O.k., we’re back. Sorry for the delay, but DefenseReview’s (DR) been on travel, and we’ve been dealing with some stuff. However, now that we’re back, we’re going to try to get back into publishing content fairly regularly, primarily in the form of videos, starting with this one on the new Knight’s Armament Company (KAC) KS-1 tactical AR-15 rifle/carbine/SBR (Short Barreled Rifle) and 3D-printed PRT reduced-back-pressure suppressor.

The new KAC KS-1/suppressor combo looks pretty fantastic, and is military-grade, so it’s definitely worth watching the video we shot at SHOT (SHOT Show 2024), below. We’d like to thank Trey Knight for taking the time with us at the KAC booth. We appreciate it.

KAC KS-1 Specifications:

Barrel: 13.7″ (34.8cm) 1:7 Twist
Caliber: 5.56mm
Weight: 6.88 lbs (3.12kg)
Length: 32.2″ (81.8cm) to 34.2″ (86.9cm)

Editor’s Note: Defense Review doesn’t yet know when KAC will offer a semi-auto-only KS-1 variant in limited numbers commercially, or whether it will also offer a semi-auto-only KS-2 variant commercially in limited numbers. We’ll try to fin out.
