Battle Arms Development 13.7 Inch Rigidrail MLOK Handguard

Battle Arms Development’s proprietary RIGIDRAIL rail design provides the optimal balance between lightweight and strength/rigidity. The partial picatinny top rail perfectly matches the picatinny rail of the Battle Arms Development lightweight upper receiver. Made from aircraft grade 6061-T6 aluminum, the RIGIDRAIL is compatible with most low profile gas blocks and makes no contact with the gas tube.

It has a tapped hole at the front end for an optional bipod/sling attach point at the 6 o’clock position and is finished in a mil-spec type 3 class 2 hard-coat anodized. The RIGIDRAIL has 4 anti-rotation QD sling sockets – 2 at the front and 2 at the rear – at the 3 o’clock & 9 o’clock positions. It also has MLOK slots at 3, 6, 9, and partial 12 o’clock position with additional single MLOK slots at (4) 45 degree positions for forward mounting light, laser, etc.
