M4 SOPMOD Block 3 11.5" Airsoft Assault Rifle Sports Line ETU [S&T]

Replica of the M4 SOPMOD Block 3 11.5 from the Sports Line series by the renowned manufacturer S&T Armament is a solid, compact, and reliable M4 replica at an affordable price. Designed for dynamic CQB gameplay, it offers excellent maneuverability in tight spaces and also performs well in open-field scenarios. The design is based on the classic AR15/M4 configuration, known from films, games, and used by elite military units such as DEVGRU and the Green Berets.

Reinforced nylon body with M-LOCK mounting system

The replica's body is made of durable nylon, more resistant to damage than brittle ABS, while providing a realistic matte finish. For increased durability, components such as the trigger, trigger guard, charging handle, QD mounts, and outer barrel are made of metal, significantly improving the construction's robustness. The replica also features a full 22mm Picatinny rail and a modern M-LOCK mounting system, allowing convenient installation of accessories such as front grip, flashlight, or red dot sight. Everything is very well fitted.

Compact dimensions and CQB-oriented ergonomics

The M4 Block 3 has a length of 73.5 cm, within the optimal 65-75 cm range—perfect for tight indoor gameplay. The replica weighs 2.3 kg, providing good stability while maintaining high maneuverability. The SF-style stock features 6-position adjustment and space for a LiPo battery, allowing customization to the player's physique and increasing comfort during use.

Efficient ETU unit and reinforced gearbox — reliability and speed

Inside, there is a reinforced V2 gearbox with 18:1 steel gears and a modern ETU (Electronic Trigger Unit) system, improving trigger response and protecting the electrical system. Compatible with 11.1V LiPo batteries, it allows achieving around 20 RPS. Quick spring replacement enables easy power adjustment, and available service parts make maintenance and tuning straightforward.

Consistent performance and good accuracy

The replica reaches a muzzle velocity of 390-400 FPS (with optional lower power at purchase) and generates about 20 RPS on an 11.1V battery, comparable to mid-range replicas and clearly surpassing budget models (11-13 RPS). Effective range reaches up to 60 meters, making it highly effective at short and medium distances. Accuracy is ensured by a rotary hop-up chamber, allowing precise and quick adjustment. Inside, a TM-standard bucking makes servicing and replacement easy.

Battery-compatible stock and mid-cap magazine

The SF-style stock accommodates a battery up to 3000 mAh, extending operating time. Included is a 150-round mid-cap magazine that feeds BBs reliably without rattling. The replica is compatible with magazines from other manufacturers (e.g., CYMA, A&K, Double Eagle), facilitating equipment upgrades. Battery and charger are not included.
