The Seekins Precision ARCA M-LOK Mount is a 3.30" anodized aluminum rail designed to integrate ARCA rail accessories into your AR platform or other M-LOK-equipped systems. Built by a maker known for precision small-batch components, this mount bridges two of the most popular modern mounting standards, letting you run scout lights, bipods, slings, bags, or other ARCA-compatible gear in ways a standard M-LOK slot alone won't allow. If you're running an AR-15 or any rifle with M-LOK real estate and want flexible mounting options without permanent modifications, this is a straightforward, durable solution.
Black hard-anodized aluminum means the finish will stand up to field use—it's the same process you'll find on quality optics and AR parts. At 3.30 inches, it's long enough to mount multiple accessories or position a single piece exactly where you want it, but short enough to avoid excess rail weight or snag. M-LOK attachment means it interfaces cleanly with the slots your handguard or rail already has; no proprietary adapters or workarounds needed.
Whether you're building a precision rifle, a lightweight hunting AR, or a modular training gun, a quality ARCA mount expands your accessory ecosystem. Seekins components are known for holding tight tolerances and staying put under recoil, so once you mount it and lock down your gear, it stays where you set it.

Frequently Asked Questions
What AR accessories will work with this mount?
Any accessory that features an ARCA rail profile will fit this mount. Common examples include ARCA-compatible bipods, scout light mounts, bag stops, and quick-detach systems. Check your accessory specs to confirm ARCA compatibility.
Does this mount work on any rifle, or just AR-15s?
This mount requires M-LOK slots to secure it, so it will work on any rifle, handguard, or rail system equipped with M-LOK. It's commonly used on AR platforms, but also fits M-LOK handguards and rail sections on other modern rifles.
What's included with the mount?
The product includes the rail itself. Hardware for attachment to M-LOK slots is standard and typically already part of your handguard or rail system; confirm compatibility with your specific setup.
How secure is this mount under recoil?
Seekins Precision manufactures to tight tolerances, and the anodized aluminum finish provides a secure grip in the M-LOK slots. Once locked in place with proper fastening hardware, it is designed to remain stable during shooting.
