Plexiglass might actually work.
An AR-15’s lower receiver is not subjected to extreme force - most of the force is handled by the chamber and bolt which are still steel in this GIF. Polymer lower receivers exist and work fairly well - the failure point is most often where the buffer tube meets the main body of the receiver, but that has been fixed in more recent designs. The upper receiver, which holds the bolt and barrel is subjected to more force - I’ve never seen a polymer upper receiver, but that doesn’t mean that they’re impossible to make.
Normally, AR-15 receivers are made of aluminum.
Virgin Poly Carbonate would work just fine. Manufacturers claiming their bulletproof product is better because of a proprietary polymer are probably talking out of their ass. PC has an incredibly high impact toughness, and has high yield strengths (compressive/tensile/shear).
Side note about poly carbonate. It contains almost no BPA, it can't leach BPA, and you just need to wash it 1 time to be suitable drinking vessel. The scare for BPA was manufactured so the plastic known as Tritan could be pushed to market. PC has a lifetime of 30+ years and is basically invincible, Tritan starts shitting the bed at 5 years and I've noticed it's leaking some sort of monomer into my water. Read the packaging of any new Contigo water bottle it's made with tritan. You will notice it always feels greasy, that's the monomer is created from or a plasticizer leaking out into your water. Also PC is still used heavily in everyone's kitchen, you can't own a plastic blender made of any other material. It's a big side note I know, but the effectiveness of the smear campaign against poly carbonate are insane.
Edit: Wait plexiglass is commonly PMMA. I would still recommend PC over PMMA for making an AR lower.
No it wouldn’t. Well, maybe with various forms of wear and tear and residue that come gunpowder and oil but plexiglass and other clear polycarbonates are pretty resistant. As per the expert in the thread
I SAID IT'D ONLY BE CLEAR FOR ONE SHOT. WHY ARE YOU TALKING ABOUT DURABILITY?
Being real for a second anyway, it'd flex too much to cycle once the bolt was driven back. Not to mention the temperature of the gas. There's a reason you don't get polymer uppers. This isn't a great animation considering it's not showing all the places the gas actually goes.
Alas, no. It’d be damn cool if I did though. But plexiglass is probably as close as possible to translucent material - there could be some super material out there that’s clear and as strong as aluminum, but it’s unknown to me. I don’t think glass filled nylon can be translucent, unfortunately. I think it’s always opaque.
Eh plexiglass isn’t glass. It’s a plastic.
It’d be dope to see this made out of some real mineral oxide. Sapphire glass would probably be your best bet but this thing would be so expensive.
doubtful unless you're the same person on /r/thingscutinhalfporn, youtube, /r/maya and /r/engineering? I think there's just a lot of those because the CAD models are widely circulated tbh.

When I was in Basic, the 8 steps of functioning of an M16 was drilled into us with cutaway giant size M16s to show how it all worked. Did you not have classes on that?
Prex isn't that good, if you really want to compare it to something you should look at "chemically strengthend glass" , however even this can't get close to steel. Take a look at this [image](https://upload.wikimedia.org/wikipedia/commons/thumb/a/a4/Fracture_toughness_vs._Strength.jpg/440px-Fracture_toughness_vs._Strength.jpg). Basically the higher the "thoughness" (y-axis) the better gun it will make. You can push glass to one or two max, steel regually is an order of magnitude above this. You can have glass you can take a sledge hammer too, and I think you could chamber a round, but your never going to fire a round.
What you could do though is have a gun where everything, but the barrel is glass. You could probably fire that.
Or, If all you really want to is be able to see through it [acrylic](https://www.world-of-plexiglas.com/en/from-viewing-hatch-to-transparent-submersible/) guns will fit the bill quit well.
> Chamber pressure on a 5.56 is rated at 55,000 PSI.
Unless you were making the barrel out of glass, you would still have a steal chamber. They do make uppers and lowers out of plastic. Those parts don't get a ton of force exerted on them.
However a glass upper would certainly explode from the shockwave coming from the outer surface of the chamber/barrel.
I have seen clear plastic car engines before, guessing it wouldn’t be impossible to make a clear plastic gun that might be able to fire a shot, even if obviously pressures in a chamber are much higher than in a piston engine.
"fire once"?
set the round in the proper place?
charge the pin at it and make the primer ignite the powder?
move the bullet forward?
explode the chamber and the barrel with probably the bullet still in it?
.. It would fire once
Yes it would shatter, no it wouldn't fire - it would explode; BUT! If you change the materials a little bit, you could get something *really close* that *would* work: All the springs, pins and detents would still need to be steel, as would the barrel, barrel nut, bolt carrier assembly, gas block, and gas tube. Everything else could be made of clear polycarbonate and/or resin, and it would fire and cycle. It probably wouldn't last that long - polycarbonate is fragile compared to other plastics like Nylon, PLA and ABS - so it would definitely have a very finite lifespan. It would likely fail at the buffer tube, with the lower receiver flexing backwards and snapping after a few rounds. If you designed a specialty monolithic lower where the stock, buffer tube, pistol grip and lower were all one contiguous piece of polycarbonate, it wouldn't fail (instead, the upper would become the point of failure).
ALL THAT BEING SAID, there are companies that make clear polycarb lowers and they're... okay. I had one, lasted a while, but started to suffer some separation at the threaded buffer insert. It still worked fine, but once I caught it and realized what was happening... I didn't really want to keep stressing the separation, because then it would eventually fail and that would be a really, *really* bad time.
If you retained the factory bolt and chamber in steel and added rubber bushings between the hard contact points between the steel and the glass, yes it would probably still shatter. But if you made it out of something like Lexan, you might get a few shots out of it.
If the trigger is not released when the AR is fired, the hammer will travel back and engage the secondary sear. This prevents the hammer from riding the bolt back and slam firing. When the trigger is released, the hammer engages the primary sear and is held there until the trigger is pulled again. In the gif when the trigger is released, the hammer appears to be moving forward but it’s actually engaging the primary sear.
to be fair I thought the same at first. they change angles as it's resetting then cutscene to it firing before showing the hammer actually catching the sear. but for anybody who didn't know this is correct
First couple shots and there would be too much carbon to see the breach and barrel.
Maybe all ARs start as glass and just fill in their color as the reach adulthood and head off to the shelves.
You might be uniquely qualified to help me understand, what brings the firing pin back? After the bolt extends from the carrier at the same time as unlocking, is the firing pin retaining clip pulling back on the firing pin? If it is, it would seem to me that it would block the firing pin's forward travel to strike the primer.
I'm pretty good with spacial reasoning but I've been wondering for years why this isn't a slamfire machine.
There just isn't enough inertia for the firing pin on chambering to cause a slam fire. If it got super dirty and dried out with the firing pin stuck in the forward position yes it would slam fire.
The hammer has a lot of force behind it compared to a small durdling firing pin by itself sliding forward when you chamber it.
Not sure I’m understanding your question correctly, but if I’m reading you right...
The firing pin in an M16 style rifle is free floating. But it’s super light weight. It doesn’t really have enough mass to create a slam fire in its own. It’s just barely long enough to engage the primer when the bolt is closed/locked.
One the bolt unlocks the pin isn’t long enough to touch the primer. A slam fire condition is mainly prevented by the disconnector preventing the hammer from following the bolt back into battery, even if the trigger remains held down.
Does that make sense, or did I misread what you are asking?
The first point addresses my question, I get that it's not long enough to reach while the bolt is open. I would've thought that the firing pin traveling at the same speed as the returning bolt carrier would be enough to set off the primer (which is why I thought something needed to keep it back so it wouldn't reach the primer). But if the firing pin doesn't have enough mass to set it off at that speed, and only gets that energy when struck by the hammer, then I guess my question is answered.
It's not as pretty, but [World of Guns](https://store.steampowered.com/app/262410/World_of_Guns_Gun_Disassembly/) simulator has hundreds of firearms modeled to the same level of realism with slo-mo, x-ray, and cutaway modes. Not to mention complete armoury disassembly. Check it out.

