that was my point you cant just go to walmart and buy a paintball gun they cost 300$ for a cheapo one

i made one of those pvc ones where you pump the air into the bottle and it fires one at a time but nothing half worthy to play a fast game of paintball in my backyard

None but i have made a pbmarker from pvc pipe but thats and unrealistic venture for a bakyard skirmish i found this http://www.zdspb.com/media/tech/animations/automag3.gif need help recreating it

the reason i dont want to buy an cheapo paintball gun is because my friend had one and it exploded no jokes but i want a semi auto i dont care if its compressed air or c02 just need some ideas

im looking to do some backyard paintball i dont want to buy a gun so any ideas would be great thanks
