I modified this airgun to have the same ergonomics/geometry as an AR. The airgun itself is a bolt action Theoben Rapid 17 and it's wearing a Leupold 6.5-20x40 EFR scope on BKL cantilever mounts. I guess it has more similarity in looks to a Barrett but they do have the same geometry as well anyways...

The nice thing is that I get to practice A LOT of precision shooting very cheaply indoors: single hole 5 shots groups at 9 yards, standing, off hand :)

Oh yeah, the stock folds! The buffer tube is attached to the wooden "lower" via an ACE Ltd FSM.

Wow.....that is very cool, I like it Whats the FPS on that honey? Im thinking a Squirrels worst nightmare

fookin' cool.  

~813 fps with 10.5 gr Crossman Premier Heavies to give me about 15.9 ft-lbs at the muzzle (2" drop at 50y). It's a squirrel noggin cracker! Actually, I prefer to do me in some feral pigeons...
