Overview
The Streamlight ProTac Railmount HL-X USB is a high-output flashlight designed for tactical applications, delivering 1000 lumens of bright light. This level of output allows for effective illumination in low-light conditions, making it easier to identify targets and navigate your surroundings. Builders often integrate this powerful light into mid-length gas system AR-15 builds chambered in 5.56 NATO, where versatility and performance are key considerations.

Build history on GunPartPicker
Builders have been adding the Streamlight ProTac Railmount HL-X USB - 1000 Lumens to their builds on GunPartPicker since January 2026. All time, it ranks #23 of the 204 weapon lights builders have added. Builds with this weapon light are mostly chambered in 5.56 NATO (67%, then 300 Blackout 33%), split between carbine-length (33%) and mid-length (33%) gas systems, and nearly all AR-15.
Availability is good: it was in stock at one retailer or another nearly every day in August 2026, and today all 8 retailers we track have it in stock. Prices barely moved in August 2026, holding around $140.79, so there haven't been real sales lately. Buying today, the lowest price is $135.99 at BattleHawk Armory, which matches the best price we saw in August.
