Aimtech ASM-3 Saddle Scope Mount Mossberg 500/590 12 Gauge Black Matte

The Aimtech ASM-3 is a precision-machined saddle scope mount purpose-built for the Mossberg 500, 590, and Maverick 88 series of 12 gauge shotguns. Designed for shooters who want to add an optic to a pump-action shotgun, this dovetail-style base provides a stable platform for mounting compatible optics on the receiver.

Constructed from durable 6061-T6 aluminum and finished in a non-reflective black matte hard-coat anodized coating, the ASM-3 is built to handle the recoil of a 12 gauge while resisting corrosion and wear in the field. The saddle base gives Mossberg pump-action owners a clean and reliable way to outfit their shotgun with an optic for hunting, home defense, or tactical use.

At just 6 oz and measuring approximately 7.45" long x 5.2" wide x 1.9" tall, the Aimtech ASM-3 adds minimal bulk to the host shotgun. It is a straightforward, low-profile upgrade for any Mossberg 500, 590, or Maverick 88 owner looking to mount an optic on their 12 gauge pump.
