Area 419 ARCALOCK Dovetail Rail for Barrett MRAD/MK22

The Area 419 ARCALOCK Dovetail Rail (Area 419 part no. 419-ALK-MK22) is a purpose-built rail system for current-production Barrett MRAD and MK22 sniper rifles with the M-LOK forend. Rather than relying on generic clamp-on hardware, the ARCALOCK uses serrated rail sides that mechanically lock into a matching Area 419 clamp, eliminating the shifting and slop that can throw off a precision hold on a barricade or bag. It runs the full length of the MRAD forend and attaches at up to four points for a rock-solid interface between rifle and rest, making it a natural upgrade for long-range and PRS-style shooters who depend on a completely stable platform.

Key Specifications

• Built for current-production Barrett MRAD/MK22 rifles with the M-LOK forend; older circular-hole forends are not compatible.
• Serrated rail sides mechanically lock into an Area 419 clamp so no movement is possible once secured.
• Runs the full length of the MRAD forend, stopping at the end of the handguard for maximum contact area.
• Backward compatible with standard Arca-style accessories, though it only locks in place with an Area 419 clamp.
• Machined to the 1.5-inch RRS dovetail standard so lever clamps fit as expected.
• Every edge is chamfered and radiused on the machine, leaving no sharp corners to damage gear or hands.
• Attaches to the rifle at up to 4 points for added strength and stability.
• Finished in Type III hardcoat anodized FDE over 6061-T6 aluminum, made in-house in the USA.
