I recently went to a Kmart and bought an "Ultimate Dual Action Pump" to use in a homeade i have been designing. But when i got home i realized that it didn't work, so i decided that before i returned it i would have a look inside and thats where i found a check valve that would work perfectly for an air tank system. It could fit on a penny and does its job really well. So if theres anyone out there in need of a small check valve stop by Kmart and pick one of these up. The whole pump set was 4$, and in my eyes its worth it.

I recently took all of the air restrictors out of my LS and added a stronger spring and it works great; with the darts that it came with. I can't get any stephans to fire further than two feet and all other Nerf darts always get jammed in the gun. Is there anyone who knows what might be the problem? Thanks.

I recently bought a few SSPB's and tried both of the mods in the directory but both times i got a decrease in range. They look exactly as the ones in the picture but they don't work at all. Can someone try and help me out please? Thanks.

Alright so I always liked the way that Nerfer34's PPK NF looked but i think that the barrel sticking out takes away from the PPK look. Would it be possible to take out all of the internals of a NF and just put an AT2K in it using where the plunger tube used to be as the barrel instead? I think this would look much more like a real PPK and also be much more balanced then the version with a 6" barrel.

Oh and just for the record, the reason that I posted this question instead of trying it out is because i don't have an AT2k to try it out with, but if anyone would like to donate one i would be glad to try it out.

I've been working on a semi-automatic gun and everything has been going well except for my valve. I have a perfectly air tight tank that can hold up to 70 PSI from 25 - 30 pumps from a bicycle pump. I originally tried to use Dr. Nerf's valve design, but I've found it almost impossible to get the seals airtight. Does anybody have any ideas as how in just one pull of a trigger i could release the air from a firing tank and keep any more air from flooding the firing tank while the trigger is being depressed?

And while im asking, any ideas for a trigger activated breech?
