The 360 Precision Low Profile ARCA Rail 9″ is a lightweight, M-LOK-mounted ARCA dovetail rail that lets you connect bipods, tripods, plate adapters, and other ARCA-compatible accessories to the underside of your rifle. It includes (3) 10-24 screws and (3) M-LOK nuts for mounting to any M-LOK handguard or forend. Built from 6061-T6511 aluminum and anodized for protection, the rail measures 9″ long, 0.19″ thick, and weighs just 2.8 oz. It also features Really Right Stuff’s R-Lock dimples for added anti-slip engagement with compatible RRS clamps (including the ARC-LR) and other ARCA-based attachments.
What is an ARCA rail?
An ARCA rail (often called ARCA-Swiss) is a standardized dovetail mounting profile that allows an ARCA clamp to slide on and lock down tight. On a rifle, it gives you a strong, adjustable attachment point for tripod heads, bipods, bag riders, and other support accessories — without being stuck to one fixed position.
How does an ARCA rail work?
An ARCA clamp grips the angled dovetail sides of the rail, creating a secure hold that resists shifting under load. You can slide the clamp to fine-tune balance and position, then tighten it to lock in place. The R-Lock dimples add extra bite with compatible clamps to help reduce slip, especially when shooting from awkward angles or under recoil.
