Accessories for Mossberg JM 930

The Mossberg JM 930 is a Jerry Miculek-signature gas-operated semi-automatic shotgun designed specifically for competition. Its tuned action and enlarged controls make it ready for IPSC Shotgun from the box, and the accessory range for the JM 930 covers all three competition-critical variables.

Upgrades for the Mossberg JM 930

The Mossberg JM 930 can be tailored across the main competition upgrade areas:

• Stocks – an adjustable stock dials in length of pull and cheek height so the gun mounts the same way every time.
• Handguards and forends – a replacement forend changes where and how your support hand drives the gun, improving control through fast transitions.
• Tube extensions – a magazine tube extension adds shell capacity beyond the factory limit, so fewer reloads break up a stage.
• Red dot mounts and sights – a mounted optic gives a single focal plane for faster acquisition without permanent changes to the receiver.
• Cheek rests – a raised cheek piece keeps your eye consistently behind the optic on every mount.
• Charging handles and controls – enlarged controls are faster and surer to operate under speed.

Compatibility is specific to each model — confirm the fit on the individual product page before ordering.
