Precision Hardcore Gear Tru Level 1-Piece 20 MOA Elevated Picatinny Scope Base Remington 700 Short Action with Integral Bubble Level Matte Black

From MidwayUSA

The Tru Level from Precision Hardcore Gear delivers two critical components to long range accuracy. First things first, hunters and shooters need to be able to trust that their base will securely hold an optic for repeatable accuracy and the Tru Level does exactly that. But what good is a solid base if your rifle is canted just a frog's hair to the right? The Tru-Level solves that problem simply by integrating a high quality bubble level into the rear of the base. Shooters can check that the firearm is perfectly level without even moving out of the shooting position.
