Streamlight is now offering two rail mounted lights specific for rifles. The PROTAC Rail Mount 1 and the PROTAC Rail Mount 2 join an impressive catalog of products. The PROTAC Rail Mount series have a mount machined on to the main body of the light and include a pressure switch. The most interesting feature about the PROTAC Rail Mount series is the PROTAC Rail Mount 1, which features Streamlight’s Dual Fuel Design. The PROTAC Rail Mount 1 can take a CR123 battery or an Alkaline battery.

Streamlight PROTAC Rail Mount 1 and PROTAC Rail Mount 2. The PROTAC Rail Mount 1 can take CR123 batteries or Alkaline batteries.I like that the pressure switch is not one of those obnoxious bungee/phone cord types.

The PROTAC Rail Mount Series include both a pressure switch and tail cap. I got to handle both of these lights at the Streamlight booth and they appear to be well made. I have been running Stremlights on my rifles for several years, and I have never had a problem with a Streamlight flashlight. I predict these lights will do extremely well. If I purchased this light and were running the pressure switch, I would stash the tail cap in my pack, or in my pistol grip if possible. I have never had a problem with a pressure switch, but it is nice to build in some redundancy in a weapons platform.
