Seekins Precision
The Seekins Precision MRAS M-LOK Mounted Rail Attachment System is a modular aluminum accessory rail designed for shooters who need flexible mounting options on M-LOK compatible firearms. Built from aluminum and finished in black anodize, this rail attachment system lets you add ARCA-compatible mounting points to your existing M-LOK slots—a smart solution if you're running a scope or accessory that uses ARCA rails but your gun doesn't have native ARCA mounts.
M-LOK has become the standard across modern rifle handguards and chassis systems, and the MRAS fills a real gap: instead of swapping out your whole handguard, you can clip this rail directly into any M-LOK slot and gain ARCA versatility. The 5-slot ARCA profile gives you positioning flexibility, so you can dial in exactly where your optic or accessory mounts. The aluminum construction keeps weight minimal without sacrificing rigidity—important if you're building a lightweight hunting rifle or a precision range gun where every ounce counts.
This is one of those accessories that pays for itself the first time you avoid a full handguard replacement. Whether you're upgrading an existing rifle or planning a build around M-LOK components, the MRAS bridges the gap between your current setup and ARCA-based optics and gear.
