Magpul M-LOK ARCA / Dovetail Rails

Maximum rigidity between rifle and tripod—built for serious hunters

The Magpul M-LOK ARCA (Dovetail) Rails are one of our preferred solutions for hunters and precision shooters who demand the most rigid possible interface between their rifle and support systems. Designed around the ARCA-Swiss / dovetail standard, these rails provide a secure, repeatable connection to tripods, bipods, and most modern ball heads available today.

For tripod-based hunting—especially predator, varmint, and western-style spot-and-shoot setups—ARCA has become the gold standard. The Magpul system delivers that stability in a lightweight, durable, and field-proven package.

Why ARCA / Dovetail

The ARCA-Swiss (dovetail) interface offers major advantages over traditional picatinny adapters:

  • Full-length clamping surface for maximum rigidity

  • Excellent fore/aft balance adjustment on tripods

  • Rock-solid lockup under recoil

  • Compatible with most ARCA clamps and ball heads on the market

  • Ideal for tripod, bipod, and barricade-style support

For hunters seeking confidence in awkward field positions, this is the system we recommend.

Important Installation Disclaimer

Magpul supplies longer M-LOK mounting screws with these rails.
On rifles with very slim handguards and larger-profile barrels, these screws may contact the barrel if installed without checking clearance.

Recommended solutions:

  • Use shorter M-LOK screws, or

  • Trim the included screws to proper length

Always verify clearance before firing.
