QTR™ Stop - Our new QTR Stop is a wide hand stop for M-LOK forends, specifically for Sig Sauer MCX Virtus & Rattler U-rail systems. 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. Specifically designed for the 5.56 Rattler U-rail for a Foreign defense contract, the QTR Wide Stop works as intended on any Sig MCX Virtus / Rattler U-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 U-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 Wide 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 Wide Stop creates a perfect indexing point to bring the rifle on target securely and consistently. Mounts to 0.925" wide M-LOK flat or narrower.
