Dovetail Technology for Atlas and Harris Bipods

The Area 419 Arcalock Clamp for the Atlas and Harris Bipods feature a proprietary two-stage screw design. This clamp works on all standard Arca/1.5” Dovetail Rails. The clamping screw features two different thread pitches.

The coarse 16tpi is used when no tension is on clamp, allowing rapid movement of the clamp vs others on the market. With high speed comes low torque though, so to counteract this as soon as the clamp sees tension it will switch to the 32tpi threads in the knob to give you extra torque when not using on an ARCALOCK rail.

  • Clamp and knob machined in house from 6061-T6 Aluminum
  • Screw is turned from 303 Stainless Steel
  • Type III Hardcoat Black anodized clamp and Gold anodized knob

A 1/4 turn releases the clamp from the detents on the ARCALOCK rail for movement. One turn releases clamp to be removed from rail. The clamp directly bolts to Atlas Bipods using their factory hardware. The barricade stop can either be standalone on the clamp using provided hardware, or sandwiched between an Atlas bipod (Barricade stop does not work with Harris Bipods). The clamp is backwards compatible with standard ARCA rails by removing the two pins, and will still work this way to give you infinite sliding adjustment on the ARCALOCK rail. Moving side of clamp is dovetailed on both sides to prevent tilt.
