KAC-Knight’s Armament KS3 Series Rifle

The KS-series of carbines is the next step in Knight’s continued refinement of the AR-15 platform. Improvements have been made to ergonomics, maintenance procedures, and function. The self-indexing, highly efficient Mod 2 gas system has been retained in this latest iteration. The straight gas tube design and an “AN”-type fitting minimizes gas pressure loss between the gas block and the carrier key, and is easily removed and replaced in case of damage or wear. The gas block is held in place with a nut threaded to the barrel, simplifying removal and re-installation without the need to alter the barrel to allow fitment of taper-pins or set screws. The risk of misaligning the gas block with the gas port is eliminated by physical features which ensure that the parts are in proper position during assembly. Also continuing forward are the Quick Detach Coupling (QDC) compatible flash hiders, our exceptionally durable 1 in 7” twist cold hammer forged barrels, our Drop-In 2-Stage Match trigger, and KAC 200-600m micro flip-up front and rear sights. The left-side magazine release button retains its position and protective fencing, with a reduced profile to prevent unintended magazine release. The KS-Series are available in 4 barrel length configurations, each optimized to meet various needs and requirements. Each configuration has been built to exceed stated requirements, suppressed and unsuppressed, across environmental and performance spectrums.

KS-3
Barrel – 11.5″ (29.21cm) 1:7 twist
Caliber – 5.56mm
Weight – 6.1 lbs (2.79kg)
Length – 30″ (76.2cm) to 32″ (81.28cm)

The KS-3 features a standard profile 11.5” (292mm) cold hammer forged barrel, with an optimal length for those that need a small rifle-caliber carbine. It is easy to stow for transport, unobtrusive to carry, and highly efficient in use. With nearly 100% compatibility with the other KS rifles, it is the recommended choice for a secondary upper receiver for those with KS-1 or KS-2 rifles, or as a primary system for those that require a dependable, small, light carbine.

URX6 Handguard
The URX6 is a self-indexing, highly shift-resistant handguard with a full-length 12:00 MIL-STD 1913 interface rail as well as 7-sides of M-LOK negative-space mounting slots. This handguard slides over the attached barrel nut, aligned by an anti-rotation index tab and slot feature contained in the top rail of the upper receiver. The anti-rotation and alignment features are stream-lined and unobtrusive, with no external snag or catch
points. The handguard is affixed with a retention nut that creates significant load to the attachment point of the handguard, making the handguard extremely resistant to shift caused by impact.

E3.2 Bolt
The KAC E3.2 bolt improves upon the durability and functionality of our renowned E3 bolt design. The E3.2 bolt directly addresses ejection performance, specifically when using a suppressor with a short-barreled carbine. Dual ejectors allow reduced wear and longer life compared to the legacy standard single ejector, with a longer duration of ejection force applied to the case head due to the ejector locations.

Integrated Trigger Guard
The trigger guard has been made an integral part of the SR-15 lower receiver, eliminating weak-points that can be easily damaged during trigger-guard installation and removal. Strengthening the lower receiver itself allows other features to be added without risking structural integrity over tens of thousands of rounds of use or falls from heights. The ITG retains the feel and aesthetic of the removable SR-16’s “Combat Trigger Guard”, which allows flexibility of firing hand placement and compatibility with standard grips.
