ASG - FLCN 5.56 M4 Replica Airsoft AEG Rifle - Black

The ASG FLCN 5.56 M4 Replica is a futuristic reimagining of the classic platform, tailored for players who demand adaptability, tech-driven internals, and lightweight handling all in one sleek airsoft rifle. Part of ASG’s Sportline series, this electric rifle is built for aggressive maneuvering and extended gameplay, delivering standout performance whether you’re clearing rooms or locking down lanes outdoors.

Weighing in at just 2.4 kg (5.29 lbs), this rifle’s lightweight full polymer body doesn't skimp on durability. The build quality feels solid in the hands, and the design turns heads without being over-designed. A monolithic upper receiver flows seamlessly into the M-LOK handguard, giving you ample room for tactical upgrades—lasers, torches, grips, you name it. Whether you prefer running light or decked out with attachments, the M-LOK slots at the 3, 6, and 9 o’clock positions are ready to customise.

Versatility is clearly baked into the DNA of this airsoft gun. The 6-position collapsible and folding stock includes a 4-position adjustable cheekrest, letting you dial in the perfect fit regardless of your stance or gear setup. Quick-detach sling mount points are built into both the handguard and stock, so your carry options remain as flexible as your playing style.

Controls on the FLCN 5.56 are fully ambidextrous, from the charging handle to the fire selector and bolt catch. Whether you’re left-handed, right-handed, or just like to switch shoulders mid-match, this rifle won’t get in your way. The rotary hop-up is conveniently accessed through a locking ejection port window, allowing fast mid-game tweaks to your shot consistency and range.

Under the hood, the FLCN 5.56 runs on a reinforced Version 2 gearbox with 8mm bearings and a quick-change spring system. It comes fitted with an M95 spring, producing a site-friendly 328 FPS (100 m/s) with 0.20g BBs—perfect for most UK sites. For those outdoor days when you need a bit more punch, the included M120 spring gives you the power bump you’re after. Thanks to the programmable ETU and built-in MOSFET, trigger response is snappy and crisp, and you’re getting smart battery protection and consistent electrical flow every time you pull the trigger.

Speaking of batteries, the compartment in the stock is wired with a Deans/T-Plug connector for maximum efficiency and current flow. But if you're still running mini Tamiyas, don’t worry—an adapter is included, so you’re covered either way. Magazine compatibility is equally flexible; the FLCN 5.56 works with most AR-style AEG mags, removing any guesswork from your loadout planning.

Whether you’re stepping up from a basic starter rifle or looking to add a uniquely styled and function-packed M4 variant to your collection, the ASG FLCN 5.56 delivers tactical edge with futuristic flair. It looks sharp, feels great, and performs consistently right out of the box—ready to adapt to whatever the skirmish throws at you.
