Seekins Precision ARCA Rail 3.3" M-LOK 6061-T6 Aluminum Black Anodized

The Seekins Precision ARCA Rail is part of the company's MRAS (Mounted Rail Attachment System) line — a compact 3.3" M-LOK mounting interface CNC-machined from 6061-T6 aluminum and finished in a tough black anodized coating. Designed to give shooters a strong, lightweight platform for ARCA-dovetail accessories, this section clamps directly onto any M-LOK-equipped handguard.

The MRAS uses a scalloped profile that trims overall weight without sacrificing rigidity, and integrated M-LOK slots along the rail body let you stack additional accessories onto the attachment itself. Whether you run a bipod, tripod, or shooting bag on a rigid ARCA clamp, this short, low-profile rail delivers a versatile mounting solution for the AR-15 and other M-LOK-equipped rifles.