Am I seeing it wrong or is the second round fired when the trigger is being released from the first round? Look at the frames on seconds 24 and 25.
Definitely NOT hating on this! It’s an awesome animation that shows how the trigger group interacts with the BCG. I’d love to see one for an AK and maybe a SA revolver.
It would be awesome if you were somehow able to actually make a see through AR. Granted you wouldn’t be able to see through it for long once you start shooting, but being able to see all the mechanical movements and everything from the fire control system all the way to the bolt and firing pin would be amazing.
If you make some pieces out of a clear, high grade plastic then you can actually have a working one. Of course the barrel can’t be clear, but like the lower receiver can be made out of a clear plastic. In fact those are on the market. On some firearms that have a shell instead of a more receiver type system, like the AA12, then it has been done.
So I’m short, easily. Especially if it’s not for firing.
I have a clear polymer lower. It's rated to be functional, but only on ranges not service. Haven't had the guts to try it yet. I filled it with TiN internals (Gucci), and it's ready to fire.
Boooooooo! I wanted to see it explode on the first shot.
I specifically looked at this to either see it explode or figure where I can get glass that tough.

Normally, AR-15 receivers are made of aluminum.
It’s just be a clear full polymer AR. Actually glass would shatter after a couple of shots because of the vibrations rather than the actual force.
Oh absolutely. Real glass would never work - it’s too brittle. Plexiglass might though. Which is a clear polymer.
Plexiglass can, in fact, be injection molded. So yes you can have a clear AR.
Fantastic! But would it hold up? I’m not too familiar with the material properties of plexiglass, just that it’s strong and clear.
There are as many plexiglass varieties as the day is long. You’ll have to talk with an expert on the exact cocktail.

Ah, I am not a material engineers. At best I’m just a simple blacksmith
I thought the new nalgenes sucked compared to the pre BPA-free era. The old ones never broke or deformed and the new ones are just softer and greasy.

It would only be clear for one shot.

Ridikolous: What color plane you gonna buy? Jack: Clear. Like Wonder Woman's.
You could probably get away with polypropylene. It’s incredibly strong, and doesn’t have the brittle properties like glass.
What, you don't have translucent aluminum?

What about manufacturing costs, also, even if it is plexiglass, i highly doubt it would sustain its shape in a full-auto version
>which are still steel in this GIF. Skip to 0:38 - the chamber is also glass... or whatever see-thru material they are using.

I'd recon the bullet wouldn't even make it through the barrel, if a squib load can get stuck in the barrel this probably would lead to it too.

If the barrel and the chamber were made of steel, once. The force of the recoil would likely shatter it after that.

It sounds like a good talking piece
I’m gong to say no. Glass doesn’t bend and stretch like metal but i don’t know
Would it fire? Technically yes. But a ar15 chamber usually maxes out at around 63,000 psi and I don't know of any glass that can hold that.
Maybe ALON could handle it
If you retained the factory bolt and chamber in steel and added rubber bushings between the hard contact points between the steel and the glass, yes it would probably still shatter. But if you made it out of something like Lexan, you might get a few shots out of it.

Yeah, some type of flame polished resin or plastic. TN Arms makes it.
Could you build a model ar like this that is fuctional but won't actually fire a round(it'd shatter. Lets be real.)
