A fully integrated, low-profile mounting interface for pistol optics

A precision-machined interface for direct optic mounting

A-CUT is a precisely machined opening in the pistol slide that allows direct mounting of Aimpoint™ COA™ sight without adapter plates. This integrated system ensures a low, stable, and repeatable zero for unmatched performance.

Unmatched stability and speed

Unlike traditional mounts, the A-CUT design avoids the sheering effect that faces many interfaces today. A wedge-locking mechanism transfers lateral forces into the dovetail, reducing load on screws and mounting interfaces. This results in high durability and reliable zero retention under demanding conditions. Because the sight sits exceptionally low, A-CUT enables co-witness with factory iron sights, supporting fast, instinctive target acquisition and a more natural shooting experience. 

How to mount an COA sight on a pistol with A-CUT

1. Position the COA sightPlace the COA optic into the A-CUT interface on the slide. The interface secures the optic and prevents movement. 2. Secure the COA sightUse the supplied screws and torque them to the recommended specification. 3. Verify alignmentConfirm that the sight is seated correctly and co-witnesses with the iron sights. The pistol is now ready to be zeroed. Download user manual >

Fire a groupFire a three to five round group to observe point of impact relative to point of aim. 3. Adjust the sightUse the elevation and windage adjustment screws with a T10 Torx tool.

The COA®

The Aimpoint ® COA® maintains the ruggedness and reliability of the ACRO® series in a smaller, more compact form. This concealed carry optic features a fully enclosed emitter providing superior protection against debris, dust and other environmental elements - making it an excellent choice for professional, personal protection, and sport shooters alike.

A wide field of view with a narrow frame provides great situational awareness. The user will perceive a larger aperture due to the construction without an inner tube. The robust iron sight, which is part of the mounting solution, enables co-witnessing.
