WE Tech M4A1 CQB Gen 3 Gas Blowback Airsoft Rifle in Black

The WE Tech M4A1 CQB Gen 3 GBBR is an absolute standout in the world of gas blowback rifles—a modern take on one of airsoft’s most iconic platforms, now supercharged with WE’s refined open-bolt blowback system. This full-metal airsoft gun isn’t just built to look good—it’s designed to shoot hard, feel real, and handle like the real deal. If you want an M4 GBB that’s battle-tested, skirmish-ready, and dripping in realism, this is it.

Constructed primarily from anodised aluminium, the M4A1 CQB Gen 3 is built with realism in mind. The full-metal receiver, barrel assembly, and functional bolt carrier offer weight and durability that make it a worthy training tool and a serious skirmish weapon. The only polymer parts here are the stock, pistol grip, and handguard—just like the real steel. With a weight of 3060g, it shoulders well and has the mass to soak up recoil while keeping things nimble in CQB environments.

It fires at a fierce 430 FPS with 0.2g BBs (around 1.72J), making it a solid choice for outdoor play, with a muzzle velocity that can deliver effective range and solid impact. The gas blowback system is what makes it shine though. Each shot comes with sharp recoil, loud mechanical clatter, and that glorious bolt-action movement. Plus, it’s got realistic features like bolt lock on empty and a fully functional charging handle. Pull it back and you’ll see the open bolt system in action—it’s as close to real steel as airsoft gets.

Fire modes include semi and full-auto, and the cyclic rate is quick—up to 19 rounds per second when fully gassed and warm. That’s more than enough to keep heads down in a tight corner or deliver a satisfying burst across the field. Just be cautious with the full-auto in cold weather—like all gas rifles, performance drops when the temperature dips. Green Gas is the go-to, but keep your mags warm for best performance.

The M4A1 Gen 3 features an adjustable hop-up that allows you to tune the BB trajectory for your preferred ammo weight. The internal barrel is 6.04mm tight bore, helping deliver consistency and tighter groupings when you dial it in. Out front, you get a 14mm clockwise aluminium flash hider, and removing the detachable carry handle reveals a 20mm weaver rail—perfect for mounting optics or accessories.

Other touches that round out the package include a two-piece aluminium outer barrel, extendable telescopic stock for length adjustment, and plenty of steel-reinforced parts—pivot pin, bolt catch, rear sight, flash hider, and more. The overall fit and finish make this feel like a high-end tool, not a toy. Plus, with WE’s solid internal system, spare parts and upgrades are easily available for the modders among us.

Whether you're stepping into gas blowback for the first time or upgrading from an AEG, the WE Tech M4A1 CQB Gen 3 offers a blend of authentic handling, serious performance, and battlefield presence. It’s loud, punchy, and built to be used—not babied. Just keep it gassed, keep it warm, and it’ll do the rest.
