Product Overview

QTR-LT™ Stop - A narrower variant of our popular QTR Stop, the QTR-LT Stop was specifically designed for the MCX-Rattler LT rail for a foreign defense contract. Designed as a lightweight solution to prevent shooters from slipping a hand in front of the muzzle, and filling the side gaps up to the rail to prevent heat exposure from muzzle blasts. The QTR-LT Stop works as intended on any Sig MCX-SPEAR LT/Rattler LT rails, as well as many other M-LOK forend rails (see compatibility list below). Its upward ears were designed to flow and mate specifically with the Sig LT-rail profile to create a wide and seamless barrier. Made out of 7075 Aluminum and hard anodized in Carbon Black or Terra Bronze, and weighing in at just under half an ounce. The QTR-LT Stop takes up only 1/2 M-LOK slot at the end of the rail by utilizing a mini M-LOK recoil lug that hangs over the front lip of the rail. The QTR-LT Stop creates a perfect indexing point to bring the rifle on target securely and consistently. Mounts to 0.625" wide M-LOK flat or narrower.
