Overview of the KAC KS Series
The KAC (Knight’s Armament Company) KS series (Knight's Stoner) is a next-generation M4-style assault rifle that evolved from the conventional SR-16. Designed for special forces and law enforcement agencies, the British Army officially adopted the KS-1 as the L403A1 in 2023.
The most distinguishing features of the KS series are its fully ambidextrous lower receiver and integrated trigger guard. The ambidextrous selector, magazine release, and bolt catch enable intuitive operation for both right- and left-handed users. In addition, the trigger guard is integrally molded with the lower receiver, improving rigidity and ease of operation when wearing gloves.
The gas system features a self-indexing, high-efficiency gas block, and a straight gas tube with a nut-fixed structure for improved maintainability. Furthermore, it is equipped with an E3 Enhanced Bolt, which enhances durability and operational reliability.
It is designed for high expandability, featuring a ball-milled dimpled barrel for reduced weight and efficient heat management, a URX 6 free-float handguard (M-LOK specification), a latest flash hider compatible with QD mounts, and Magpul grips and stocks as standard equipment. Compared to the conventional M4 platform, the KS series boasts improved operability, durability, and maintainability, positioning it as the next-generation standard rifle.
Available in 4 variations:
KS-1 (13.7 inches): Adopted by the British Army. Mid-length gas system.
KS-2 (14.5 inches): Standard carbine size.
KS-3 (11.5 inches): For CQB. Adopted by the South Korean 707th Special Mission Group.
KS-4 (16 inches): Model for precision shooting.
About the WELL PRO KS1/KS-3
KAC (Knight's Armament Company)'s state-of-the-art rifle is faithfully reproduced and now available as an airsoft gun. It has been completely redesigned from scratch without reusing conventional parts, featuring meticulous reproduction of details such as the receiver, handguard, ambidextrous selector, ambidextrous magazine release, ambidextrous bolt catch, and ambidextrous charging handle.
The receiver and handguard are made of reinforced resin (nylon fiber reinforced polymer), ensuring high rigidity while being lightweight. Metal is used for key components to achieve both strength and precision. The outer barrel and stock tube are made of aluminum CNC machining, improving weight balance and texture.
The internal gearbox is equipped with advanced functions such as 6-stage precocking, binary trigger (semi-auto), and 3-round burst (full-auto). Furthermore, for durability, it features a steel gear set (sector gear with 3 teeth cut) and CNC-machined steel bearings.
