I made this air rifle recently and decided to do a video on it since it is quite accurate and reliable. It is a single shot bolt action .22 cal. The barrel is a 24" Crosman rifled .22 air rifle barrel purchased online. The air reservoir is 18" long with an ID of 1.125". The valve is a QEV, piloted by a solenoid valve. The solenoid is operated by a 555 timer circuit and mosfet. Power is supplied by two 12 V model aircraft lipo batteries, giving 24 V for the solenoid and 12 V for the driver circuit. The trigger is a small push button switch. There are no iron sights, the scope is a Tasco 3-9x - 40mm. This rifle is run off the shop air line at 125 psi. This QEV does not like pressure over 150 psi, so to get higher velocities, the QEV would need to be swapped out. At 125 psi, this rifle shoots at 420 to 450 or so fps using a 17.2 gn pointed lead pellet. This rifle is accurate, I have tested it successfully at 25 meters as well.
