Am Def Holosun 510c Qr Lower 1/3

The Am Def Holosun 510c Qr Lower 1/3 provides a rock-solid mounting solution for shooters looking to optimize their optical height on modern carbine platforms. Designed specifically to elevate the Holosun 510C reflex sight, this mount achieves a lower 1/3 co-witness, allowing iron sights to remain visible in the lower portion of the optic window without obscuring the target. Whether you are a law enforcement professional or a civilian enthusiast, this mount ensures your optic sits at the ideal height for rapid target acquisition and a natural cheek weld.

Precision machined from 6061 T6 aluminum, the American Defense Mfg AD-510C mount is engineered to withstand the rigors of heavy recoil and duty use. It features a Type 3 Mil-Spec hard coat anodized finish for maximum corrosion resistance and surface durability in harsh environments. The system utilizes the patented QD Auto Lock Lever, which provides a repeatable return-to-zero and can be adjusted to fit both in-spec and out-of-spec Picatinny rail systems without the use of tools.

This mounting system is the preferred choice for operators who require the ability to quickly detach their primary optic for maintenance or emergency transitions to backup sights. It is fully compatible with the Holosun 510C reflex sight, offering a streamlined profile that reduces snag points on your tactical gear or rifle bag. When you buy this professional-grade mount, you are investing in American-made reliability and superior specifications to ensure your optic remains zeroed regardless of field conditions.
