Streamlight ProTac Rail Mount 1LX PRO USB
Streamlight ProTac Rail Mount 1LX PRO USB
The Streamlight ProTac® Rail Mount 1L-X Pro USB is engineered for short-barreled rifles, carbines, and submachine guns where rail space is at a premium. Delivering 850 lumens and 30,000 candela with its rechargeable battery, this multi-fuel weapon light punches out a 346-meter beam for fast target identification, all in a low-profile package that leaves room for a pressure pad on tight rail setups.
The 1L-X Pro USB runs on Streamlight’s SL-B9 USB-C rechargeable battery or a single CR123A non-rechargeable battery, giving operators the flexibility to choose their power source in the field. Its rugged 6000-series machined aluminum housing with black anodized finish and impact-resistant BOROFLOAT glass lens stand up to hard use, while the integrated rail clamp allows quick, one-handed attachment to MIL-STD-1913 Picatinny or M-LOK-compatible rails.
Key Features:
850 Lumens / 30,000 Candela on High – Delivers a focused, far-reaching beam with a maximum range of 346 meters when powered by the SL-B9 battery.
Multi-Fuel Flexibility – Compatible with the rechargeable SL-B9 USB-C battery or a single CR123A non-rechargeable battery, so you’re never limited to one power source.
Jack-Cap® Tail Cap with Dual Activation – Offers push-button operation or remote pressure switch control for ultimate flexibility, with an integrated port that secures the remote switch.
TEN-TAP® Programming – Choose between High/Strobe, High Only, or Low/High operating modes to match mission needs.
Tool-Free Rail-Grip Clamp – Securely mounts to Picatinny rails or use the included M-LOK kit for alternative mounting on M-LOK-compatible systems.
Rugged Aluminum Build – 6000-series machined aircraft aluminum with anodized finish and BOROFLOAT glass lens for reliable, impact-resistant performance.
Why You’ll Love It – Whether you’re running a short-barreled rifle or carbine with limited rail space, the ProTac Rail Mount 1L-X Pro USB delivers serious 850-lumen output and dual-switch versatility without crowding your setup. Its rechargeable convenience, multi-fuel flexibility, and rugged, tool-free mounting make it built for operators who need reliable performance in a compact footprint.
