Purchased my Gunsite Scout, mfg. in 2015 in 2016. It is in .308. I didn't like the original picatinny rail as the aperture on the ghost ring sight was too small so I ordered a XS Long Piatinny Rail with a larger aperture. I still put an XTR Burris 1 x 6 scope on it, along with a Yankee Hill Flash Hider. Not because I wanted to breech any doors or impale any zombies, but because it just looked bad ass!
