Midwest Industries Combat Rail T-Series Free Float Handguard 9.25" MI-CRT9.25

The Midwest Industries Combat Rail T-Series Free Float Handguard 9.25" is a precision-engineered rail system built for AR-platform shooters who demand a clean, modular setup without the bulk of fixed furniture. This 9.25-inch free float design isolates your barrel from flex and torque, letting it naturally vibrate without interference—a proven way to improve consistency at the range or in the field. The Combat Rail's monolithic top rail runs the full length of the handguard, giving you that seamless look and uninterrupted Picatinny real estate for optics, lights, and other mission-critical accessories.

Built from 6061 aluminum and hard-coat anodized to MIL-STD 1913 specs, this handguard is made to last through years of hard use. The T-marked rail system clearly indicates where standard mounts will land, eliminating guesswork during setup. A patented 4140 heat-treated torque plate and barrel nut (included with wrench) ensure a secure, repeatable fit, while two integral QD sling sockets keep your carry options flexible. Every edge is fully dehorned and deburred for comfort—no sharp surprises when you're running drills or settling in for a long day of shooting. The 9.25" length strikes a practical balance between maneuverability and rail length, weighing just 11.4 ounces and fitting handily in most shooting situations.

This is USA-made gear backed by Midwest Industries' lifetime warranty. Note that free float handguards work on standard forged AR-15 upper receivers; if you're running a billet upper, confirm compatibility with your receiver manufacturer before ordering. Not compatible with piston-driven AR platforms.

Frequently Asked Questions

Will this handguard fit my AR upper receiver?

The Midwest Industries Combat Rail is compatible with standard forged AR-15 upper receivers. If you're using a billet upper, contact your billet receiver manufacturer to verify fitment before purchasing, as billet uppers vary in dimensions. This handguard is not compatible with gas piston AR platforms.

What's included in the box?

The handguard comes with a 4140 heat-treated barrel nut and the wrench needed to install it. Optional titanium barrel nut and titanium clamp screws are available for separate purchase if you want to upgrade.

How does free float improve my shooting?

Free float design allows your barrel to vibrate naturally without contact from the handguard, reducing the variables that affect bullet impact and helping deliver more consistent groups—especially useful if you're dialing in a precision rifle or running high-round-count training sessions.

Can I mount accessories and lights to this rail?

Yes. The full-length monolithic Picatinny rail is T-marked to show standard accessory spacing, making it straightforward to mount optics, lights, vertical grips, and other MIL-STD 1913-compatible gear wherever you need them.
