The RS Regulate 12 Gauge Barrel Accessory Mount is a Picatinny rail system built for hunters and tactical shooters who run tube-fed shotguns and need a solid platform for lights, lasers, or other optics. This is one of the few aftermarket mounting solutions designed specifically to clear the mag tube on traditional shotgun profiles, giving you real modularity without the jerry-rigged solutions that limit reliability.
RS Regulate engineered the BM-12G with self-adjusting clamp arms that grip your barrel securely without fiddly manual adjustment—it shoulders the load and stays put through recoil. The mount carries a full 4-slot 1913 Picatinny rail, so you can attach standard-pattern accessories without adapters or proprietary brackets. Everything is manufactured in the USA from 6061-T6 aluminum, hard anodized to mil-spec finish, with stainless steel hardware throughout. That level of material selection matters on a shotgun, where rust and corrosion can develop fast in field conditions.
Whether you're adding a weapon-mounted light for home defense, mounting a laser for slug hunting, or building a modern tactical shotgun, the RS Regulate 12 gauge mount gives you the foundation to do it right. It's the kind of accessory that works silently in the background and doesn't fail when you need it.

The BM-12G is designed for traditional tube-fed 12 gauge shotguns. The self-adjusting clamp arms are engineered to fit standard barrel profiles on that platform. If you have questions about fit on your specific model, contact us.
Yes. Shotguns see moisture, salt spray, and harsh field conditions. Stainless hardware resists rust and corrosion far better than standard steel, so your mount stays reliable season after season without seizing or deteriorating.
Rather than requiring you to manually dial in the clamp tension, the arms are engineered to conform to your barrel and hold it securely without fuss. Tighten the hardware and the mount adapts—less time fiddling, more time shooting.
