GRIDLOK® LITE 11" AR-15 Handguard
A one-piece, free-float design that brings GRIDLOK® innovation to a lighter, more cost-effective rail. The Patent Pending Quick Rail Detach system lets you remove the handguard in seconds—no tools—so you can access an adjustable gas block or install/remove a suppressor. The latch is updated with a locking button for even more secure closure.
Integrated at the front is a built-in flip-up BUIS, while M-LOK® slots at 3, 6, and 9 o’clock handle accessories. In back, an integrated 360° free-swivel QD socket supports a 2-point sling, and rear tabs with set screws help center the top rail to the upper for proper alignment. A forward cut accommodates suppressors up to 1.57" OD (necks to 1.42" ID after ~3"), and it plays perfectly with SI muzzle devices—including the OPPRESSOR—for a tucked look. The handguard is 6061-T6 aluminum; the barrel nut is 7000-series aluminum for high strength at low weight. This version is the 11" length.
