Area 419's Arcalock 6" M-LOK rail features serrated sides that mechanically lock with proprietary clamps for zero movement. Weighs just 2.2oz, made from 6061-T6 aluminum, Type 3 hard coat anodized, and includes all mounting hardware.
The Arcalock represents a thoughtful approach to precision accessory mounting. Rather than relying solely on friction or clamping force, Area 419 engineered serrated rail sides that interface with their proprietary clamp design to create a mechanical lock—eliminating movement entirely.
This is precision equipment built with the attention to detail that serious shooters expect.
