Strong, Lightweight 6061-T6 Aluminum Construction
Seekins Precision is known for building parts that can stand up to real use, and this ARCA M-LOK rail is no exception.

The Type III black anodized finish helps protect against scratches, wear, and harsh weather conditions while maintaining a clean, professional appearance. Primary Arms+2Ammunition Depot+2
This combination makes the rail tough enough for match stages, training, and field use, yet light enough for long days behind the gun.
MRAS Design with Scalloped Profile
This rail is part of Seekins’ MRAS (Mounted Rail Attachment System), engineered specifically for shooters who demand precision and adaptability. EuroOptic+2RK Guns+2
The unique scalloped design reduces overall weight while maintaining stiffness, so the rail doesn’t flex under load from a bipod or tripod clamp. Seekins Precision+2Palmetto State Armory+2
The flat, stable surface provides a consistent, repeatable interface for ARCA-style clamps across the entire 8" length. EuroOptic+1
The result is a rail that feels purpose-built for modern positional shooting—clean, streamlined, and effective.

This dual-purpose design means you gain ARCA versatility while still keeping M-LOK real estate available for mission-specific accessories.
Note: For safety and reliability, always follow the manufacturer’s instructions and ensure all mounting hardware is properly tightened and checked regularly.
8" Length & 3.5-Slot Layout for Optimal Flexibility
At 8 inches long with 3.5 ARCA slots, this rail hits a sweet spot between stability and compactness: Primary Arms+1
Long enough to provide ample fore-aft travel for bipods and tripods, allowing you to fine-tune your rifle’s balance for prone, kneeling, or improvised positions.
Short enough to avoid excessive weight or overhang on lighter rifles or carbines.

For many shooters, 8" is the ideal length to cover the useful section of the handguard without overwhelming the front end.
