About This Beretta A300/1301 Mount

This low-profile direct mount connects the optic to a tapped Beretta A300 or 1301 receiver without a separate Picatinny rail and optic mount.

Compatibility

This mount fits any Beretta A300 or 1301 with a tapped receiver.

Installation Notes

Unload the firearm completely. Remove the magazine, clear the chamber, and remove any factory rail or other mount. Position the Armadyne mount on the tapped receiver and secure it with the supplied two M4 x 0.7 x 6 mm screws.

Attach the optic to the mount and dry-fit the assembly on the receiver before final installation. Confirm that no optic screw protrudes far enough to contact or scratch the receiver.

Tighten the M4 receiver screws to 10 in-lb when installed dry. Liquid thread locker is optional; if used, reduce the torque to 7.5 in-lb.

Follow the installation instructions for the complete optic-screw check, torque values, and optional thread locker guidance.
