:? Bottle threads on the regulator will be 5/8-18UNF. Outlet thread is 1/2-14NPS BTW. Under the forestock is a better position IMO....if it's thin enough, a cutout in the butt stock perhaps? Largely dependent on how you prefer a rifle to balance. My preference is to have the balance forward on a be...

yeah, i meant to say 5/8 :roll: had a nOOb moment. Ive, also got one of those rectangular black qev's that wyzz done the video on, are they okay for 300psi? probably fit in better and sit a little lower than the alpha qev I've personally taken mine to 800 psi, but I try to keep it below 600 most of...

@gipetto....Its the same qev as the one in wyz's video with the little slide valve
cheap ebay job ya know- its got chinglish written on it.

Hey guys,...If someone could could do me a big favour and convert the specs for this project on ggdp,... eg: firing chamber recomended size, and what fps it will approximatly be shooting at with the finished product it would be very much apreciated.... I would do it myself but its hard when your usi...

@gippeto,.. yeah the thread on my scuba bottle is 3/8, what if i mount it under
the fore stock, i think it would fit nice there?

Thanks fellars,... I want to do it right the first time and not "half-arsed" if you know what i mean.

Hi guys.... I am going to use this (chinese made) full - moulded crossbow stock, for my Qev rifle build. I want it to be semi - auto, (muzzleloading for now is okay). I will be using the following: 1/2 inch 250psi qev , parker 3 way trigger valve, ninja slp 300psi regulator, a 3000psi "spare air" sc...

@JSR , Gippeto , etc... i am going to start a new thread on my build, as
it is morphing into something quite different to mpmrla's. Ive saved this thread
for your diagrams/info jsr, so don't worry.... i won't ask you the same questions
on the new thread, got some pics to show you guys too.

@jack... have you got any of h.m buckley's books?

Can ya make me a .25 cal benjamin maurauder please.
or a evanix monster/windycity, either is good

Pick it up in 2 weeks okay, cool.

@jack....Are yes,.. we can all be smart arses too

"Sarcasm is the lowest form of wit"

@gippeto.... Didn't see any constructive advice coming from your way "Grandma":lol:
Get back in ya "rockin chair"

I can't download that pressure converter you linked for some reason?

Should i just multiply the example conversion page of 100psi x3 to
get my firing tank size?... Looks like its going to be huge, going off
the 100psi calculation?

I noticed the parker 3 way valve is 150psi rated... Am i not
going to be putting 300psi through it? Or does it work the same as
when you explained the qev? You can put a little more through than
its rated for- and all good? - See -, i have been paying attention a
little bit.

You could always buy a sling-shot i guess :wink:.... fits all your criteria and cheap! Pouch/muzzle-loading, spring-powered (sort of), pull-back-and-release, Don't laugh!. Gamekeeper's do 250-300fps+! (chrony tested 9mm ammo) Where?: gamekeeper catapults (ebay.uk) Watch: "amazing slingshot shooting ...
