Controls are familiar and straightforward, with a manual safety selector and STANAG magazine interface.
The 16-inch barrel is made from Cr-Mo-V steel, chrome-lined for durability, and cut in the M4 profile with an M203 step. It is HP/MPI tested and marked accordingly, with a 1:7 RH twist. The barrel is threaded and fitted with an A2 birdcage flash suppressor, and the bayonet lug is present.

Magpul MOE furniture, including the stock and pistol grip, rounds out a practical, duty-oriented setup.
