Mike, The one and only Picatinny rail I have is a 20 MOA on a heavy barrel Savage Model 10, in 308. The rifle was purchased to shoot the bench rest game, 100 yard Score Shooting, or Bulls Eye shooting. The 36 X Sightron was never clear and , and the image was never sharp. I sent the scope back to Sightron and I received a call from them asking Why I had the scope adjusted to max as it did. They asked me if I was using a rail with MOA built in to the rail. I said yes!! The said please used regular Rings and Basses as the scope has sufficient elevation to shoot the 308 , at 600 yards or more, with enough internal elevation movement. All my hunting rifles use 2 piece steel Leupold Rings and bases and my favorite are the Dual Dove Tail Rings and Base set up. The picture is my 270 Weatherby Mag, with a Leupold 4.5X to 14 X scope. I also shoot this rifle at a LR shooting school, with the Leupold 8.5 X to25 X Leupold VX 3 . All I did was remove the scope you see in the picture , and pop on the other. 1000, and 1200 yard steel shooting was not a problem at all with this set up. Plenty of MOA elevation adjustment in the scope, no need for a MOA rail at that range, with that caliber. over a 100 rounds fired prior to attending the shooting school, and 85 rounds fired in two days at the school. A very secure and strong set up for a hunting rifle. Just my personal opinion Mike .
