PTS Centurion Arms CM4 with KWA AEG3 System Airsoft AEG Rifle (Model: Go Airsoft Package)

The PTS Centurion Arms CM4 with KWA AEG3 System (Go Airsoft Package) represents the next evolution in electric recoil rifles. Built from the collaboration between PTS Syndicate, Centurion Arms, and KWA, this high-performance AEG delivers unmatched realism, precision, and durability for both training and field use. Whether you’re a serious airsoft competitor or a tactical enthusiast, this rifle is designed to perform flawlessly under any condition.

Authentic Construction & Combat-Ready Performance

The PTS Centurion Arms CM4 C4-10 ERG is engineered for realism and reliability. It features a 10-inch Centurion Arms C4 M-LOK rail paired with a 10.3-inch CQB-length barrel, creating a perfectly balanced setup for both close-quarters and mid-range engagements. The rifle’s full metal receiver and components ensure long-term durability, while the enhanced polymer furniture—including the EPG Compact grip, EPS stock, and EPBUIS sights—adds both comfort and function.

Internally, the CM4 is powered by KWA’s AEG3 gearbox system, featuring an Electric Recoil Gun (ERG) mechanism that replicates the recoil impulse of a gas blowback rifle. This gives players a satisfying, realistic feedback shot after shot, without sacrificing the consistency and reliability of an AEG platform.

Advanced Kinetic Feedback System (KFS)

At the heart of the AEG3 is the Kinetic Feedback System, a proprietary technology developed by KWA to simulate authentic recoil. This system provides a responsive, GBBR-style firing experience with every trigger pull, elevating realism without sacrificing battery efficiency or control.

When paired with the included Enhanced Polymer Magazine (ERG), the rifle offers an electrical auto cut-off feature that stops firing when the magazine is empty—just like a real rifle. Players can switch the mag’s capacity between 30 rounds (real-cap) and 120 rounds (mid-cap), offering flexibility for both milsim and skirmish environments.

User-Friendly Customization

The CM4 is equipped with a quick-change spring system, allowing users to easily adjust FPS without opening the gearbox—perfect for players who switch between indoor and outdoor fields. The rifle is rear-wired with a Deans connector and fully LiPo ready, capable of handling the power and performance of 11.1v LiPo batteries.

Every detail, from the Enhanced Back-Up Iron Sights (EPBUIS) with windage and elevation adjustments to the EPS stock’s integrated storage compartments, has been designed for performance and practicality in real combat environments.
