The Strike Industries Gridlok Lite 11" rail for AR-15 delivers field-proven modularity without the weight penalty or the price tag of its full-size counterpart. Built on the same patent-pending Quick Rail Detach system, this one-piece handguard strips off in seconds—no tools required—making it a game-changer when you need to service a suppressor, adjust an adjustable gas block, or swap components at the range or in the field. If you run a modern tactical AR and value working on your gun without a trip back to the gunsmith, this is the handguard that gets out of your way.
The Gridlok Lite starts with a solid foundation: 6061-T6 aluminum construction keeps weight down while the 7000 series aluminum barrel nut delivers the strength you need for a rock-solid mount. The front of the rail features an integrated flip-up backup iron sight—one less thing to buy—and a suppressor-friendly cut designed to accommodate suppressors up to 1.57" in diameter, including Strike Industries muzzle devices. The rear houses a 360° free-swivel QD socket for two-point sling attachment, and alignment tabs with set screws ensure the top rail seats square to your upper receiver every time.
Accessory mounting follows M-LOK slots at 1, 3, 5, 6, 7, 9, and 11 o'clock positions, giving you the same layout flexibility as heavier rails. The redesigned QD latch includes a new locking button for faster engagement. If you're building a lightweight AR, running suppressors, or just sick of dealing with handguards that require a full teardown to service, the Gridlok Lite 11" delivers practicality and reliability in a compact package.

Frequently Asked Questions
What AR-15 uppers is the Gridlok Lite 11" compatible with?
The rail is designed for Mil-Spec M4 upper receivers. It is not compatible with piston gas blocks, some billet or side-charging uppers, and 11", 15", or 17" models with an A2 front sight post gas block. If you're unsure about your upper, reach out and we'll help you verify.
Can I remove the handguard without tools?
Yes. The Quick Rail Detach system lets you push and pull the QD latch to strip the handguard in seconds—no tools, no teardown. This makes field adjustments, suppressor swaps, and gas block tweaks quick and painless.
Will this rail fit my suppressor?
The front cut is designed for suppressors up to 1.57" in diameter, including all Strike Industries muzzle devices. If your suppressor is larger or you want to confirm fit before ordering, let us know the specs and we'll point you in the right direction.
What's included with the Gridlok Lite 11"?
