Area 419 ARCALOCK M-LOK Dovetail Rail 12″

Product Description

Precision-Engineered Control with the Area 419 ARCALOCK M-LOK Dovetail Rail

The Area 419 ARCALOCK M-LOK Dovetail Rail 12 pushes innovation by enhancing proven designs. As ARCA rails gain popularity in precision shooting, the need for a more secure system became clear. Friction-based rails often slip—especially when using a barricade stop under pressure.

That’s why Area 419 developed the ARCALOCK system—a mechanical locking dovetail rail that stays exactly where you need it.

Built for Precision, Milled for Strength

The Area 419 ARCALOCK M-LOK Dovetail Rail 12 is machined to the RRS 1.5″ dovetail standard, ensuring full compatibility with lever clamps. At just 4.1oz, it spans the entire forend—giving you maximum mounting flexibility without extra weight.

Lock-in Performance with the Area 419 ARCALOCK M-LOK Dovetail Rail 12

This 12″ rail features serrated sides that interface with Area 419’s proprietary clamp, locking it firmly in place. The serrations won’t damage your gear or hands but deliver rock-solid stability.

It’s also backward-compatible with standard ARCA accessories, though locking requires the Area 419 clamp.
