American Defense Mfg | Lightweight TR RMSc Mount | Lower 1/3

The American Defense Mfg Lightweight TR QD mount is a compact, one-piece optic mount engineered for RMSc-footprint red dots such as the EoTech EFLX, Leupold Delta Point/Delta Point Pro, and Vortex Defender. It was developed for use on AR pistols and other short-barrel platforms where a small, light optic package is required. The mount offers multiple optic heights including lower 1/3 co-witness, a full co-witness option, and dedicated high and night-vision heights. Construction uses aircraft-grade materials and a patented quick-detach locking system for repeatable attachment.
