TROY Industries 7" MRF Drop-In Carbine Rail – AR-15 Carbine

The TROY Industries 7-inch Modular Rail Float (MRF) Drop-In Carbine Rail replaces standard AR-15 carbine handguards with a free-floating rail system that improves accuracy by eliminating contact between the handguard and barrel. The two-piece clamp-on design installs without removing the front sight base or gas block, making it one of the fastest upgrades for shooters who want enhanced mounting options and improved precision without gunsmithing.

Machined from 6061-T6 aluminum with a hard-anodized black finish, this rail features four Picatinny rail sections at the 3, 6, and 9 o'clock positions for mounting lights, lasers, grips, and slings. The top rail co-witnesses with A2-height iron sights. Installation requires only basic tools—loosen the delta ring, remove factory handguards, and clamp the MRF rail sections around the barrel nut. Compatible with standard carbine-length gas systems and mil-spec delta rings.
