nerf gun airtech 2000 and 3000 mod!
alright... so i hooked a soda bottle up to a nerf airtech 2000 (when i get the stuff for the 3000 i will do that one too) and so now i have a big resivoir and i have a way of hooking it up to a bike pump so i can pump it up to a reasonable pressure and run around and cause pain without tired arms. but the guns pump still works (and gets it up to about 40 psi after 2 minutes of pumping) you use a 4 way coupler WITH HOSE CLAMPS! and use tubing rated for pressure!
you have a schrader valve (or similar) and plug the pump on the 4 way along with the out line. (this was done on a 2000, the 3000 may or may not work) DONT HOLD DOWN THE TRIGGER! if you do then much of the pressure will be lost. now you can shoot easily and not be found out by pumping noises) im sorry i dont have a diagram. so when your done... the soda bottle (2 litre is the best! it lasts longer), schader valve, output, and input from the onboard pump should all be on the 4 way coupler and be hose clamped (if not the hoses will fly off and youll hear a loud hiss and be angry) the 2 litre bottle can be consealed in your backpack or be heald under your armpit, glued or taped to the gun, whatever!
