Tokyo Marui M4A1 MWS GBB Airsoft Rifle

Tokyo Marui M4A1 MWS GBB Airsoft Rifle

The Tokyo Marui M4A1 MWS GBB Airsoft Rifle is widely regarded as the pinnacle of gas blowback airsoft rifles—and with good reason. Built to replicate the iconic US military carbine in exquisite detail, the M4A1 MWS combines superior engineering, rock-solid reliability, and Tokyo Marui's next-level gas efficiency into a hard-hitting package with full realism. From its Cerakote-finished metal receiver to the new Z-System internals, this rifle is battle-proven in the hands of elite airsoft players worldwide.

Featuring a 1:1 scale build with a 180mm front rail system and a 355mm metal outer barrel, the M4A1 MWS is ready for serious modular setups. It includes a standard fixed front sight and flip-up rear sight, making it optics-ready out of the box. The polymer grip and six-position adjustable stock are rock solid, and give this airsoft rifle the ergonomics and handling expected from a real steel setup.

Internally, the Marui M4A1 shines with its 19mm large-bore gas system, delivering sharp, authoritative recoil with every shot. This GBB system replicates the mechanical feel of a real M4, right down to the functional bolt and bolt catch. It’s not just about feel either—accuracy is enhanced through Marui’s variable hop-up system, delivering consistent shot placement whether you’re in close quarters or engaging at range.

The rifle comes with a 35-round die-cast aluminum magazine that mimics the weight and size of a real STANAG mag. Firing at stable velocities on 134a gas, the M4A1 MWS is skirmish-legal and incredibly efficient in all seasons, especially when paired with Nuprol 1.0 or similar low-pressure gas. Just remember—this is a serious gas airsoft rifle. Treat it like the real thing, and it’ll deliver every time.

Marui’s proprietary Z-System improves bolt catch durability, while the friction-relief bolt roller and piston absorber help reduce wear from intense use. The result? A longer-lasting platform that doesn’t shy away from high-round-count days. Add to that the Cerakote coating for extra scratch resistance, and you’re looking at one of the most premium GBB rifles money can buy.

The 14mm CCW threaded flash hider allows for suppressor or tracer unit attachment, expanding your customisation options. With a fully field-strippable design, you can clean and service the M4A1 MWS exactly like its real counterpart. This rifle is not just a replica—it’s a training tool, a collector’s piece, and a skirmish-ready performer rolled into one.

Whether you’re building a MilSim loadout, running CQB drills, or just want the closest experience to real firearm operation, the Tokyo Marui M4A1 MWS GBB Airsoft Rifle delivers authenticity, consistency, and raw mechanical satisfaction in every trigger pull.
