Overview of KAC KS Series
The KAC (Knight’s Armament Company) KS Series (Knight's Stoner) is a next-generation M4-platform assault rifle, an evolution of the traditional SR-16. Designed for special forces and law enforcement agencies, in 2023, the British Army officially adopted the KS-1 as the L403A1.
The most significant features of the KS Series are its fully ambidextrous lower receiver and integrated trigger guard. The ambidextrous selector, magazine release, and bolt catch allow for intuitive operation by both right- and left-handed users. Furthermore, the trigger guard is integrally molded with the lower receiver, enhancing rigidity and improving operability when wearing gloves.
The gas system employs a self-indexing, high-efficiency gas block, and a straight gas tube with a nut-fixed structure improves maintainability. In addition, it features an E3 enhanced bolt, increasing durability and operational reliability.
Equipped with a ball-mill dimpled barrel for reduced weight and improved thermal management, a URX 6 free-float handguard (M-LOK specification), a modern flash hider compatible with QD mounts, and standard Magpul grips and stocks, the design boasts high expandability. Compared to traditional M4 platforms, the KS Series, with its improved operability, durability, and maintainability, is considered the next-generation standard rifle.
Available in four variations:
KS-1 (13.7 inches): Adopted by the British Army. Mid-length gas system (this product).
KS-2 (14.5 inches): Standard carbine size.
KS-3 (11.5 inches): For CQB. Adopted by the Korean 707th Special Mission Group.
KS-4 (16 inches): Model for precision shooting.
About WELL PRO KS1/KS-3
Faithfully reproducing KAC (Knight’s Armament Company)'s state-of-the-art rifle, it appears as a toy gun. It is entirely newly produced without reusing conventional parts, featuring meticulous detail reproduction in the receiver, handguard, ambidextrous selector, ambidextrous magazine release, ambidextrous bolt catch, and ambidextrous charging handle.
The receiver is made of resin (nylon fiber reinforced polymer), ensuring high rigidity while being lightweight. Key components use metal, achieving both strength and precision. The handguard and outer barrel are aluminum CNC machined, improving weight balance and texture.
The internal gearbox is equipped with advanced features such as 6-stage precocking, binary trigger (semi-auto), and 3-round burst (full-auto). Furthermore, for durability, it uses a CNC machined steel gear set (3-tooth cut sector gear), aluminum CNC machined piston head, and cylinder head.
Additionally, it comes standard with an Infinity Brushless Motor STD 40K, achieving high response, high acceleration, and high efficiency, while also possessing excellent characteristics such as low heat generation, low power consumption, low vibration, and low noise.
*Caution: The brushless motor model is exclusively for 7.4V LiPo batteries. Using any other battery may cause malfunction, so please be careful.
