Area 419 ARCALOCK Keymod Dovetail Rail Features The Area 419 ARCALOCK Keymod Dovetail Rail solves a real problem seen with standard ARCA dovetail rails which rely on friction alone and can slide under heavy barricade pressure. Serrated sides along the rail interface with an Area 419 clamp to mechanically lock the rail in place and those serrations are designed to avoid damaging bags or hands during use. The rail remains backwards compatible with standard ARCA accessories though it will only achieve the locking function when paired with an Area 419 clamp. Made to the RRS 1.5 inch dovetail standard it is built to work reliably with lever clamps already in a shooter s kit. At 12 inches long the rail covers the entire length of a typical stock forend giving shooters room to mount barricade stops and other accessories wherever needed. Despite its length the rail weighs only 4.1 ounces thanks to its 6061-T6 aluminum construction. Every corner is radiused and every edge chamfered during machining eliminating sharp edges that could snag gear or cause discomfort. Keymod attachment hardware is included and the rail is Type 3 hard coat anodized and made in the USA for added durability making it available for sale at GrabAGun for precision rifle shooters upgrading their ARCA setup.
