pumatic airsoft gun help ? Answered
Ok so heres my situation. About 6 months ago I made my own pneumatic airlift sniper but even though I could get about 80 lbs of pressure stored up before I pulled my trigger my sniper only shot as far as my 300 fps gun. My question is why cuz I had a lot more force in my pneumatic sniper then my other gun and it doesn't seem to matter. My sniper was made of a metal nipple about 9 inches long and 2 inches in diameter. I then put a cap on one end and a reducing coupler on the other. I drilled a hole in the cap and inserted a valve that allowed me to attach the chamber to a bike pump. On the end with the reducer I then added a ball valve that worked as my trigger. After the ball valve was another reducing coupler that brought the size down from an inch to 1/2 an inch. Into this coupler I screwed a break line about 50 cm long(sorry about the unit change I don't remeber its length in inches) and it fit the bb very nicely. I also added a little contraption I made from paper clips that allowed the gun to be tired downward without the bb falling out. However I don't believe this was the problem as I fired the gun when their was just a wire across the back of my breakline ,to keep the bb from falling into the gun ,and the distance seemed the same.
I made sure every connection before the ball valve was sealed well except that the gun did leak at a rate of 20 lbs for minute because of a bad connection with the valve that connected with the bike pump. If you need more info just say so in the comments but I don't have the gun with me right now so all i have to go off of is my memory. Thanks for your help I really appreciate it. : )
