[SHOT 2016 Range Day] Fabryka Broni MSBS 556K

    Though I didn’t get to shoot the fabled bullpup version of the FB MSBS 556, I did get to shoot the FB MSBS 556K at SHOT 2016 Range Day. Drawing largely from the Magpul Masada, the version of the FB MSBS 556 that I got to shoot was the conventional model, or K model. With an EoTech red dot, I was able to hit steel targets out to 200 yards with ease. My reloads were slightly faster then with a standard Ar-15, however, if I was using a Magpul B.A.D lever equipped Ar-15, my reloads would be identical in speed.


    The MSBS 556 K features a folding, adjustable stock. Note the handguard.

    MSBS 556 K. Note the ambi controls. The ejection port can be switched to the left or right side depending on if the shooter is left or right handed.

    Talking to the company representative, I inquired about the availability for the United States market. The representative told me that “they were still about a year out”. Farbryka Broni will be at booth 1907. I always liked the idea of the Magpul Masada. It is neat to see the design still in development and use. I look forward to the day when these are available in the United States.


    Fabryka Broni had their Mod. 96 Mini-Beryl Automatic Carbine available. Fun gun to shoot. Very accurate.
