Lead & Steel Llc
The Lead & Steel LLC GAP-RMR is a steel mounting base engineered to get your RMR or ACRO red dot sight onto your slide or receiver with rock-solid repeatability. If you're running a micro red dot on a pistol, rifle, or shotgun, this oxide black steel base gives you the rigid interface those compact optics need—no plastic, no flex, no excuses. Whether you're building a carry gun, a competition setup, or a precision rifle platform, this is the kind of invisible-until-you-need-it hardware that separates a solid build from one that shifts zero at the worst moment.
Oxide black steel construction means durability without the fuss. It's corrosion-resistant, finished to handle hard use, and built to blend into your gun without adding bulk or weight. The GAP-RMR accepts both RMR and ACRO footprints, so you've got flexibility if you ever switch between optics—a smart hedge in a market where red dot designs keep evolving.
Lead & Steel LLC has built a reputation doing one thing well: no-nonsense mounting solutions that gun builders and gunsmiths actually reach for. This base isn't trying to impress anyone; it's just engineered to stay put and let your optic do the work.
| Brand | Lead & Steel LLC |
| Product Type | RMR/ACRO Mounting Base |
| Finish | Oxide Black Steel |
| Optic Compatibility | RMR, ACRO |
Yes—the GAP-RMR accepts both RMR and ACRO footprints, so you can run either optic on the same base.
This is a mounting base, so compatibility depends on whether your firearm has a compatible mounting surface (typically a slide, receiver, or Picatinny rail). Check with your gunsmith or firearm manufacturer to confirm fitment for your specific gun.
Yes—it's finished in oxide black steel, which provides corrosion resistance for hard use in the field.
