Area 419 Arcalock Clamp w/ Barricade Stop

Introducing the ARCALOCK Dovetail Rail Clamp w/ Barricade Stop

Area 419 is always looking for ways to improve existing products, and has once again set the bar with the new Arcalock system. They saw the need to improve on the existing dovetail ARCA rails with something that could be mechanically locked in place instead of just friction. If you have ever tried using a Barricade stop on an existing ARCA rail, you’ve probably also seen it slide under much pressure. (Arcalock rail and bipod not included)

Clamp Features:

• Proprietary two-stage screw design.
• 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.
• ~1/4 Turn releases the clamp from the detents on the ARCALOCK rail for movement
• One Turn releases clamp to be removed from rail
• Clamp directly bolts to Atlas Bipods using their factory hardware
• This Clamp with Barricade stop is NOT compatible with Harris Bipods.
• The Clamp with Barricade stop for Harris Bipods can be found here.
• Harris Bipod adapter with no Barricade stop can be found here.
• Picatinny rail adapter that can be bolted to the clamp for use with other bipods can be found here.
• 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
• Knob/Screw design prevents the clamp from being able to fall apart if you loosen it too far
• 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
