I'm def. not used to shooting a Bolt Gun using a Picatinny rail, and low rings. Midway forgot to send me my low rings, and I have a set of lows on the 5R, and my cheek weld still seems a lil high. The other rail I bought for my 243SPS is a Steel Brownells, a bit thicker than the Warne 20moa I'm using on the 5R. Does anyone make a decent cheek rest without having to use the screw on ones, like some of the HSP come factory? I was thinking a slip on, and I shoot lefty, so I could just rev. it. Link anyone? Thanks guys. I have a New set of Talleys, and PRI, and love them, but looks like they will have to go on an AR build.
