With the rapid growth in popularity of ARCA rails in precision rifle we saw a need to improve this great dovetail technology to 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 youve probably also seen it slide under much pressure.Introducing the ARCALOCK Dovetail Rail System Rail is only locking with an Area 419 clampRail Features: Serrated rail sides interface with our proprietary clamp design to mechanically lock it in place so no movement is possible.
