The Midwest Industries 14-inch T-Series Combat Rail is a free-float quad-rail handguard for AR-15 platform rifles. Full-length M1913 Picatinny rails on all four sides - top, bottom, and both sides - give you maximum mounting real estate for lights, lasers, optics, foregrips, and bipods on a single platform. T-marked rails number each Picatinny slot so you can record exact accessory positions and reproduce the setup after teardown - useful if you swap optics between rifles. The handguard is dehorned and deburred end-to-end for comfort against a bare hand. Features: 14" length, free-float design (no barrel contact) Mil-Spec M1913 Picatinny quad rail - top, bottom, both sides T-marked rails for repeatable accessory placement Two anti-rotation QD sling swivel sockets Dehorned and deburred for bare-hand comfort Includes barrel nut, torque plate, and barrel nut wrench Made in the USA by Midwest Industries. Confirm your gas system length (mid or rifle) clears the 14-inch profile and that your barrel nut threads are standard AR-15 spec before installing.
