Midwest Industries Combat Rail T-Series One Piece Handguard - 15" Free Float M-LOK Handguard

The Midwest Industries Combat Rail T-Series One Piece Handguard is a 15-inch free float M-LOK handguard built for shooters who demand a lightweight, modular platform without compromise. Whether you're building a precision rifle, running drills at the range, or setting up a carbine for duty use, this monolithic rail system gives you the real estate and mounting flexibility to dial in your perfect setup. The one-piece design eliminates the typical gap between handguard and upper receiver, creating a seamless aesthetic while maintaining the rigidity serious shooters expect.

Machined from 6061 aluminum with a Type 3 hard coat anodize, the Combat Rail handles the abuse of tactical training, competition, and field use. The 15-inch length strikes a balance—long enough to accommodate optics, lights, lasers, and backup sights with room to spare, yet manageable in tight shooting positions. A full-length MIL-STD 1913 Picatinny rail runs the top, T-marked for quick accessory placement, while M-LOK slots on the sides and bottom let you attach gear exactly where you need it. Two integral QD sling sockets are positioned for fast cinch-up with single-point or two-point sling setups.

The barrel nut is 4140 heat-treated steel with a patented torque plate design—hardware that comes in the box along with the wrench you'll need for installation. Fully dehorned and deburred edges mean no sharp surprises during handling. At 17.0 ounces installed, it keeps your rifle's weight down without feeling hollow. Optional titanium barrel nut and clamp screws are available if you want to drop weight further. All Combat Rail handguards are made in the USA and backed by Midwest Industries' lifetime warranty.

A note on fit: This handguard is engineered for standard forged upper receivers. If you're running a billet upper, contact your receiver manufacturer to verify compatibility—billet dimensions vary. Not compatible with gas piston AR platforms.
