IMPORTANT NOTICE! Although we include mounting screws for the Trijicon RMR, there are approximately 18 other Micro Red Dot Optics that fit the GG&G Beretta A300 20ga Ultima Patrol RMR Scope Mount. An Optic Compatability list is provided in the Specification section below.
Please be advised that the screws that are included with the GG&G Trijicon RMR Mount are specific to mounting the RMR optic and may be too long for mounting other red dot optics. For example three Holosun Mini Red Dot Scopes, models 407, 507 and 508 have the same attachment screw layout as the Trijicon RMR. HOWEVER, BE ADVISED: The screws that come with the GG&G Beretta A300 RMR Mount ARE TOO LONG TO MOUNT THE HOLOSUN OPTICS! If you attempt to mount these Holosuns or any of the other optics listed below, you may dimple the top of the receiver!
Ensure you have the proper length screws prior to installing any other optic than the Trijicon RMR! PROCEED WITH CAUTION! DAMAGE TO YOUR RECEIVER COULD OCCUR.

Beretta A300 20 ga Ultima Patrol Trijicon RMR Scope Mount
Red Dot Optics like the Trijicon RMR are extremely popular as a hot tactical accessory for shotguns. The GG&G A300 20ga Red Dot Mount is low profile and a solid mount for the Beretta A300 20ga Ultima Patrol Shotgun. CNC machined from solid billet 6061-T6 aircraft grade aluminum to precise tolerance, insures a rock solid engagement with the top of the Beretta A300 20 ga receiver and the RMR scope. Its finish is matt black-Type III hard coat anodized per Mil-Spec to protect it from the elements.
The Beretta A300 20 ga Ultima Patrol Mount is positioned to allow true center co-witnessing with the factory sights. The package includes mounting hardware for mounting the RMR Scope Mount to the Beretta A300 20ga receiver and hardware specifically for mounting the Trijicon RMR to the scope mount.
