Area 419 ARCALOCK Fixed Barricade Stop Features The Area 419 ARCALOCK Fixed Barricade Stop is machined in house from 6061-T6 aluminum and finished with a Type III black hardcoat anodized coating for long term wear resistance. It slides onto flat ARCALOCK rails such as the 12 inch Universal M-LOK Keymod and MPA patterns from the end of the rail rather than clamping over it. A pinch clamp design works together with a set screw that engages one of the ARCALOCK cuts guaranteeing the stop will not slip once it is set. Grooves machined into the body aid in gripping the barricade during hard positional or barricade shooting. A 3/32 wrench is included and required to move the clamp since the stop is intentionally not designed to be repositioned on the fly mid stage. Once locked in place it stands 1-1/8 inches tall from the bottom of the rail giving a consistent and repeatable reference point for barricade support. Its compact footprint keeps added bulk to a minimum while still providing a secure hard stop for the shooting hand or support arm. This fixed stop is well suited for precision rifle competitors and barricade shooters who need a dependable no slip rail accessory for sale at GrabAGun.
