The Bureau of Alcohol, Tobacco, Firearms and Explosives has approved the design of SB Tactical's new adjustable Pistol Stabilizing Brace. The new braces are ideal for PDW pistol platforms, including the SIG MPX pistol.

According to the ATF letter, installation of the brace will not change the classification of the pistol in accordance with GCA provisions. SB Tactical has accelerated the development of two adjustable brace models, the MPX PSB and SBPDW.

The SBPDW is designed solely for the AR pistol platform. It weighs 18.14 ounces, is 5.5 inches in length, and has a maximum width of 2.25 inches. The MPX PSB is designed exclusively for the SIG SAUER SIG MPX and MIG MCX line of products. It weights 19.13 ounces, is 8 inches in length and has a mimum width of 2.25 inches.

Both products were displayed at the NRA Annual Meeting in Kentucky. SB Tactical will begin shipping out the new adjustable brace models this summer.
