American Defense LW TR DPP/EFLX QD Lower 1/3 Co-Witness Mount - Precision Optics Mount for Tactical Applications

The American Defense LW TR DPP/EFLX QD Lower 1/3 Co-Witness Mount is a precision optics mount built for shooters running compact red dot systems on AR pistols and short-barreled rifles. This one-piece mount accommodates the EoTech EFLX, Leupold Delta Point, Delta Point Pro, and Vortex Defender—some of the most popular miniature red dots in tactical and defensive use. If you're building a pistol-length AR or want a lightweight optic solution that co-witnesses with your iron sights, this is engineered to get the job done without unnecessary weight or complexity.

American Defense machined this mount from 6061 T6 aluminum and finished it in hard coat anodized steel (Mil-Spec T3), a combination that delivers durability without bulk. At 30 percent lighter than standard ADM mounts, it won't throw off your balance on an already compact platform. The one-piece design eliminates the leverage points and potential slop that plague two-piece systems, and the patented QD Auto Lock Lever system clamps securely to both in-spec and out-of-spec Picatinny rails—a real-world advantage if your upper isn't perfectly within tolerance.

The mount offers multiple optic heights: true co-witness, lower 1/3 co-witness, 1.93" for heads-up shooting, and 2.33" if you're pairing it with night vision. Adjustment doesn't require proprietary tools—your finger or a standard flathead screwdriver is all you need. For AR pistol builders and shooters who demand a rock-solid, featherweight platform for their red dot, this mount delivers precision without the premium price tag of heavier alternatives.
