The replica of the M4 Carbine 11.5" from the Sports Line series by the renowned brand S&T Armament is an excellent choice for players looking for a lightweight, reliable, and well-crafted airsoft rifle at an affordable price. The model was designed with dynamic close-quarter battles (CQB) in mind, offering maneuverability, practical features, and solid construction. The design is based on the classic AR15/M4 platform, well-known from games, movies, and used by elite units such as GROM and Delta Force.

Durable nylon body and precise fit

The body is made of durable nylon, providing mechanical resistance and a matte finish, far superior to fragile ABS. Key components - trigger, selector, charging handle, catches, and barrel - are metal, which increases realism and durability. The replica is equipped with a practical rail mounted on the receiver, allowing for the installation of accessories such as red dot sights. The overall fit and finish are excellent - the construction is stable, with no wobbling.

Compact dimensions and low weight

The M4 Carbine measures 73 cm and weighs 2.2 kg, making it perfect for tight indoor spaces and dynamic gameplay. Thanks to its low weight, it remains comfortable even during extended use. The M-LOCK mounting system allows the addition of accessories such as grips or flashlights, customizing the replica to the player's needs.

Gearbox with ETU unit

At the heart of the replica is a reinforced gearbox with 18:1 steel gears and an ETU (Electronic Trigger Unit). This solution improves trigger response, protects the electrical system, and extends the lifespan of the contacts. A strong advantage is the quick-change spring system without disassembling the gearbox, making power adjustment easy. The replica is compatible with 11.1V LiPo batteries, ensuring high rate of fire. The availability of spare and replacement parts makes maintenance and tuning simple.

Performance: ~400 FPS and 20 RPS

The replica delivers a muzzle velocity of 390-400 FPS (with an option for a weaker version at purchase) and around 20 RPS when powered by an 11.1V battery. This performance is comparable to mid-range models and clearly surpasses budget replicas, which usually reach 11-13 RPS. The effective range is up to 60 meters, making it effective at both short and medium distances. Accuracy is ensured by a rotary hop-up chamber, allowing quick and precise adjustments. Inside, it features a TM-standard bucking, making servicing and replacement easier.

Adjustable stock and mid-cap magazine

The 6-position adjustable stock allows the replica's length to be adapted to the user and houses a larger battery up to 3000 mAh, extending gameplay time. The set includes a 120-round mid-cap magazine, feeding BBs quietly and without wobble. The replica is also compatible with magazines from other popular manufacturers (A&K, CYMA, Arcturus). The battery and charger are not included but available in the store.

Proven quality from S&T

For over 20 years, S&T has been delivering respected airsoft replicas. Available at Taiwangun since 2021, the Sports Line, particularly the AK series introduced in 2024, has earned a 4.5/5 star rating and sold thousands of units.

Perfect choice under 500 PLN

In summary - the M4 Carbine 11.5" is an ideal replica for players seeking a lightweight and solid rifle at an affordable price, offering very good performance straight out of the box. Reliability, ergonomics, ETU electronics, and a classic appearance make it one of the best options in the sub-500 PLN segment.
