Kevin Brittingham founded Advanced Armament Corporation in 1994 to manufacture sound suppressors, having previously been a distributor for GEMTECH, another suppressor manufacturer. [2] Under his direction, AAC grew to be one of the largest suppressor manufacturers in the U.S., including a number of small military contracts.
The High Standard HDM is a conventional blowback-operated semi-automatic pistol fitted with an integral silencer which decreases its report by more than 20 dB. [4] This pistol design was originally delivered on 20 January 1944, and original contract models were blued with a parkerized (phosphate) finish on the silencer.
The TEC-22 operates using a straight blow-back action. [6] The TEC-22 is constructed largely from molded plastic and stamped metal parts. The materials used, along with its extremely simple design allowed the gun to be made and marketed inexpensively. The TEC-22 is designed to use magazines and drums made for the popular Ruger 10/22 rifle. [7]
9×19mm Parabellum, a very popular caliber for suppressed shooting, can use almost any factory-loaded 147 grains (9.5 g) weight round to achieve subsonic performance. These 147gr weight bullets typically have a velocity of 900–980 feet per second (270–300 m/s), which is less than the 1,140 feet per second (350 m/s) speed of sound. [60]

An integral suppressor is featured on the K7, which leaves users the option to use standard 9mm Parabellum ammo instead of using subsonic ammo. [9] The K7's upper receiver is based on that of the K2, albeit slightly modified. [4] The hammer/fire control unit and telescopic stock are also derived from those of the K1. [4] [10]
A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. [1] Barrels with an integral muzzle brake are often said to be ported.
