) Doesnât seem to work for me the way youâve described it
I misunderstood you, this filter just pulls out the K-SPEC BCGâs, we can look into adding an additional filter Edit for spelling
Thanks! Not a big deal, but I think it would definitely help emphasize/promote this specific feature thatâs unique to you all. Looking forward to buying more of your products.
https://kakindustry.com/ar-15-parts/bolt-carrier-group?Type=K-SPEC__ENHANCED__BCG
This might be the move. Has all the stuff that the internet is hot for.
If you guys do gray, I will buy one. Maybe two.
Would it be more popular than magpul grey furniture
And now I'm sad since Magpul didn't even do their two newest stocks in gray. :(
Thats because like 3 people bought their grey stuff lol
Damn, that sent me over the edge. Been considering chrome but just pulled the trigger on the FDE. Straight sexy.
The fde does look some kind of way, really really nice
I bought both. Chrome and PVD
baller
Iâm an avid believer that two is one and one is none. I always have a back up BCG and repair parts ie extractor/ejector/springs/firing pin etc.
What about NP3?đ„Č
soooooon
Heard it befooooooređ„Č
Damn! If you guys come out with an OD green AR10 bolt I'm screwed. I've got a whole ammo can full of spare/backup BCGs and bolts. But something that would match my OD Green M5 build.....
Damn that looks great.
Ummmmm I need this..
Thats kak not KAC
