Frequently Asked Questions

Which firearms and rail types is the ProTac Rail Mount 2L compatible with?

The Streamlight ProTac Rail Mount 2L is designed to mount securely on any Picatinny or MIL-STD-1913 rail system. This makes it compatible with a wide range of platforms including AR-15/M4-style rifles, carbines, and many modern shotguns equipped with a rail. It is not designed for use with Weaver-style rails without an adapter, so verify your firearm's rail specification before purchasing.

What batteries does the ProTac Rail Mount 2L use, and how long do they last?

This weapon light is powered by two CR123A lithium batteries, which are widely available and deliver reliable performance across a broad temperature range — ideal for field and duty use. On the highest 625-lumen setting, you can expect approximately 1.5 hours of runtime. Switching to the 40-lumen low mode extends runtime to roughly 19 hours. Streamlight recommends using high-quality lithium batteries for best performance and longest shelf life.

Can I use a remote pressure switch with the ProTac Rail Mount 2L?

Yes. The Streamlight ProTac Rail Mount 2L is compatible with Streamlight's remote pressure switch accessories, which allow for momentary-on or constant-on activation without repositioning your firing grip. This is especially useful for AR-platform builds and other long guns where ergonomic light activation is critical. The remote switch is sold separately — check with Goodland Guns for compatible Streamlight remote switch options.
