CoaxV2Power

Unread postAuthor: elitesniper » Sun Apr 20, 2008 7:52 pm

Hello fellow spudders its about time I submitted a new cannon to show you all, and here she is :D , following my first coax the anti tank one, witch failed miserably( filled way to fast, piston shot up hit the barrel and crapped it up, beacause I had a crap barrel support. Now on to the new and improved one, it now has a barrel support consisting of a 3/4x2'' bushing hollowed out and cut the circle out making and X shape fitting almost snugly into the 2'' chamber.
It has a nifty little laser aiming system held in by Velcro tape, operated by a small pressure switch that you press with your thumb while you hold it(I hold it from the waist, thats why its all the way up there), has a 3/4'' barrel, yes I know, could be longer, but I made it short so it looks way better, performance is killer! It has almost as much ''push'', as BigBlue, The whole thing is 4 feet long and serviceable, piston is made of 1 1/4 coupling cut, it seals on a toilet plunger rubber, witch seals perfectly, the bumper consist of the toilet plunger rim. Id say she's shooting over 500fps. I hope you guys like her :)

Goddamnit, I help you with your first piston, and a few months later you're crapping piston cannons out by the week :D

No fair, bloody expensive NZ prices..


Once again, nice stuff :)

Nice cannon, and I really like the sight you put on there. How much did that run you?

Sweet shotgun blast there. I like the M4 sight on the top. Also, looks light enough to shoot like a rifle.

Nice gun overall...I'm partial to coax pneumatics. Good Job!

yeah, I love that website, thanks guys, the buck shot quite surprised me too, I found that when your doing buckshots it works better out of smaller barrels like 1/2 and 3/4 anything bigger then that the shots are really weak. And i don't think I can hold it like a rifle, it weights 6 pounds :o

My Springfield 1903A3 only weighs 8lbs and it's a pleasure to hold and shoot. :)

More about bulk relaly, I understand. A launcher designed the way you did should be shoulder-held anyway. Thought about making JSR angry and running a small hose from the pilot valve to make the firing a bit more ergonomic? :P

yeah that firing system was on my anti-tank coax a while back but I switched it back due to the power and, I like holding it at the waist more since I have the laser. :)
