The AREA 419 419-ALK-UNIV4RAIL ARCALOCK 4″ Flat is the lightest and smallest ARCALOCK rail on the market, weighing just 1.5oz and designed to fit forend hole spacings of 2″-3.5″. Made from 6061 billet aluminum with black hardcoat anodized finish, this compact rail brings Area 419’s innovative mechanical locking technology to rifles and chassis configurations where space is limited. Serrated rail sides interface with Area 419’s proprietary clamp design to mechanically lock the rail in place so no movement is possible, eliminating the slippage issues common with friction-based ARCA systems.
The rail comes with t-nuts and hardware to allow installation closer to the magwell for tripod use, giving shooters flexibility for bipod, tripod, or bag rest configurations. Area 419 designed the ARCALOCK system to address the growing popularity of ARCA rails in precision rifle while improving the dovetail technology with mechanical locking instead of just friction. Whether mounted on a hunting rifle, precision shooting platform, or small-frame chassis, the ARCALOCK 4″ Flat delivers rock-solid performance in a minimal footprint.
