Evanix Renegade Carbine

Dude, the air tubes on these guns are tested to at least 5000 psi of constant pressure. They are also tested for burst pressure and that is probably between 10000 and 20000 psi. So no worries about the "fragile" tank. It will do quite well if you only fill it to manufacturers specs of 3000 psi and keep petroleum based products away from the inside of the gun. As to the pellet "problem", I have never had one. Some fit looser than others, but never found any would come lose and jam the gun. Of course I take an extra step. I tap the magazine repeatedly on a soft cloth placed on a hard surface with the skirt side down to "seat" the pellets. The bottom part of the magazine is smaller than the top so you must put the pellets in from the top skirt down. Yeah, if you shove em in heads first from the bottom, a LOT of them will come loose and cause the gun to jam. Another more elegant solution is take a brass rod just a few thousandths of an inch smaller than the cylinder hole, put a collar on it with a set screw so you can adjust it for pellet length, the use that adjusted properly to shove the pellets down a bit so they are held firmly. You don't need to shove em in very far. Maybe .005" to get them to hold. Oh, and don't preload cylinders and put em in shirt or pants pocket and expect them to have pellets in them. Most will be in your pocket!!

for a 3000 psi gun you need a 4500 psi scuba tank find a scuba filling station that can fill close to that will cost about 8 to ten dollars to fill and you will get 50 or so fills ..happy SAFE shooting..
