Knight's Armament KS-3 9,5" GBB Replica - TAN [EMG]

The WELL PRO KS-3 gas blowback airsoft rifle, produced under license from Knight's Armament, is based on the AR15 platform and draws on the compact configuration of the SR-16 rifle. The model combines metal construction, a gas blowback system with a metal bolt carrier assembly, and two GBB magazines included. The M-LOK URX handguard, adjustable SF-style stock, and ambidextrous controls support efficient handling during CQB, milsim events, and dynamic outdoor games.

WELL PRO KS-3 gas blowback airsoft rifle - compact GBBR design

The KS-3 is a GBBR airsoft rifle produced under license from Knight's Armament. Its design draws on the compact SR-16 configuration, combining a short form with controls adapted for operation with either the right or left hand.

The airsoft gun is made of metal, with CNC machining used in the manufacturing process. The gas blowback system cycles the bolt carrier assembly with every shot, supporting realistic operation and producing clearly noticeable recoil.

Construction and M-LOK system

The airsoft gun is equipped with a 9.5-inch URX handguard. Multi-directional M-LOK slots allow additional accessories such as a flashlight or foregrip to be mounted, making it possible to adapt the equipment configuration to the intended use.

A full-length RIS mounting rail runs along the upper receiver and handguard, allowing a red dot or riflescope to be fitted.

Gas system and hop-up

The airsoft gun uses a gas blowback system in which the bolt carrier assembly cycles with every shot. The metal construction increases the weight of the moving assembly, allowing the gas system to produce a noticeable response each time the trigger is pulled.

The NPAS system allows the power output to be adjusted according to the temperature, BB weight, and limits applicable during a game. Access to the hop-up adjustment is located on top of the upper receiver, within the mounting rail, making it easier to correct the BB trajectory.

Internal parts and mechanics

WELL PRO uses its own reinforced steel internal components, including fire-control parts and a metal bolt carrier assembly. This construction supports the durability of the mechanism during intensive use.

The trigger has a short travel, quick reset, and clearly defined break, supporting rapid follow-up shots. The inner barrel has been selected for the compact configuration of the airsoft gun and supports shot consistency and accuracy during CQB games.

The manufacturer also uses its own magazine design inspired by VFC MWS AR15/M4 solutions. Its construction was developed to support efficient gas delivery and correct operation of the GBB system.

Ergonomics and handling

The airsoft gun features an ambidextrous charging handle, magazine release, fire selector, and bolt catch. The control layout makes the mechanism easier to operate for both right- and left-handed users without changing the primary grip.

The adjustable 6 - position SF-style stock allows the length of pull to be adapted to the user's preferences and current equipment configuration. Fully collapsing the stock makes storage, transport, and handling in confined spaces easier.
