Vang Comp Rear Sight with Aimpoint ACRO Mount for Mossberg Factory Holes (Except 590R/590RM)

Precision Rear Sight with Integrated Aimpoint ACRO Mount for Mossberg Shotguns

Upgrade your Mossberg with a streamlined rear sight and optic mounting solution built for real-world performance. The Vang Comp Rear Sight with Integrated Aimpoint ACRO Mount is CNC-machined from billet 6061-T6 aluminum and designed to mount directly to factory-drilled and tapped receivers (excluding 590R and 590RM models).

This setup combines a rugged, wing-protected ghost ring rear sight with a low-profile ACRO footprint mount, eliminating the need for bulky Picatinny rails. The result is a cleaner profile, improved cheek weld, and faster sight acquisition. Precision 1/4 MOA click adjustments for windage and elevation allow for repeatable zeroing, while maintaining a dependable co-witness with most factory-height front sights.
