I made it breech loaded today. Took me 3 dremel cut off disks, 2 dremel grinding wheels and a drill bit, all wrecked :?
I'll put up pictures if anyone's interested.

Thanks warhead, another great compliment :D pics are up.
I'm working on a suppressor at the minute.

WOW, just did a test shot with an epicly tumbling nail dart and got about 150m down a field :D

I know this is quite an old topic but I've added a handle to the barrel support and finally finished the suppressor, makes a pretty cool noise now! I'll put pics up tomorrow if anyone wants. :D
Just looking at it now I've realized how ridiculously long it is! You need to angle it to get it through doors :?

Cool concept but alot of unwanted materials there like that ball valve on the QEV, also your loading mechanism looks a bit flimsy

Sorry, didn't notice that last post. The Breech loading is pretty solid, I was worried seeing as its copper, but it's pretty solid. I will try and finally get some pics of the suppressor up tonight!
Oh, and something I forgot in the first post, lots of thanks to JSR for all his help with explaining QEVs and suppressors to me and helping with air tank volumes!
