mpx-psb-3-imageSaint Petersburg, Fla. (Jan. 1, 2017) – SB Tactical™, inventors and manufacturers of the Pistol Stabilizing Brace™, is pleased to announce that the much-anticipated, 3-position adjustable MPX PSB™ brace is now shipping. Installation of one of the new adjustable braces does not change the classification of a pistol in accordance with GCA provisions.

“The term ‘game-changer’ is so overused it’s losing its impact, but the MPX PSB so dramatically improves the use of SIG MPX and SIG MCX pistols that it completely reinvents the term,” said Alex Bosco, inventor and CEO of SB Tactical. “We are both excited and proud to continue delivering innovative and useful products to the firearms community.”

The MPX PSB was designed exclusively for the SIG MPX™ and SIG MCX™ line of products. The MPX PSB has an MSRP of $249.99, weighs 19.13 ounces, is 8.0 inches in length, and has a max width of 2.25 inches.

The Bureau of Alcohol, Tobacco, Firearms, and Explosives (BATFE) approved the innovative, adjustable design of the new MPX PSB for PDW pistols in December of 2015, which encouraged SB Tactical to rapidly accelerate the development of this innovative product.
