DIY Semi Auto Air Rifle Made With QEV
In a previous video, I showed how to hook up and use a QEV for an air rifle or cannon. I used that QEV to make the air rifle shown in this video. The QEV has been matched with a three way solenoid valve. The three way solenoid valve allows the air reservoir to fill, and when it is triggered, it pilots the QEV, firing the air rifle. This setup is semi auto, each press of the trigger switch pilots the QEV. This air rifle has two barrels for it, a .22 Crosman rifled barrel 24 long, and a 36 long .25 steel tube barrel. The .22 barrel has a brass breech assembly with a bolt, allowing bolt action loading of .22 pellets. The .25 barrel has a similar brass breech for loading lead pellets, but also has a 20 round magazine for .25 steel BBs to allow semi auto use. Accuracy is good with the .22 rifled barrel. No problem hitting pop cans at 25 meters while hooked up to 120 psi shop air. The .25 barrel is not rifled but still shoots well enough for my 10 meter indoor range. This air rifle can also be hooked up to my high pressure air setup. I have fired it using 300 psi and it works reliably. Shop air at 120 psi is more convenient, and this air rifle works very well at 120 psi. It has a Tasco 3-9 power scope. The stock is made from steel electrical conduit tubing with a plywood butt. Power is provided by a lithium polymer 12 V battery inside the handgrip. The brass trigger presses a micro switch that switches the solenoid valve.

Homemade DIY .22 Air Rifle
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.

Homemade QEV multishot airgun (POWERFUL)! (16 joule, 656fps, 200m/s)
This is a project I've been working on for months. This is my homemade airgun which is (arguably) the best on YouTube. This gun shoots 6mm steel bb's at 200m/s (656fps). The video itself will explain some more details about it.
Most of the parts are bought on Aliexpress, so the build wasn't expensive.
If you have any questions about it, let me know in the comments.
