Serrations are not sharp, will not damage bags or your hands. – Rail is backwards compatible with standard Arca accessories, but will not be locking without our clamp – Rail is specifically built to run the full length of a new Barrett MRAD forend, stopping right at the end of the handguard. – Made to the RRS 1.5? Dovetail Standard, so you can be sure lever clamps will work – No sharp edges. Every corner is radiused, and every edge is chamfered on the machine.
