American Built Arms LTF Picatinny Rail Combo Pack, Black

The American Built Arms Company LTF Rail Combo Pack (brand part no. ABALTFCR) gives AR-15 builders three Picatinny rail sections in one affordable kit — a 4-slot, a 5-slot, and a 7-slot rail — all molded from lightweight black polymer. ABA integrates the mounting hardware directly into each rail section, so there is no separate hardware to hunt down, and the included fasteners are sized for any standard mil-spec M4 upper. The rails are built to work with ABA M-LOK handguards as well as other M-LOK-pattern forends, letting shooters bolt on lights, foregrips, or sling mounts exactly where they are needed. Each section installs from inside the handguard outward, keeping the exterior profile clean once it is in place. It is a simple, budget-friendly way to add rail real estate to a carbine built for the range, home defense, or duty carry.
