QEV 5/2 .50 cal sniper rifle (marble)

Unread postAuthor: anarchy08 » Tue Jun 25, 2013 3:27 am

Hi all,

So I'v been away for awhile thought id come back and check out the forums once again, and to my delight an array of unique pneumatic rifles have joined the showcase.

got me thinking that I should revamp the .50 cal and contribute a little something back into the forum that has taught me so much.

So here she is, not another copper QEV they say. But wait, this is something so much more. For one its actually finished with a body, I see so many fine designs that fall short when it comes to looks and functionality.Without sounding arrogant i hope that this can inspire some to go the extra distance.

The technical stuff:
17mm(20) copper pipe
3/4'' QEV
5 port / 2 way valve capped to perform as 3 port 2 way (normally open)
regulated CO2 up to 350 psi
Bushnell 1x30eg green/ red dot scope (from the 6mm semi(now has laser reflex scope)
SS adjustable latches

Functions:
Bolt action when you feel like it, otherwise functionally semi Auto.(open bolt)
Adjustable 'banded style' detent to combat multi-feed
adjustable latches for a secure front mount to allow collapsible/ customization rifle
Hollow stock with hinge cover for ammo storage
19 shot magazine (spring-fed)
Red/green dot scope
sexy paintjob ;)

Let us know what you think it looks like, due to the pneumatic design there isn't alot of rifles that i could model it after so I took stylings from the Steyr SSG 08 and the M14 in combination with the wooden stock , i just couldnt bring myself to paint it

That's a really nice finish, you've done a great job with it. Would love to see a video of it, even if it's just an overview of the gun.

For some reason I'm reminded of the Ariska Type 2...

thanks for the comments guys, ha was wondering when JSR would stumble across this :P

just received my new foldout gun stand :)

http://www.ebay.com/itm/251218622048?ss ... 1439.l2649

only recently went out and tested it,after refab. marble shattering results :)
got a few small probs to sort, feeding jamming etc but works well and kicks like a shotgun at the 400 psi mark :)

just wondering if anyone has any experience with painball guns? just curious on the chamber volume to barrel length sort of thing as im running too inefficent, ~70 shots per pound of C02 !!!

As I understand it most markers work off hammer valves and very small chamber volumes at high psi correct? im looking at following this and investing in a reg that can do higher pressure. atm up to 450~ psi or so.

As with everyone im after MOAH POWAA :) just small inefficiency's to work out; the breach for example I would like to seal in between shots

anymore comments, criticism welcomed
yeah yeah video or it didn't happen :P soon, promise
