I can’t think of a special operations organization, whether military or law enforcement who is unfamiliar with the Knight’s Armament Company
(KAC) of Titusville, FL. The company enjoys an excellent global reputation.
KAC is owned by C. Reed Knight and was founded in 1982. It is a well diversified manufacturer of firearms and accessories. KAC’s accessory portfolio consists of the Rail Interface System (RIS), Rail Adapter System (RAS), vertical grips, rail panels, front and rear sights, suppressors and clip-on night vision devices marketed as the Universal Night Sight (UNS). Their firearm portfolio consists of the SR-15, SR-16, SR-25, M110 Semi-Automatic Sniper System (SASS), Personal Defense Weapon (PDW), SR-47 and SR-50 (no longer in production), M203 and Master Key, Stoner LMG and ChainSAW LMG. Along with the listed products, KAC, has produced special application products for a number of customers.
KAC’s success stems from the company’s ability to respond to any requirement and a commitment to design and manufacturing elegance. All KAC weapon designs incorporate sound suppression from inception and no modifications to the weapon are needed.
KAC designed a number of sound suppressors but they are best known for the MK23 .45 Caliber Suppressor. The device was specifically designed by KAC for the Heckler and Kock MK23 Mod 0, .45 ACP, adopted by USSOCOM. U.S. Special Operations Command took delivery of the first units in 1996.
- MK23 Suppressor
The Mk23 suppressor was designed to be fired wet and provides the best sound attenuation when fired wet (38dB of attenuation wet v. 28 dB attenuation dry), by a factor of 10dB. The company continues to manufacture the MK23 suppressor. It is available in the supply system under NSN 1005-01-435-1917.
KAC also manufactures the H&K USP-T .45 Caliber Suppressor, P/N 97225, for the H&K USP Tactical. Like
KAC H&K USP-T .45 Caliber Suppressor
the Mk23, this suppressor is designed to be fired wet and delivers 38dB of attenuation when fired wet compared to 28dB when fired dry; resulting in a 10db gain. Firing the HK USP-T wet is the recommended use.
Unlike the Mk23 suppressor, the H&K USP-T uses a Nielsen device so that it functions reliably in a Browning style action, like the one found on the H&K USP Tactical. KAC also manufactures rifle caliber suppressors.
The M4/M16 QDSS-NT4 Suppressor is their 5.56 x 45 offering. It is a quick attach design that mounts directly to the KAC flash suppressor.
KAC Flash Suppressor and Quick Attach - Detach Mount
KAC M4/M16 QDSS-NT4 Suppressor
It will attach to any M4 or M16 equipped with the Knight’s flash suppressor. KAC includes the flash suppressor with the M4/M16 QDSS-NT4. The suppressor is designed to be fired dry and delivers 28db of attenuation. The M4/M16 QDSS-NT4 is rated for full automatic fire.
Knight’s Armament Company also produces suppressors for their line of 7.62 x 51 weapon platforms; more notably the KAC SR-25, still in use by USSOCOM as a sniper platform, and the M110 SASS, in use by the U.S. Army as the standard issue sniper platform.
- KAC MK11 Mod 0 7.62 x 51 Suppressor
The Mk11 Mod 0 uses a quick attach / detach mount and delivers 28 dB of attenuation. The tube measures 12.25″ in length and 1.375″ in diameter, and its available through the supply system under NSN: 1005-01-474-0197. The M110 suppressor, NSN: 1005-01-542-4487 is identical to the Mk11 Mod 0 differing only in tube length. The M110 measures 14.125″.
Every Knight’s Armament Suppressor is a no frills industrial strength product designed for military operations and all of their suppressors are currently in active military use.
