Fully Licensed KAC KS-1 Rifle
The KS-series of carbines is the next step in Knight’s continued refinement of the AR-15 platform, with improvements to ergonomics, maintenance procedures, and function. The KS-Series of carbines are available in multiple 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. The URX6 handguard system offers not only ample M-LOK negative-space mounting provisions and a comfortable grip profile, it is also notably resistant to shift from impact, while also easily replaceable.


The KAC E3.2 bolt improves upon the durability and functionality of our renowned E3 bolt design, directly addressing ejection performance, specifically when using a suppressor with a short-barreled carbine. The lower receiver has been updated with a functionally mirrored bolt catch and release on both sides of the receiver. Each SR-16 model was born from professional-user programs, resulting in purpose-built solutions to specific 5.56mm carbine requirements, as well as single solutions to cover multiple applications.
