IMPORTANT NOTICE! Although we include mounting screws for the Trijicon RMR, there are approximately 20 other Micro Red Dot Optics that fit the GG&G Mossberg 990 Red Dot Scope Mount. A fitment list is provided in the Specification section below.
Please be advised that the screws that are included with the GG&G Red Dot Mount are specific to mounting the RMR 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 Mossberg 990 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.
The Mossberg 990 Shotgun is a hot new addition to the Mossberg shotgun lineup. More and more, shotguns are being equipped with Red Dot Optics like the Trijicon RMR. Red Dot Optics are an extremely popular tactical accessory for Mossberg shotguns. The GG&G Mossberg 990 Low Profile Red Dot Optic Mount has the RMR fitment or attachment layout. However, the 990 Red Dot Scope Base fits approximately 20 other red dot optics, but beware of screw lengths. The mounting hardware supplied in this package is only tested to fit the Trijicon RMR optic.
The Mossberg 990 Red Dot Mount is a rock solid low profile mount. It is CNC machined to precise tolerance and has incredibly solid engagement with the top of the 990 receiver and with the red dot optic. The Red Dot Scope Mount, coupled with the RMR Red Dot Scope, provides a rugged and accurate quick target acquisition package.
