Overview
This 13-inch Reptilia ARCA-S puts the ARCA tripod interface on the handguard itself. Reptilia machines a 2.8-inch ARCA section into the rear of the rail, right where it meets the upper receiver, so a tripod head locks to the rifle without an M-LOK ARCA plate hanging off the bottom.
The mount is Reptilia's patented turnbuckle on a standard M4 upper. Torque the barrel nut to 50 ft-lbs, then snug the turnbuckle by hand with red thread locker. M-LOK still runs the rest of the rail for lights, grips, and bipods. The 13-inch black rail weighs 377 g, about 13.3 ounces, in machined aluminum.
The ARCA section lives only at the receiver junction, so fore-aft tripod placement is fixed there. The matching FDE rail is the same 13-inch part in a different finish. Reptilia has not released the 11.5-inch length. The barrel-nut and turnbuckle wrench is a separate tool.
