ADM AD-DELTA-L-30-FDE-STD: AD-DELTA 30mm Low FDE Scope Mount w/Dual QD STD Lever

The ADM AD-DELTA 30mm Low FDE Scope Mount AD-DELTA-L-30-FDE-STD is a precision-engineered mount designed to securely hold 30mm rifle scopes. ADM AD-DELTA-L-30-FDE-STD features a low-profile design and utilizes American Defense Manufacturing’s patented Dual Quick Detach (QD) Auto Lock levers for fast and repeatable attachment to any standard Picatinny rail. Built for stability and durability, the DELTA-L is compatible with our DELTA ring caps for adding a secondary red dot or picatinny-mounted item.

The ADM AD-DELTA Mount is specifically designed for mounting high-power optics on rifles like the FN SCAR or flat-top AR-10 platforms. Engineered as a straight-up scope mount with no built-in eye relief, it delivers a solid and precise mounting solution. 

Constructed from durable 6061-T6 aluminum and finished with a Mil-Spec Type III hard coat anodizing, the mount offers excellent strength and corrosion resistance. ADM AD-DELTA Mount features horizontal ring caps for a secure grip on the optic and is equipped with ADM’s patented QD Auto Lock Lever system, ensuring reliable, repeatable lock-up on both in-spec and out-of-spec rail systems.

The AD-DELTA-L variant is tailored for bolt-action rifles and chassis systems, where a low optic mounting height is preferred. This model includes integrated recoil lugs that help distribute recoil forces more effectively, enhancing stability and repeatability.

Additionally, the DELTA-L is compatible with ADM's DELTA ring caps, allowing users to mount secondary optics or accessories such as red dot sights or other Picatinny-mounted devices.
