Homemade airbow bullpup

Stock is made from 1/4in plywood with nylon spacers. Reservoir is made from 1/2in sch 80 steel pipe. The valve is a 12v solenoid valve. Trigger is a momentary toggle switch. Barrel is made from a carbon fiber arrow with a OD slightly smaller than the ID of the arrows I'm shooting. The barrel shroud is a AR-15 17in free floating hand guard from wish. I pressurize it to 1100psi using a cheap pcp hand pump from wish. Not sure how many FPS it shoots because I don't have a chronograph but will pass through a 1x6 pine board from about 15 yards.

Here is a video shooting it. I was only running 800 psi for this shot. [youtube][/youtube]

Welcome to the forum and great job!

I like the addition of the rail, it just needs lick of black paint.

What valve are you using exactly? That's quite a lot of pressure.

I'll have to find the paperwork on it but it's rated to 75bar.

Thanks hectmarr
