Bcm Lower 1/3 A/t Mount Mro Blk

The BCM Lower 1/3 A/T Mount for MRO is a precision optic mounting solution designed for shooters who demand co-witness capability without sacrificing sight picture. Built by Bravo Company Manufacturing, this mount is ideal for those using patrol rifles, precision carbines, or duty weapons, ensuring a reliable connection between primary and secondary sighting systems.

Engineered from hardened steel and finished in mil-spec black, the BCM Lower 1/3 A/T Mount provides robust clamping force and repeatable zero retention, keeping your optic secure under recoil and field stress. Its lower-third co-witness geometry allows users to see their iron sights through or below the MRO's lens, which is critical for weapon transitions and malfunction clearance.

Operators using AR-platform rifles with existing iron sights will benefit most from this mount, especially in law enforcement, military training, or defensive carbine roles where optic redundancy is essential. The compact design adds negligible weight, preserving the carbine's balance during rapid target acquisition.
