Description.

The Specna Arms SA-G01 M4A1 airsoft rifle with integrated 40mm grenade launcher is a tactical powerhouse built for players who demand both performance and realism. Constructed primarily from a high-grade zinc and aluminium alloy, and reinforced at stress points with steel components, this replica delivers an authentic look and robust durability. The adjustable stock, grip, and foregrip are made from quality polymer, striking a balance between comfort and function during prolonged skirmishes.

This upgraded version of the SA-G01 features the acclaimed Enter & Convert™ quick spring change system. Within moments, users can switch between the factory-installed M120 spring for ~410 FPS or the included M90 spring for a reduced ~310 FPS, ideal for indoor games. No need for special tools or workshop access – just practical, fast adaptation to any airsoft field rule set.

Under the hood, Specna Arms didn’t cut any corners. The reinforced V2 gearbox boasts 8mm ball bearings, a polycarbonate piston with steel teeth, and steel gears – all designed for long-term reliability and smooth cycling. A metal cylinder head and a sealed nozzle further enhance air compression, while the rotary hop-up unit ensures consistent accuracy shot after shot. This rifle is tuned for both range and precision right out of the box.

But what sets this model apart is the included 40mm grenade launcher. Fully functional and mounted directly under the barrel, it adds serious firepower and realism to your loadout. The launcher is compatible with standard gas-powered 40mm grenades (sold separately), making it perfect for clearing rooms or suppressing enemies in milsim scenarios. Combined with the rifle's realistic bolt catch and adjustable carry handle rail, the SA-G01 delivers immersive gameplay like no other.

The outer barrel features a 14mm CCW thread, allowing users to attach mock suppressors or tracer units. With its extendable buttstock and ergonomic profile, the rifle adapts well to all player builds and styles. At 410 FPS, it's primed for outdoor engagements, while a quick spring swap makes it just as effective in CQB arenas. This Specna Arms airsoft rifle is not only compatible with a wide range of magazines from brands like BOYI, King Arms, and MAG but also engineered to perform under all battlefield conditions.
