Midwest Industries SlimLine M-LOK - Free Float Handguard - 9.25"

The Midwest Industries Slim Line Free Float Handguard eliminates the inaccuracy and bulk of traditional two-piece rail systems for AR-15 owners who want better precision, a lighter build, and M-LOK accessory flexibility — all backed by a lifetime warranty and made entirely in the USA.

The Midwest Industries Slim Line is a 9.25-inch free-float M-LOK handguard for AR-15 platforms, machined from 6061 aluminum with a continuous Picatinny top rail, three-sided M-LOK attachment, and a single-piece design that slips over the included 4140 steel barrel nut without timing.

Free-float design eliminates the barrel contact that traditional two-piece rails impose, allowing the barrel to vibrate freely and consistently for improved accuracy. At 8.5 ounces installed, the single top rail and M-LOK-only sides keep weight low while leaving all three clock positions available for precisely placed accessories. Two integral anti-rotation QD sling swivel slots are built into the front and rear of the handguard, removing the need for separate QD mount adapters. The included 5-slot polymer M-LOK rail section lets you add Picatinny capability exactly where you need it. The 1.5-inch outer diameter and 1.3-inch inner diameter provide a slim, ergonomic profile in hand.

Compatible with all mil-spec forged upper receivers and the Midwest Industries billet upper receiver. Not compatible with piston AR gas systems. Includes barrel nut, barrel nut wrench, and 5-slot polymer M-LOK rail. 100% made in the USA.

Machined from 6061 aluminum with Type 3 hardcoat anodized finish. The 4140 heat-treated steel barrel nut is properly heat treated to handle the pressure and temperature of the 5.56 round through sustained use.

A strong choice for mid-length precision builds, lightweight duty rifles, and any AR-15 shooter upgrading from a standard handguard who wants improved accuracy and clean M-LOK accessory management backed by a lifetime guarantee.

Midwest Industries manufactures quality tactical accessories for AR-15, .308, Sig MCX, and AK-47 platforms, combining high-quality American materials with a lifetime warranty on every product.
