Egw remington 700 picatinny rail - Evolution Gun Works Picatinny Scope Mount, Remington Model 541, Long Action Rifle Rail Mount

This rail seems to be of very good quality and installed easily with included screws and wrench. My scope rings mount solidly and my rifle shoots normal good groups. The nice thing about a rail is that you can adjust a scope's position along it to suit you, and you can quickly change scopes on a rifle, or between similar rifles. The only real drawback is that the scope mounts higher than with traditional low bases, so you will want to get the lowest rings that will work for your particular set-up. Even then, adding a cheek riser may be necessary for a good cheek weld.
