Area 419 ARCALOCK 12in Universal Barricade Rail Kit Black. 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. These positions are engraved on the rail so you can easily adjust for known objects.
