The OR3GUN Project™ was born out of 3-Gun, so it is only natural that the first versions of each of our products cater to this core group. We’ve all witnessed the evolution of lessened overhang on the tail of Mossberg’s 930 forearm and the opening of loading ports in the receiver. Mossberg themselves have made minor changes to their recent models in an effort to accommodate faster loading. While techniques and patterns have evolved with loading techniques, they are all limited by the loose tolerances found in the OEM Forearm Retainer. Once again, we've got the solution.

OR3GUN Competition Forearm Retainer

The OR3GUN Competition Forearm Retainer replaces the Mossberg OEM 'Forearm Retainer’ (located on your magazine tube between the forend and receiver) to complement loading ports modified for competition speed loading. The rapid acceptance of new dual and quad loading techniques have required that attention finally be paid to the space between receiver and forearm. The factory configuration leaves just enough gap to regularly catch the extraction lip of shot shells on quad loading attempts. Simply stated, there's a lot of room for improvement to the factory part.

CAD Drawing of OEM vs OR3GUN parts

The OR3GUN CFRs have generously extended forearm retention tangs in order to eliminate the factory forearm flex at the receiver and close the gap between. The portion that overhangs the receiver is also wider than OEM and is either already CNC machined with a 'ramp' (Twins/Quad Ready) an OEM style overlap (Anodized Field Fit) or is left to be further profiled for the individual shooter's preference (RAW Field Fit).

OR3GUN developed the Competition Forearm Retainers for incorporation into new or existing Mossberg 930 loading port modifications. The primary purpose is to raise the forearm higher along the receiver and reduce the gap in front of the loading port.

The 6061 T6 aluminum alloy greatly strengthens this critical component and allows it to blend with your specific loading port and forearm profile.

The Field Fit versions are designed to drop right into your OEM Polymer Forearm and eliminate much of the gap without modification to any components, including those expensive camouflaged forearms. The Satin Polished version will tuck out of sight on standard forearms, while the Anodized is a nice touch for models such as the JM Pro where the CFR will be partially exposed.

The Sporting Fit version is designed to fit the Mossberg Pro Series Sporting model with wood stock. This version is a completely different design with a different radius and tang profile to snug the Pro Series Sporting's premium walnut stock to the receiver. It is anodized in Storm Gray to complement the gray finish of the Pro Series Sporting.

Our most popular CFR versions are the CNC tapered Quads/Twins Ready models in both Anodized and Polished finishes, both of which blend in nicely with most port work. These models can also be found in a variety of colors in special Combos for competition guns.

Due to the maze of ITAR and export regulations on firearm parts, only a specific few of ours are currently for sale outside of the United States to select countries. As most non-combat shotgun parts are exempt from ITAR and conform to the EAR99 category for export, we have begun selling specific combinations of our parts to customers in Canada, Germany and the United Kingdom. If you reside in one of these countries, please make your purchase from our International page only. International orders generated from elsewhere will be cancelled. While shipping charges are calculated and included when you complete your purchase, localized customs fees may be levied at the destination.
