ASG - FLCN 5.56 M4 Replica AEG Airsoft Rifle - Black

Meet the ASG FLCN 5.56 M4 Replica AEG—an electric airsoft rifle that brings together tactical versatility, futuristic aesthetics, and solid field performance in one sleek platform. Part of ASG's Sportline range, this rifle is tailored for airsoft players who value comfort, modularity, and practical firepower—whether you're pushing through tight corridors or holding angles on an outdoor field. Lightweight, packed with tech, and user-friendly, the FLCN 5.56 feels like something straight out of a sci-fi movie... but it’s 100% built for real-world skirmishes.

Let’s start with the build. The entire body is made from high-strength polymer, keeping the weight down to just 2.4 kg (5.29 lbs). That’s light enough to carry all day without feeling like you’ve done arm day twice. But don’t mistake lightweight for flimsy—this thing can take the hits and keep going. The monolithic upper receiver is rock-solid, and with M-LOK slots lining the handguard, you’ve got real estate for all your favourite add-ons: angled grips, torches, lasers, whatever helps you clear a room faster or stabilize your aim.

That stock? It’s a feature in itself. The 6-position collapsible/folding design gives you a custom fit whether you’re rocking a plate carrier or running lean. The adjustable cheekrest is a godsend for scope alignment, especially during longer ops when comfort starts to matter. And when it’s time to pack up or move fast in close quarters, just fold the stock and you’ve instantly made your setup more compact.

The controls are ambidextrous across the board—selector, charging handle, bolt catch. If you're left-handed, you won’t feel like an afterthought here. Accessing the rotary-style hop-up is a breeze thanks to the locking ejection port cover. And the hop-up itself? Solid and responsive. You can dial in your shots with confidence, whether you're suppressing from afar or picking your way through a tight killhouse.

Now for the internals—this is where the FLCN really punches above its weight. Inside sits a reinforced Version 2 gearbox running on 8mm bearings for smooth operation. It’s pre-installed with an M95 spring for a snappy 328 FPS (100 m/s), but ASG thoughtfully includes an M120 spring too if you need more juice. Swapping springs is a doddle thanks to the quick-change system—no need to tear the whole rifle apart. Just drop in the new spring, and you’re ready to adapt to whatever field rules you're playing under.

Electronic trigger unit? Check. Built-in MOSFET? Yep. Together, they give you clean trigger response and gearbox protection while helping to extend your battery life. Speaking of batteries, this airsoft AEG comes pre-wired to a Deans/T-Plug for better electrical flow, and ASG even throws in a mini Tamiya adapter if you're still using older batteries. It’s those little quality-of-life inclusions that make this rifle feel thoughtfully put together.

Magazine compatibility is worry-free—standard AR-style AEG mags slot in without a hitch. And the included 180-round mid-cap gets you plenty of trigger time before needing a reload. There are also QD sling mount points front and back, so you're sorted whether you’re running a single-point or two-point sling setup.

Bottom line: the ASG FLCN 5.56 M4 Replica is a fantastic all-rounder that doesn’t just look modern—it plays modern. Agile, modular, and responsive, it's a great choice for any player looking to future-proof their loadout without breaking the bank or diving into a sea of aftermarket upgrades.
