(Update) My Second Spud/Airgun (M4 Carbine style)

Unread postAuthor: Sergeant Dotson » Mon Jan 21, 2008 6:54 pm

This is the second and most proud airgun I have made. The air chamber is made of galvanized steel and the interchangable barrels are PVC. I used a Orbit brand sprinkler valve and a precision air trigger. I charge this bad boy up to 120 PSI which is enough power to shoot a jellybean through several pieces of cardboard. Please leave comments (positive preferrably but if it's an an improvment, go ahead and tell me) ,also please vote in my poll, and I hope you enjoy these pictures  :wink: !

Cmon, with a setup easily capable of 150+ (limited by the sprinkler valve), I wanna see some nice damage pics. Very nice. are the barrels half and one inch?

By the way, how much PSI do you think the valve can handle? :o

Those valves are typically rated to 120 psi, so go above at your own risk. However, if you replaced that valve with, say, a qev, you could take it to 150 +. Nice gun, by the way! Good job on that sprinkler valve! Point of interest: blowguns have been tested past 300 psi, so you shouldn't have to worry about it if you implement it in a future high pressure gun.

Hey, thanks a lot man, instead of pressuring to 80PSI, I will probably pressurize it to 100-110PSI. :P

Oh, it looked a little bit bigger in the picture. I really like this gun, it's simple, but I'll bet it has plenty of power :lol:

Nice gun ...............It kinda looks like mine, a little..........Mines a bit different ................Its a nice simple design but that thing must be heavy...Thats what was wrong with mine,so I used lighter weight materials......Mine is still heavy but not like it was.....

Good Job :salute:

One full stop is quite enough per sentence nivekatoz

Is that drop down tube a burst fire mag or is it just a handle?
