M4 CQB-R MOD0 Airsoft Assault Rifle Sports Line ETU - S&T

The M4 CQB-R MOD0 carbine replica from the Sports Line series by the renowned manufacturer S&T Armament is an ideal choice for players looking for a solid, compact, and reliable AR15/M4 airsoft replica at an affordable price. This model was designed for dynamic CQB (Close Quarters Battle) gameplay, offering excellent maneuverability, modern technical solutions, and high-quality craftsmanship. The construction is based on the AR15 platform used by Navy SEALs, widely known from games, movies, and military applications.

Solid construction – durable nylon and metal components for maximum longevity

The replica’s body is made of fiber-reinforced nylon, providing good mechanical resistance and a realistic matte finish. Unlike the glossy ABS used in cheaper replicas, nylon is more flexible and resistant to damage. Components such as the trigger, trigger guard, charging handle, QD mounts, and barrel are made of metal, significantly increasing durability and realism. The overall build quality is excellent, with a solid construction free from wobbling or unwanted movement.

Compact dimensions – ideal choice for CQB and extended games

The replica weighs 2.4 kg and measures 71 cm in length, placing it within the optimal 65–75 cm range, ideal for CQB scenarios and combat in tight spaces. The 6-position adjustable stock allows users to customize the length according to their preference. Inside the stock there is space for a battery up to 3000 mAh, providing extended operational time on the field.

Advanced V2 gearbox with ETU – 20 RPS and quick spring change system

The replica is equipped with a reinforced V2 gearbox featuring 18:1 steel gears. The integrated ETU (Electronic Trigger Unit) improves trigger response, protects the electrical system against overload, overheating, and short circuits, and extends contact lifespan. The system is compatible with 11.1V LiPo batteries, allowing a rate of fire of approximately 20 RPS, comparable to mid-range replicas. In addition, the quick spring change system without gearbox disassembly makes it easy to adjust power levels according to field FPS limits.

Full Picatinny rail and 14 mm CCW thread – ready for accessories and customization

The model features a full-length 22 mm Picatinny rail mounted on the upper receiver and handguard, allowing quick attachment of accessories such as red dot sights, grips, and flashlights. In addition, the removable flash hider reveals a 14 mm CCW thread compatible with mock suppressors or compensators.

390–400 FPS and rotary hop-up – effective at short and medium range

The replica delivers a muzzle velocity of 390–400 FPS (a lower-power version is also available), making it suitable for various field FPS limits. It performs effectively at distances up to 60 meters, excelling in both CQB and mid-range engagements. Accuracy is ensured by the rotary hop-up chamber for precise adjustment and the TM-standard bucking, which facilitates future maintenance and replacement.

Adjustable stock and 120 BB Mid-Cap magazine – ready for loadout expansion

The 6-position adjustable stock allows users to customize the replica length to their preference. The set includes a 120 BB Mid-Cap magazine, offering silent and consistent feeding. The replica is compatible with magazines from other popular manufacturers. Battery and charger are not included but are available separately.
