Frequently Asked Questions

How do you mount a Streamlight Protac Rail Mount HL-X on an AR-15 with an M-LOK handguard?

You'll need an M-LOK to Picatinny rail adapter. Attach the adapter to your M-LOK handguard, then mount the Streamlight Protac Rail Mount HL-X onto the adapter's Picatinny rail, positioning it flush with the handguard's end.

What is the best placement for a weapon light on an AR-15?

Position the light flush with the end of the handguard. This minimizes exposure to muzzle blast and carbon fouling, while ensuring the beam isn't obstructed by the barrel or handguard itself.

How should the pressure pad switch cable be managed on an AR-15?

Secure the cable along the rifle's rail using integrated mounting slots or zip ties. This prevents the cable from snagging on gear or the environment during operation.

The Streamlight Protac Rail Mount HL-X features both a standard push-button tail cap for constant on/off and a remote pressure switch for momentary activation and constant on/off.
