Trijicon RMRcc Lower 1/3 Co-Witness Mount w/Q-LOC AC32111

The Trijicon RMRcc Mount AC32111 delivers a high degree of versatility to the most discerning users — combining the correct lower 1/3 co-witness height for iron sight integration with the Q-LOC system's proven zero-retention quick release capability that serious operators and competition shooters specifically reach for when they need fast, reliable optic mounting that does not require a re-zero every time the optic comes off the rifle.

The RMRcc Mount AC32111 lower 1/3 height is specifically sized for co-witnessing with iron sights — placing the RMRcc aiming point in the correct position within the sight picture while keeping iron sights accessible in the lower third of the optical window for reliable backup use. For AR platform shooters who specifically want the lower 1/3 co-witness relationship between their RMRcc and iron sights, the AC32111 delivers that exact height configuration.

The Trijicon RMRcc Lower 1/3 Co-Witness Mount utilizes an innovative spring-loaded attachment mechanism that allows easy mounting and unmounting without needing to re-zero the optic after remounting — a genuinely useful quick-release capability that makes the Q-LOC system practical for operational use rather than just convenient. One-handed mounting, with no tools required, gives operators the fast, intuitive experience that serious users who need to quickly mount or remove their optic especially appreciate.

The Trijicon RMRcc Mount has multiple recoil lugs that ensure full rail engagement and superior resistance to heavy, repeated recoil — a mechanical retention design that keeps the RMRcc secure and zero-retained through sustained shooting. The compact circular design reduces snag hazards on loose clothing and equipment. Precision-cut dimensions ensure compatibility with MIL-STD 1913 Picatinny rails, NATO rails, non-mil-spec rails, and even damaged rails — the broadest practical rail compatibility in a compact, quick-release mount design.
