well the first thing i'd to say is ouch..... i shot my self in the leg and it hurts alot left a little bruise infact this is resonably powerful ive worked it to be around 360fps which id say is good for a home made springer. good adition to my collection lol


SPECS:
chamber: modified pneumatic door opener
piston: modified pneumatic door closer piston (got two of the o-ring holders and welded an extra washer to hold spring and trigger)
power: 360fps or so
barrel length: going to be 35cm with balloon breecher breech.

PS-Yes I'm aware someone has already posted this link but I can't remember who or where, and I know that it won't be the most accurate gauge of power ever but its better than guessing...I think. Anywhos have fun.

That looks a bit ghetto, but if it can shoot an airsoft pellet 400 fps, I'm not complaining. I would say it could easily get 400 fps, because those door closing mechanisms are very strong, and if you're using it the way I think you are, then you could easily hit 400 fps with that thing.

yeah ive got to get a longer barrel for it yet and then ill test the fps and ive also modified the door closer i took it apart and put two oring holders on it so it got even more pressure and welded a washer onto the shaft so it take the spring pressure off of the plastic oring holders and with my balloon breecher idea which keeps the ammo held tight in the barrell and allows a little bit of pressure to build up behind it with some shots you can hear a bang lol
