Odin Works ARCA Flex M-LOK Sideways ARCA Rail

Most ARCA rails hang under the handguard and add a wide, sharp edged plank to the bottom of the rifle. The ARCA Flex turns the rail sideways and tucks it against the handguard, so the clamping surface sits closer to the bore and the profile stays narrow enough to grip comfortably.

It bolts to any M-LOK slot and gives an AR a proper ARCA interface for tripods and clamps, positioned near the balance point where a tripod actually wants to carry the gun. Edges are rounded rather than machined square, which matters when your support hand is wrapped around it for a long position. Aluminum construction keeps the added weight down.
