Product description

The Aimpoint® COA™ is a purpose-built pistol red dot sight engineered for fast, instinctive shooting and a low-profile carry footprint. Its ultra-compact, tubeless construction minimizes visual obstruction and promotes quick target acquisition, resulting in a lightweight and discreet optic well suited for concealed carry. COA is intended for users who prioritize speed, simplicity, and dependable performance in everyday carry environments and who rely on a clear, unobstructed aiming solution for close-range accuracy.

This sight mounts exclusively through the slide-integrated A-CUT™ interface. The optic sits low, remains precisely aligned with the bore, and locks securely into place without any screws entering the sight housing. The A-CUT mounting architecture ensures a consistent attachment that supports reliable operation across pistol platforms designed or machined for this interface.

The COA sight incorporates the A-CUT interface directly as part of its design, using a front hook and rear wedge to create a mechanically locked connection with the slide. Because the mounting method requires no screws inside the housing, the sight retains structural integrity even under demanding use. Its 3.5 MOA dot and unlimited eye relief contribute to rapid target engagement and intuitive alignment.

A dedicated pistol sight for everyday carry, the Aimpoint® COA™ delivers fast target acquisition, a streamlined form factor, and consistent performance you can trust.
