Description

The G&G CM16 STEALTH 556 Combat Machine AEG in Black takes the familiar Combat Machine platform and gives it a thoroughly modern makeover. With its angular handguard, practical ambidextrous controls and reinforced gearbox, this airsoft rifle has plenty going for it beyond its good looks. Whether you're putting together your first proper skirmish loadout or fancy something different from the usual M4-style electric rifle, the STEALTH 556 deserves a closer look.

G&G has been making Combat Machine airsoft guns for years, and there's a reason you still see them regularly at skirmish sites. They're straightforward to use, comfortable to handle and generally offer a sensible foundation for future upgrades. The CM16 STEALTH 556 follows that same thinking but adds some genuinely useful improvements. Not just another black M4 with a different handguard, then.

10-Inch Hybrid RIS/M-LOK Handguard

Starting at the front, the STEALTH 556 features a 10-inch hybrid RIS/M-LOK handguard. This combines two popular accessory mounting systems, giving you more freedom when setting up your airsoft assault rifle. RIS rails provide a familiar mounting surface for compatible accessories, while M-LOK slots let you position suitable attachments without covering the entire handguard in bulky rail sections.

Fancy fitting a tactical torch for darker CQB environments? No problem with the appropriate mount. Prefer a compact foregrip for woodland games? There's room to build a comfortable setup. The hybrid arrangement is particularly handy if you've already collected a mixture of RIS and M-LOK accessories.

The handguard also gives the STEALTH 556 its distinctive modern appearance. It's purposeful without being unnecessarily complicated, and the lightweight polymer construction helps keep the rifle manageable during longer games. Anyone who's spent an afternoon carrying a heavy metal-bodied replica will appreciate that.

Flip-Up Sights and Practical Ambidextrous Controls

Moving back along the upper receiver, you'll find dual-profile flip-up sights. These provide a useful aiming option straight from the box, without needing to buy a separate optic immediately. They can also be folded down when not required, which is handy if you decide to fit a compatible red dot sight later.

One particularly welcome feature is the ambidextrous magazine release and bolt catch. Left-handed players often get the short end of the stick with traditional M4-style controls, so having access from either side makes the rifle more accommodating. Right-handed players benefit too, especially when switching shoulders around barricades or working through tight corners.

It's the sort of detail you might overlook while browsing photographs, but you'll appreciate it once you're actually handling the gun.

Reinforced Version 2 MIG Gearbox

Inside the CM16 STEALTH 556 sits a reinforced Version 2 MIG gearbox. This is an important part of the package because the gearbox houses the mechanical components responsible for cycling the Airsoft AEG each time you pull the trigger.

Version 2 gearboxes are widely used across M4-style electric airsoft guns, making them a familiar platform for players and airsoft technicians. G&G's reinforced MIG design provides a solid starting point for regular skirmishing while leaving scope for compatible internal upgrades further down the line.

Perhaps the most interesting mechanical feature is the quick-change spring system. Using the supplied tool, you can access the spring through the buffer tube without completely stripping down the gearbox. That's a welcome improvement over older designs where changing a spring could mean a lengthy session at the workbench.

Why does that matter? Different airsoft sites have different FPS and energy limits. Being able to change the spring more conveniently makes it easier to configure your rifle for the requirements of your chosen site. You'll still need to check the resulting power with a chronograph, of course. A spring change isn't a guaranteed FPS figure, and site limits always come first.

Adjustable GOS-V15 Stock

At the rear, G&G has fitted its adjustable GOS-V15 stock. This allows you to change the length of the rifle to suit your reach, clothing and preferred shooting position. A shorter setting can feel more comfortable when moving around buildings, while extending the stock may give you a more natural stance during outdoor games.

The stock also incorporates a battery compartment, keeping the electrical power source housed within the rifle rather than hanging awkwardly outside. It's a practical arrangement that suits the STEALTH 556's clean appearance.

30-Round Mid-Cap Magazine

G&G supplies the CM16 STEALTH 556 with a 30-round mid-cap magazine. Unlike high-capacity magazines that use a winding mechanism, mid-caps feed BBs through an internal spring. They're popular with players who prefer quieter magazines without the familiar rattle of loose BBs.

Thirty rounds also encourage a slightly more measured playing style. Rather than holding the trigger down and hoping for the best, you'll find yourself paying closer attention to ammunition and magazine changes. It's good practice, particularly if you're interested in more realistic skirmish loadouts.

Who Is the G&G CM16 STEALTH 556 For?

This black Combat Machine makes sense for newer players who want a capable electric BB Gun without immediately diving into complicated upgrades. At the same time, the reinforced gearbox, quick-change spring arrangement and accessory-friendly handguard give more experienced airsofters something useful to work with.

It's a versatile airsoft gun for woodland skirmishes, urban environments and general weekend gameplay. The familiar M4-style layout keeps things approachable, while the updated controls and internals give the STEALTH 556 a personality of its own.
