True North Concepts redesigned its innovative Gripstop to be better than ever before, and this helpful forend stop is even built with our troops in mind, giving them an attachment system that's easier to use with available tools in the field. All those features are a benefit to the civilian shooter as well! Each True North Concepts Gripstop is designed to attach to any standard Picatinny rail. Rather than using the standard Allen key attachment screws, though, this Gripstop uses a flat-tip screw head, which allows the unit to be mounted or tightened using a standard flathead screwdriver, multitool or any other flat blade. The True North Concepts Gripstop is machined from 606 Mfg: True North Concepts
