Dedicated barrel clamp for your Mossberg 940 Pro shotgun. This barrel clamp features an integrated 1913/picatinny rail and two QD mounts, one on each side. The 1913 rail has 6 positions and is cantilevered towards the muzzle for comfortable mounting of all shapes and sizes of weapon lights, including full power handgun lights such as SureFire® X300 and Streamlight® TLR1. By replacing the polymer molded barrel clamp on your 940 Pro with our rock-solid aluminum barrel clamp you gain additional rigidity and unique mounting options. Our precise clamp diameters and centerline spacing geometry are guaranteed to hold your extension tube perfectly concentric with the magazine tube, allowing the spring and follower to travel smoothly and feed with 100% reliability no matter the conditions.

All of our Mossberg 940 Pro barrel clamps are machined from billet 6061T6 aluminum and hard coat anodized to MIL-A-8625. They include high temp gaskets which can be used as a protective layer between our clamp and your barrel/tube if desired. Our 940 pro barrel clamps have been stress tested in numerous configurations and are suitable for hard/professional use. When used with the supplied gaskets, this barrel clamp is backwards compatible with Mossberg 590 models, as well as 930 Tactical and SPX models.
