How are you going to get bb's in the barrel? My terminology isn't great, so do you mean manually loaded? because i've tried that after loosing my magazine, and it's as fiddley as a rude word begining in "F", so even a gravity fed magazine would probably be better (that could be added easy enough)

what do you mean "Co2 is easier to come by"? for co2 you need to pay for tanks or cylinders filling, air you just need a pump, don't you?

surely air is easier to get? all you need is a pump?

Alternatively, does anyone have experience with homemade CO2 pumps? theoretically it can be done. And do CO2 cylinders need regulating? probably a ...

Yeah, that was the original idea to electric, but I've got an AEG (TM), and it keeps breaking every time I have the ordacity to pull the trigger. can't really think of many advantages to making it electric, anyway (maybe more shots before needing a gas/battery change), but I liierally want to mow do...

A 20oz c02 tank filled with air (it is possible to fill it with air with the use of special fittings that can be bough from palmer's pursuit shop) will give you a short shooting time, not to mention pressure decreasing as you shoot. Can't you just have it regulated? The main issue here is being abl...

Hi, I'm new to the forum, and bbmg's, but not to spud guns or airsoft, and I'm starting out on the latest in a long line of projects. Most people here will have played CoD , I know I have far too much, and I have basically decided to build a Browning m1919 (bb)MG. Basically, I decided on this style ...
