I have two Premier Reticle Tactical, the 3-15x and 5-25x, and i love them more than any other scope. Especially the 5-25 heritage tactical, at my point of view, one of the best Tactical Scope around in the market aviable, the only scope atm i would prefer of the PR's would be a Leupold MK8 (if aviable).
My one is mounted on a Recknagel ERA-TAC blockmount, which is pretty expensive, but here in europe something of the best you can get for your bucks.
I dont know if they're well known over seas so here's the link:http://era-tac.de/index.php/en/products/one-piece-mounts
With QD one piece mount - the cool thing is, after closing QD, you're fixin the mount with 2-3 screwturns.
few days ago i had broken ARMS #22 rings on my savage while shooting, this made me very curious and i decided to exchange everything to era-tac and/or barrett-rings soon.
