Utg Pro 4/15 Carb Quad Rail W/Ext Bk

The UTG Pro 4/15 carbine quad rail is a drop-in handguard upgrade for AR platform rifles that need serious accessory real estate. If you're running a piston-driven 4/15 carbine or any AR with rails extending past the front sight, this extended quad rail swaps in fast and gives you multiple attachment points for lights, lasers, grips, and backup optics—all without the bulk of a full-length rifle rail system.

Built with a solid locking feature to keep it rock-solid once mounted, the quad rail design delivers Picatinny-compatible rail space on all four sides of the handguard. You get 19 slots on top, 23 on the bottom, and 25 each on the left and right—plenty of options for mounting your mission-specific gear. The black finish blends seamlessly with most carbine builds and holds up to field use.

The rail ships with 18 UTG rubber rail guards included, so you can immediately protect your rail surfaces and improve grip without spending extra on aftermarket covers. Drop-in installation means no permanent modifications to your receiver—you can swap it out when your setup needs change. Whether you're building a tactical carbine, setting up for three-gun, or just want modular flexibility on your 4/15, this handguard puts the accessory mounting options in your hands.
