Midwest Industries Slim Line M-LOK - Free Float Handguard - 10.25"

The Midwest Industries Slim Line M-LOK AR-15 Free Float Handguard at 10.25" delivers free float accuracy benefits and M-LOK accessory compatibility in one of the slimmest, most ergonomic profiles available for the AR-15. Built for shooters who find quad rail designs uncomfortable and want a single-rail handguard that cuts weight and improves handling, this free float design replaces the top-heavy feel of older rail systems with a rounded, comfortable grip.

The Slim Line M-LOK AR-15 Free Float Handguard is a free float handguard designed for AR-15 builds that prioritize a slim, comfortable profile with a single Picatinny top rail and three sides of M-LOK for selective accessory placement.

The single Picatinny top rail removes the unnecessary weight of unused side and bottom rails while keeping the full-length MIL-STD 1913 surface for optics and sights. Three sides of M-LOK allow accessories to be mounted where actually needed, and an included 5-slot polymer M-LOK rail section adds a Picatinny segment at any position. The rounded profile makes the handguard noticeably more comfortable to hold compared to angular quad-rail designs. At 9 oz installed with a 1.5" outside diameter and 1.3" inside diameter, the Slim Line keeps the rifle front end light. Two integral anti-rotation QD sling sockets are built into the handguard for direct sling attachment.

Compatible with all Mil-Spec forged upper receivers and the Midwest Industries Billet upper receiver. Not compatible with piston AR gas systems. The handguard slips over the barrel nut without threading on, keeping it flush-fit to the upper receiver. Includes the 4140 heat-treated barrel nut, wrench, and torque plate. Overall length: 10.5". Installed weight: 9 oz.

Made from 6061 aluminum with a Type 3 hardcoat anodized finish. 100% made in the USA. Backed by the Midwest Industries lifetime warranty.

An effective choice for AR-15 builds where comfort, reduced weight, and selective M-LOK accessory mounting are priorities over full quad-rail coverage.
