Homemade 36 caliber rifle or #000 shotgun pcp 400 psi 22 shot magazine Girandoni type

This is my 9mm QEV gun. I chose .360 #000 buckshot for the ammo. The Barrel is a 3/8 inch hydraulic brake seamless ss tube shrouded with a pvc pipe and tipped with a muzzle brake. The ss tubing is stiffened by wrapping 3 rubber tape bushings around the barrel to get it to fit snugly inside the pvc pipe and a slug of slow set JB weld is injected through 3 holes drilled just behind each bushing. This keeps the tubing from vibrating during the firing pressure surge thereby increasing accuracy. I also crowned all ends of the ss tubing with a bevel cutting bit to remove any burrs. The receiver is a 3/8" compression tee modified to accept a bolt and gravity fed ammo from the magazine through a 3/8" hole in the face of the compression nut on the leg of the Tee. The carbon steel bolt handle is held in the latched position by a small rare earth magnet. The magazine is attached to the side of the pvc barrel shroud with JB weld poured into the gap with tape on the bottom to creat a form for the jb to set. The gun is fitted with a red dot scope for daylight shooting and a laser sight for night time fun. The firing valve is a 3/8" alpha QEV. The trigger is a 1/8" push button valve. The accumulator tank is a 1" diameter by 12" long pipe shrouded with pvc. the plumbing from the A side of the QEV is covered with foam rubber to make a comfortable grip. The pressure supply ball valve has been omitted and replaced with a properly sized orifice to allow the gun to auto recharge at a rate slow enough to allow the 1/8" vent valve to trigger the QEV. This also minimizes moving parts, simplifies the gun and makes it easier to fabricate. You can drop this gun in the mud and clean out the barrel bolt and magazine tube by dry firing it with the magazine empty with end cap removed and the bolt in the open position. There are only 2 moving parts exposed to the elements and they both get a quick clean out of dust and sand with each shot. . You can see the only 2 moving parts in my video. The gun weighs a few ounces over 5 lbs. and can easily be held and shot like a pistol. Ok, i guess you can cut 12" off the barrel and 6" off the accumulator tank and voila' a pistolla. By keeping supply pressure on the pilot side of the QEV at all times during firing the safety of the QEV is "way mo betta"! It shoots faster than my .50 caliber because there is a few thousands of an inch clearance between the ball and barrel so the ball rides on a cushion of air and flys through the barrel without touching. I am now firing it with 400 psi regulated CO2 and it will shoot trough 3/4" yellow pine at 10 yards. Pics can be viewed on Spudfiles.com

can you pleas make a viedeo to the reloading mechanisem?please

[mpmrla]

@GeKnuT

My next video will be a mod of the single shot .50 caliber

it is a 28 shot gun with a better designed loading mechinism

while it is still basically the same type. There will be two

diagrams in this video showing how it is made.

@Aqlor all of the information is in the video description

also look at the other videos for more info

Well done, nice cannon! Im surprised I didn't see it on spudfiles...

@NorthernInventor the valve is a QEV, or Quick Exhaust Valve

@BTBpneumaticcustoms  it's in the pneumatic cannon showcase on spudfiles
