[SHOT 2016] Streamlight PROTAC Rail Mount lights

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.


Key Features of the PROTAC Rail Mount 2 include;

  • Runs on 2 CR123 batteries
  • Weighs 5 ounces
  • High setting is 625 lumens for 1 hour and 30 minutes
  • Low setting if 60 lumens for 18 hours
  • Strobe setting runs for 2.75 hours.
  • Light is TEN-TAP programmable.

Key Features of the PROTAC Rail Mount 1 include;

  • Features Streamlight’s DUAL FUEL Design. The PROTAC Rail Mount 1 Runs on 1 CR123 battery OR 1 AA Alkaline battery.
  • Weighs 4.3 ounces
  • High setting is 350 lumens for 1 hour and 45 minutes
  • Low setting if 40 lumens for 14 hours 30 minutes
  • If AA Alkaline battery is used, 150 lumens for 1 hour 30 minutes and 40 lumens for 8 hours.
  • Strobe Setting isĀ  2.75 hours for both battery types.
  • Light is TEN-TAP programmable.

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.

    How are the tape switches secured to the rail? I’ve only had experience using Velcro and it was less than favorable.

      Looks like the switch fits between to end pieces that attach to the rail in the normal way.

        :0 Thanks, I’m so far behind the times it seems.

        • TheNotoriousIUD

          Just a guess but it looks like a good set up.

    I’m curious what pricing will be, as I don’t see any listed for sale yet. However, 1/3rd of the price of the nearest Surefire equivalent is probably a good bet.

      Has to be. Streamlight typically falls in that range anyway.

  • Curious Georgian

    And what rail are they displayed on?

  • Wingbert

    Don’t need low setting, dont need strobe. Streamlight would need to be really agressive on their pricing for me to choose it over surefire.
