Area 419 ARCALOCK Rail MK22 for Barrett MRAD

Area 419 ARCALOCK Rail MK22

The ARCALOCK Rail represents a significant advancement in precision rifle accessory mounting. Engineered specifically for current-production Barrett MRAD MK22 rifles with M-Lok forends, this system delivers the mechanical locking reliability that serious shooters demand.

Key Features

Mechanical Locking System

• Serrated rail sides interface with Area 419's proprietary clamp design to create a positive mechanical lock
• Zero movement possible once secured
• Serrations are smooth and non-damaging to shooting bags and hands

Design & Compatibility

• Built to RRS 1.5" Dovetail Standard for universal lever clamp compatibility
• Backwards compatible with standard Arca accessories (though locking requires Area 419 clamps)
• Engineered to run the full length of the MK22 forend, stopping precisely at the handguard terminus
• Mounts at up to four attachment points for maximum rigidity and stability

Construction Quality

• Manufactured from 6061-T6 aluminum for optimal strength-to-weight ratio
• Type 3 hard-coat anodized in Flat Dark Earth for enhanced durability
• Every corner radiused and edge chamfered—a time-intensive process that reflects uncompromising build standards
• Made in-house in the USA from domestically sourced materials

Important Note: This rail is compatible only with current MK22/MRAD rifles featuring the M-Lok forend. Older rifles with circular mounting holes are not compatible.
