The
United States military, as well as other special forces and police around the world, use KAC
RIS/RAS conversions for many popular firearms, including the American
M16/
M4 rifles and
Heckler & Koch MP5 series
submachine guns. The RIS/RAS system allows for the mounting of accessories to firearms without additional tools or modifications. The system is utilized alongside a KAC suppressor and forward grip on the "Special Operations Peculiar MODification" (
SOPMOD) M4 carbine package in use by
United States Special Operations Command (USSOCOM). The mounted accessories can include tactical flashlights, laser targeting units,
bipods, and
vertical foregrips. KAC produces
sound suppressors for the
Heckler & Koch Mark 23 SOCOM pistol. KAC also produces a line of clip-on night vision and thermal weapon sights, including the
AN/PVS-22 Universal Night Sight. KAC produces mounts for optics and grenade launchers, as well as backup iron sights. Knight's Armament produces a line of firearms including the semi-automatic SR-15 line of rifles, the fully automatic SR-16 carbine, the semi-automatic SR-25 sniper rifle, the SR-25 based
Mark 11 Mod 0 Sniper Weapon System, and the
M110 Semi-Automatic Sniper System. KAC designed and produces the
Knight's Armament Company PDW and also produces the
Stoner LMG in limited quantities. In 2011, KAC released the SR15/SR16 E3 line of rifles. In September 2023, the company was selected to provide the
Knight's Stoner 1 variant of its SR-16 rifle to the
British Army Special Operations Brigade and to the
Royal Marines. ==References==
