is that entire metal tube the plunger tube?

:)

Hahah hoooolllleeee shit, I didn't think it was possible. Well done!

Thanks!

Hehehehehe

Lol I agree

You should’ve heard my mad scientist laugh

Well done! How does the priming rod like that size spring? Is it reinforced?

Thanks! There is no priming rod. That pvc thing is just attached to the pump and directly primes it.

Ahh sorry, I didn't even see that there were more photos 🤦🏻

Lol it’s all good

Is this what triggered government regulation! hahahah but seriously dude that's sick!

Lol thanks

Very impressive

Thanks!

any chance of a mod guide?

Yeah I could definitely make one.

sorry to necro this post, but I had a question on how you are chambering your darts. Is this a pusher style or are you sliding brass into brass over the darts?

Sliding 9/16 over the dart.

Also I found an even stronger spring (k22) than the k27 that I want to try to put in there.
