Seekins Precision ARCA Rail 5 Slot M-LOK 11" Black Anodized

The Seekins Precision ARCA Rail is part of the company's Modular Rifle ARCA System (MRAS), a strong, durable, and lightweight accessory rail that mounts directly to any M-LOK handguard. Machined from 6061-T6 aluminum and finished in black Type III hardcoat anodize, this 11-inch rail features 5 integrated M-LOK slots and a scalloped design that trims weight without sacrificing rigidity.

The ARCA profile is compatible with most makes and models of tripods and bipods that use the ARCA Swiss standard, making this rail a natural fit for precision rifle setups. The integrated M-LOK slots allow the rail to attach securely to M-LOK-equipped AR-15 and AR-10 handguards using the included hardware, and the design pairs with Seekins' separately available MRAC (Mounted Rail Attachment Clamp) for shooters who want a quick-detach option.

Whether you are shooting prone from a tripod, dialing in long-range holds, or just want a clean ARCA interface on your rifle, this MRAS rail delivers the strength, low weight, and versatile mounting points a precision shooter needs.
