Before I start I would like to give credit for the idea and inspiration for this to biged http://www.spudfiles.com/forums/m1a1-bazooka-t15933.html. I will be very happy with myself if my combustion version of his gun is near its level.

I am making a break barrel QEV pistol in which the QEV will be housed inside a piece of 1&1/4" PVC to make it look more aesthetically pleasing. the PVC will also be used to have 2 sets of rails( 1 for lazer and 1 for a red dot ) and a pistol grip frame screwed into it.

i was also contemplating putting a little mini reg on it and finding an adapter and pipe that fits around a 12 gram co2 cartage tightly so that i could get multiple shots... what do you think?

Don't say that! A spudgunner never gives in to anything!

You could make a trigger out of some wire or some scrap metal. All you'd need is pliers or a dremel...

the TTP ( Tactical Target Pistol ) will be a 1/4" piston valve or qev pistol. I have spent most of my spring break thinking about it, drawing up its schematics, and researching parts I will order. I am having some trouble making the 1/4" piston though, have many people done that before and do you ...

12"x3/4" pipe nipple for my chamber

3/4" to 1/2" bell reducer for attaching the barrel with a 1/2" filed out male adapter

thank you so much. I can finally begin my sniper

thats what i'm wondering. you say " a proper reducer" but what do you use for your proper reducer to connect the barrel? is it just a nipple that you have the barrel epoxied into or is their another way?

what do people use for attaching a coaxial barrel to the end of their chamber? pics would be appriciated
