yeah man it's all gone now lol - be careful with that gas ey, if some enviromental people heard you did that , they wont be very happy

In brissy there’s ( on the west side ) Mobile hose fixers, pirtek ( Expensive), Industrial fitting supplies - The best and cheapest !! bunnings and the hardware shops are really going to sting you for air fittings, even a trade tools of truck supply shop like Qld diesel spares would be better

All you want to do is if your using steel bb’s is head to a hobby shop for some brass tube (most bigger toyworld’s stock all different sizes , a lot of them telescoping ) then find your self a bearing shop In an industrial estate near you. CBC bearings are a good one, and there’s a couple of them in...

You can legally buy sling shot ammo in aus. Check out your camping stores or Places likethis not the cheapest, but shipped from aus?

i've thought about this design before but doesn't everyone say that your going to need high pressure for this system to work ?

in this case one hopes the bolt will keep on going past the magazine port even after the air is lost. Thats what i was thinking, i guess this is where the high pressure benefits this application as the "Pulse" of air would have enough power/momentum to push the bolt all the way back past the mag po...

Looking good, I like the idea of the clear casing.. Helps everyone with being able to see it at work, rather than just trying to understand :) I cant wait to see how this turns out. This is where the importance of an adjustable bolt spring comes in, it needs to be tight enough to allow enough pressu...

No there’s no detent or O-Ring at the breach at all. Put the barrel is a tight fit and i don't ever have a BB roll down the barrel ? One thing i keep thinking about with that is aren’t you worried that if you create too much friction holding the bb, wont the bolt open (releasing pressure )before the...

what pressure are you using this would really need 250+ At the moment im only running at 100-120psi for testing , although I have the capabilities to run higher , but I would like to see if I could get this to work at 100psi since not everyone has a shock pump or fridge comp. @ JSR- I had a good re...

Hey all, I've just come back after a while off and am now ready start up again. And for as long as i can think i've wanted to build a blow back system. So I’ve had a good look around and done a lot of reading but want to run a few questions past everyone.. JSR posted a few pics of different setups o...

yeah man beautiful build !! and so slim

So is there any chance of some broken down photo's please ??

nice build man

I'd try changing your projectile ?? maybe steel balls ?
smooth bore @ 100psi you should be able to hit consistently 10 - 15m mine does well over 12m at least 4/5 keep it up and good luck

if anything you could strip the internals and use it as a nice stock/cover

chinnerz - thanks man :D sorry been away a while aww are you going to at least paint it? Or make a cover for the working parts so they don't get damaged? Na i don't think im going to paint it , but i would like to make some covers to hide the QEV. thinking about it i should of borrow'd a router for ...

Hey all .. ok so this really isn't anything new it's the same barrel setup i've already had here with the same style of stock but i recently got given a 1/4" Qev from a mate and wanted to give it a go.. Ok So how good is a Qev ?? (might sound weird but this would be my first experience with one) but...
