Double Bell M16A4 with Grenade Launcher (Full Metal - Black)

The Quintessential Infantry Rifle

Instantly recognizable and highly respected, the M16A4 is the ultimate platform for players who prefer traditional woodland engagements over tight indoor CQB. This AEG captures the authentic infantry feel flawlessly. Constructed with a heavy-duty metal receiver and outer barrel, it weighs in at a highly realistic 3385g. To ensure comfortable handling during long patrols, it features a durable, high-impact polymer pistol grip and a classic fixed stock. This solid construction provides an incredibly rigid shooting platform that completely eliminates barrel flex, ensuring your sights stay perfectly aligned with your target.

Outrange the Competition

Where this rifle truly shines is in its internal barrel assembly. Because it utilizes the full-length M16 profile, it houses an exceptionally long 500mm inner barrel. Furthermore, this isn't just a standard tube; it is a 6.02mm (±0.01) precision tightbore barrel. When paired with the easily adjustable rotary hop-up unit, this AEG delivers laser-like accuracy and an incredibly tight shot grouping. Firing at a consistent 330 FPS, it allows you to reach out and comfortably pick off enemy players who are using shorter, less accurate platforms.

Reliable V2 Performance & Massive Battery Space

At the heart of this M16 is a tried-and-tested Metal Version 2 Gearbox. Renowned across the airsoft industry for its reliability and massive aftermarket upgrade potential, it provides crisp semi-automatic fire and a blistering full-auto rate of fire. The system is rear-wired to a standard Mini Tamiya connector hidden within the fixed polymer stock. A massive advantage of this classic stock design is the sheer amount of battery space it offers. You can easily fit large, high-capacity block LiPo batteries, completely eliminating the need to carry spares or recharge halfway through a game day.

Skirmish-Ready Firepower

To ensure you are ready for sustained firefights, the rifle comes supplied with a 300-round high-capacity magazine, giving you plenty of ammunition to lay down thick suppressive fire. Additionally, the tip of the outer barrel features a standard 14mm Counter-Clockwise (CCW) thread, allowing you to seamlessly attach your favourite aftermarket suppressors or tracer units for low-light games.
