This gas cylinder is designed and made by me.I call it as "Monster Gas Cylinder for Sniper Rifle(MGC4SR)"
Let me explain what is defferent with conventional gas cylinder made by CA and KIC.
Not likely other gas cylinder,this MGC use external power source for stable velocity(FPS).This is important factor for better accuracy.Valve system use balanced valve method,so it need smaller impact to open valve it means you do not need to cock bolt hard.
FPS is fully adjustable and no need to disassmble it to exchange spring for adjustment like spring powered system.One of problem using hard spring to make higher FPS is,you need muscle to pull bolt hard.And you also need to spend more bucks on upgrading trigger,piston,cylinderhead,spring guide.
This is very good system for game and shooting application.
I appreciate it if you guys comment what you think of this.
