I really like the sleeved barrel, it looks sweet! :thumbup:

thanks

This is my new coax,is a little bigger than the old one,so more powerful, and looks much better .Made by 1m 15mm Dia coper tube, 160 psi.

Could you post a video of it in action ??

I'm working on a video now

I have been trying to make ou mod a QEV semi-auto for a long time, but I got no where :( .Recently I got a idea to make a semi-auto blowgun to pilot a qev to get a semi-auto qev sistem,and here it is :D .The chamber is 30cm 1'dia metal tubo,charged to 160 psi, and I can shot a amazine 40 times! :D(n...

I dont quite understand how you thought this had 2 chambers. Well technically the HPA tank counts as a second chamber which feeds into your firing chamber, I think what he meant was that commerical multishot pneumatics only have one on-board reservoir, and as they use hammer valves there's no need ...

But I think real semi auto only need one chamber,this one you need continue air to charge the chamber, to be portable you need a segund and big chamber :roll: i totaly disagree. semi automatic means that with each pull of the trigger it fires. it does this regardless of if it uses a constant air fe...

I agree with Jack, with a pilot that size, disconnecting a schrader shouldn't cause the gun to discharge. and more pressure = more fun

Also have you modded that blowgun to increase flow?

well i didn't mod the blow gun valve, wasn't necessary.

Good first effort, the pilot area is rather large but hey, if it works, it works. Why the ball valve though? Does it fire when you disconnect the schrader? Since you're working with metal, a good way to get more power would be to use a smaller chamber and up the pressure using a shock pump to take ...

I like it looks very nice

well I build this gun in about 1h,as a frist try at coax air guns.
It works very well,the piston opens pretty fast .The gun is made of 80cm of steel tube and a 6mm tube for barrel.The piston is pilot by a blowgun valve,operatin presure:20-200psi.The scope is 4*38,I bought is for 35 euro.

I do have pics of the internals.

nice gun put more info, pressure, barrle length and dia
and if you can get a pic of the piston

I do have pics of that qev,the barrel is 60cm long with 6mm dia for shooting bbs.
