Newest Buttstock setup

Last week, I finished a non collapsible buttstock from a chunk of 4130 tube I had, that used my old Stealth valve, today I
finished another that used a new valve I made to fit. It’s pretty much a big valve that’s good with CO2.. Made another tube, and silver soldered a block on it to make the stock adjustable. Here’s pics. I am not sure of the velocity or shot count yet, but based on other cylinders I made, this should get about 25-30 shots.
I had thought about making a few and selling them, but it’s way too much work!
