The WORKHORSE® M-LOK® Rail System is built for shooters who demand a slim, lightweight, and functional handguard without unnecessary bulk. Precision-machined from 6061-T6 aluminum and finished with a Type III black hardcoat anodizing, this freefloat rail is rugged enough for duty use while remaining lightweight for optimal handling.

Designed with M-LOK® attachment slots at the 3, 6, and 9 o’clock positions, plus skeletonized cutouts to reduce weight, the WORKHORSE® strikes the perfect balance of strength and agility. A continuous 1913 Picatinny top rail at 12 o’clock is notch-cut to align seamlessly with upper receivers, further shaving ounces without sacrificing mounting capability.

At just 7.5 oz (9.6 oz with barrel nut) and an internal diameter of 1.36”, this 13″ rail provides ample clearance for low-profile gas blocks and is ready to accept your favorite optics, lights, and accessories.
