Seekins Precision 1560135F Ph3 / Element Arca Rail M-Lok

The Seekins Precision Ph3 / Element Arca Rail with M-Lok mounting is a precision accessory rail built for shooters who demand modular mounting flexibility. This Arca rail integrates both Arca-Swiss and M-Lok attachment standards, letting you run the full ecosystem of Arca-compatible accessories—tactical bags, clamps, monopods, shooting supports—while maintaining M-Lok real estate on your rifle or chassis. Whether you're setting up a precision rifle for long-range competition, a hunting platform for varied terrain, or a tactical build, this dual-standard approach eliminates the need to choose between mounting systems.

Seekins Precision has built a reputation for uncompromising quality in rifle systems and accessories, and this rail reflects that standard. The Ph3 / Element designation signals integration with their broader platform ecosystem, designed to work seamlessly with existing Seekins components or standalone on any M-Lok-compatible rifle. The Arca side opens you up to a mature, well-supported accessory network used across competition, hunting, and tactical applications.

This is a functional platform piece, not a cosmetic add-on. If your workflow involves swapping supports, bags, or Arca-mounted gear between shooting positions, or if you simply want to future-proof your rifle's mounting options, this rail delivers flexibility without compromise. Pair it with your existing M-Lok furniture and Arca accessories to build the exact rig you need.
