Knights Armament

Many manufacturers claim "mil-spec" standards.  Many more throw around words like "tested" or "proven."  None of them claim to be Knight's and none of them dare to compare themselves to the legendary NT-4.  If you have seen/heard/shot a suppressed firearm in the sandbox in the last decade, odds are good that it was an NT-4.  The NT-4 was originally built to exceed standards issued by USSOCOM. Through improved manufacturing methods and materials, Knight’s offered a more durable product that became the only suppressor to meet and exceed the government’s requirement of a 10,000+ round service life. There have been over 100,000 NT-4 Suppressors delivered to many different US Military Units worldwide.  Designed for use with 10.5” – 14.5” barrels in mind, the NT-4 delivers a 28 dB reduction and is only 6.5” in length. The quick detach gate latch is secured by a rotating locking ring to ensure the easy on / off feature still retains the suppressor securely.  The NT-4 attaches securely to either the included QD Flash Suppressor, or discontinued Triple Tap muzzle brake.
