Since its release in 2013, the GripStop has gone through a series of improvements and design changes based off user feedback. True North Concepts has taken the opportunity to fine tune these changes for the re-release of our Picatinny rail mounted variant. Although the firearms industry has moved away from the 1913 Picatinny mounting interface, it still remains the standard throughout the U.S. Military and most allied nations. The majority of issued weapons are already bulky and heavy, and TNC set out to reduce the weight of the GripStop while improving performance. The result is the lightest, strongest Picatinny variant ever built. This new GripStop weights just 1.7 ounces and is built from 6061-T6 aluminum for maximum durability. It is currently available in both Earth Brown and Black Milspec Type 3 Hardcoat anodized finishes. All hardware is built from tool grade steel and is black Nitrided finished for maximum corrosion resistance. After years of feedback from the field the design now features a specialty flat-head, flush fit mounting screw, allowing any common screwdriver or multitool to be used for mounting and maintenance. The Picatinny rail GripStop carries the same lifetime "No questions asked" replacement warranty as the rest of the GripStop family and is built with military application at the forefront of its design.
