Availability: In Stock
The American Defense Trijicon MRO LW QR Lower 1/3 Co-Witness Mount delivers a lighter, cleaner setup for shooters running the Trijicon Miniature Rifle Optic on AR platforms and other Picatinny rails. This precision-engineered mount shaves 20% off the weight of traditional alternatives while opening up your sight picture for better target awareness—a real advantage whether you're at the range, hunting, or training. Built from 6061-T6 aluminum and finished in hard coat mil-spec anodize, it's designed to handle serious use without breaking down.
What sets this mount apart is the Patented QD Auto Lock Lever system, which grips both in-spec and out-of-spec rail systems with equal authority. No proprietary tools needed—adjust the clamp with your finger or a flat-blade screwdriver, and configure the lever to lock forward or rearward depending on your setup. The clamping surface is engineered to maximize rail contact and hold zero through hard shooting.
If you're building a lightweight MRO setup or just want to trim ounces without sacrificing repeatability, this mount earns its place on your upper receiver.
