The Armaspec ARCA Rail, 12in Black (Armaspec part no. ARM621-12) integrates directly with an M-Lok handguard to give precision-rifle shooters a full 12 inches of ARCA-standard mounting surface. That’s enough real estate for a tripod head or other ARCA-Swiss-pattern accessory without hunting for the right spot, and the compact 0.70 by 2.50 inch cross-section keeps the rail low-profile on the handguard.
