The NEW COA Glock First Look
This guide details the installation of the Aimpoint COA (Custom Optic Adapter) system on compatible Glock models, as demonstrated by Lenny Magill, Founder/CEO of GlockStore. The system features a unique screwless mounting mechanism that allows the optic to sit low enough for co-witnessing with standard iron sights. The process involves removing the rear sight, aligning the optic, and securing it with a rear clamp mechanism.
