the MJV0-3 is your best bet for a homemade airgun

I typically use two 12 rounders and an 18 on a belt rig with a longshot or stryfe, it works well because our rounds are short in Australia, but i do carry a hammer shot with loose darts in a dump pouch just in case. i did have a good idea for either a gravity feeding mag on top of a blaster which you can just put darts in the top, and i also had an idea for a longshot with a hopper, you could use stephans and have a 6 dart capacity with a pretty short hopper, then instead of reloading through a ball valve you could just pull the hopper out and exchange it for another one carried on a belt. 

have a look on hobbyking, they have multiple chargers, choose one that will suit you. As for micro switches the blaster tech ones are good http://www.blasterte...94_3776362.aspxand so are the OMRON switches everyone uses however i'm not sure where they come from

couldnt you just move the handle, and by extension the trigger back? or do a longshot style pusher arm on the trigger?

alright thanks meaker, i will probably use that 7 shot one or the 8 shot one and see how i go, if dart fit is a huge issue i can probably replace the barrels with brass
