Area 419 ARCALOCK Rail for Barrett MRAD MK22

Description

The Area 419 ARCALOCK Rail is a dovetail rail system engineered for current-production Barrett MRAD/MK22 rifles that use the M-LOK forend. It provides a full-length Arca-style interface along the top of the forend and is machined with radiused corners and chamfered edges for safe handling. The rail is designed to mechanically lock when used with Area 419’s proprietary clamp and is backwards compatible with standard Arca accessories when a clamp is not utilized. Construction emphasizes strength and durability for demanding range and field use.
