The True North Concepts GripStop S2 is an M-LOK hand stop built for shooters who want a consistent support-hand index and tighter control of their rifle. This handstop bolts to your M-LOK handguard, gives your support hand a positive reference point, keeps your hand from sliding forward over the muzzle, and works as a barricade stop when you brace against cover. As a low-profile alternative to a bulky vertical grip or angled foregrip, it earns its place on the rail without adding weight or snag points. Machined from billet 6061-T6 aluminum and finished in a military-grade Type III hardcoat anodize, the S2 shares the Picatinny GripStop profile and brings K2 ergonomics to a single M-LOK slot.

The single-slot footprint mounts to any M-LOK rail section and leaves the rest of the handguard open for a weapon light, a sling mount, or a pressure switch. That compact footprint makes the S2 an easy add to an AR-15, an AR pistol, a carbine, a PCC, an SBR, a rifle-caliber AR, or anything M-LOK compatible without crowding your setup.

Position the S2 where your support hand naturally falls along the handguard, then tighten it down with M-LOK hardware for a lockup that does not shift under recoil. Driving a thumb-forward C-clamp grip into the stop gives you a repeatable hold that aids recoil management, steadies your muzzle, and helps you track the sights between shots. The integrated barrier stop lets you load against a wall, a barricade, or a vehicle for a stable shooting position on a duty call, a home-defense rifle, or a 3-gun and USPSA stage.

Every GripStop is made in the USA from domestically sourced material and backed by a lifetime, no-questions-asked replacement warranty, so the S2 stays on your rifle build for the long haul. Available in Black and Earth Brown, it carries the same profile across the GripStop line, so your support hand finds the same index whether you run it on an M-LOK or a Picatinny rail.
