MOD-C shotgun light mount The CDM Gear MOD-C light mount is a superior, light weight clamp (weighs only 1.8oz), small and compact enough to reduce your shotgun profile so it reduces hang ups and snags. Spaced between the barrel and magazine tube it will not block your parallel peripheral sight picture. Manufactured from 6061-T6 aluminum and hard coat anodized, it will not crack, break or shrink over time like plastic mounts. One tool for one bolt is all that is needed to attach and remove this clamp in seconds. Holds lights 1" lights and comes with all wrenches and 3M polyurethane no slip grip pads to protect your finish. Includes a built in non rotational sling swivel cup for QD PB sling swivels.CDM Gear offers a factory look with a low profile that doesn't need to be removed when stowed in a case or riding in a gun rack. The design makes for a cleaner look with less snags to worry about, giving you professional control of your weapon. With illumination and targeting systems getting smaller, lighter and more compact, we're offering a professional mounting platform that provides for a stronger, less complicated attachment for your weapon.

Fits Remington 870, 1100, 1187, Mossberg 500 7 shot, 590 (not the 590A1 or SPX models, see MTC clamp), Winchester 1300, 1200 and SXP Defender.
