Description
The Area 419 Firearms ARCALOCK Fixed Barricade Block is a precision barricade stop engineered to give shooters a stable, repeatable contact point on Area 419’s ARCALOCK rail system. It was developed for use on the flat ARCALOCK rails, including the 12″ Universal, 14″, 8″, M-LOK, Keymod, and MPA compatibility rails.
The block is machined in-house from 6061-T6 aluminum and finished in a Type III black hardcoat anodize for long-term durability in the field. Standing 1-1/8″ tall from the bottom of the rail, the barricade features a grooved profile designed to aid in gripping the barricade surface during positional shooting. It uses a pinch clamp design along with a set screw to engage one of the ARCALOCK rail cuts, locking the stop securely in place.
A 3/32″ wrench is included and required to move the clamp. This component is built as a fixed barricade stop and is not designed to function as a moveable stop, giving precision rifle shooters a dedicated, repeatable barricade contact point for their ARCALOCK-equipped rifles.
