Gruning Heavy Duty Tactical Optics Bases provide the ultimate in durability and precision.

The lower surface of the base has an extra-wide contact area for maximum stability. The receiver gains added stiffness for maximum accuracy.

A precision-ground location pin fits into your receiver for extra shear-strength against recoil, and to ensure that the base is precisely aligned with the rifle's bore. 

Standard installation includes rethreading receiver from 6-48 to much stronger 8-40 screws for a very significant increase in strength. We don't just follow the factory holes, but set each receiver up so that the new holes are precisely aligned with the bore (not always the case off the factory production line).

The base is built with some extra length in front so the user has flexibility to mount optics forward for comfortable prone shooting.

Whether you are a professional operating in the most extreme conditions, or a hunter or target shooter looking for maximum stability in a scope mount, the Gruning Heavy Duty Tactical Optics Base is the ideal choice.

Comes in Steel, and High-Strength Aluminum.

Available for Remington short and long actions
