After something with a bit more presence than an M4A1? This M16A4 replica will do the trick!

With a full-metal build and ready to be dressed up with 20mm Picatinny accessories wherever you need them, the CM.009A4 makes a superb outdoor primary thanks to its 6.03mm tightbore inner barrel, which measures a whopping 509mm in overall length, enhancing accuracy and boosting FPS.

Full description

Description

Whether you're working on a USMC loadout or you're after a large and in charge M4 variant, the CYMA CM.009A4 M16A4 M5 RAS AEG Assault Rifle should be in your sights! A full metal build with a 20mm Picatinny railed receiver, detachable carry handle with ghost ring rear sight and M5 RAS 20mm Quad-railed handguard, this M16 is kitted out, ready to be equipped with whichever accessories you need to complete the mission at hand. Those already familiar with the M4 platform, this M16A4 makes the perfect long-range alternative!

Starting at the tip of the lengthy 20" outer barrel, we can find an alloy A2 birdcage flash hider, the iconic M16 flash hider design, complete with the enclosed lower section of the A2 version. The enclosed section is designed to prevent dirt and debris from obstructing the shooter's sightline and also helps control recoil and conceal muzzle flash.

If you're building a custom M16 or a DMR-style platform, you'll be happy to learn that the birdcage can be swapped for any 14mm CCW male threaded muzzle device, including suppressors, tracer units or alternative flash hiders and muzzle brakes. Just remember to remove the grub screw in the flash hider before attempting to unscrew it!

Moving rearward, we can take note of the correct heavy profile outer barrel of this M16A4 replica, designed in the real world to help the M16 cope with rapid fire without losing accuracy. Being 20 inches in length, this outer barrel contains a whopping 509mm inner barrel with a 6.03mm bore, giving the CM.009A4 superb accuracy potential and squeezing a bit of extra FPS out of the same power spring thanks to air efficiency improvements.

The front iron sight is the standard M16 fixed front post, which doubles as the gas block in the real deal. The sight is constructed from alloy, and the sight blade is adjustable for elevation using an AR-15 front sight adjustment tool. On the bottom of the front sight, we also have a sling point and bayonet lug, which is compatible with most Airsoft M9 bayonet replicas.

The M5 RAS-style handguard follows behind the front sight, made from CNC-machined aluminium to guarantee flawless rail spec. The M5 RAS features 20mm Picatinny rails on all sides, allowing 20mm Picatinny accessories to be mounted wherever you need them, from vertical and angled foregrips to tactical flashlights, aiming lasers and more! If you're going for the USMC M16A4 look, we recommend a PEQ-15 Laser/Light Module and a KAC-style Vertical Foregrip.

A nifty trick built into the M16A4 and its M5 RAS handguard is the ability to mount an M203 40mm MOSCART Grenade Launcher directly to the barrel by removing the lower handguard, ideal for those who want to go full Arnie with their build. To remove the lower handguard, simply pull back on the Delta Ring between the handguards and receiver and you should be able to pull it off.

The receiver should be a familiar sight to anyone who has handled an M4/AR-15 platform before, constructed from alloy and matching the real M16A4/M4A1 receiver style perfectly. This includes the reinforced front pinhole, milspec flat trigger guard, magazine release fence and low profile charging handle latch. The magazine release is on the right side of the magazine well, a push-through design just like a standard M4/AR-15 AEG with a textured surface for optimal traction.

The fire selector switch is just above the pistol grip on the right side, offering 3 modes of fire with a 90-degree throw between each. The default fire modes are safe, semi-auto and full auto but with the pre-installed Kestrel Basic ETU, you have the option of using binary trigger instead of semi and 3-round burst instead of full auto. The real M16A4 used a SAFE-SEMI-3RND burst trigger group so if you want to run your CM.009A4 like the real deal you have that option built in!

The charging handle can be found at the top rear of the receiver and as mentioned, features the milspec low-profile charging handle latch to reduce snagging potential. Pulling the charging handle back will pop the dust cover open and retract the chrome-finished mock bolt, revealing the rotary HOP-up unit on the right side.

The HOP-up allows you to adjust the amount of backspin applied to your projectiles and tune the CM.009A4 for different ammo weights, looking for the flattest possible trajectory. When you've completed your adjustments, you can slap the "ping pong paddle" style bolt release catch on the left side of the receiver to drop the mock bolt with a satisfying metal-on-metal "clank".

Up top, we have a 20mm Picatinny receiver rail with a pre-installed alloy carry handle, which also contains the rear "ghost ring" iron sight. The rear sight is adjustable for both windage and elevation without requiring a single tool to do it. The dial on the right side adjusts windage (left to right), and the dial below the aperture controls elevation. If you prefer to run an optical sight, you can loosen the thumb screws on the left side of the carry handle and remove it to access your receiver rail. As much as the carry handle is an iconic part of the M16 build, an ACOG-style optic is ideal if you're going for an "in the field" look.

The pistol grip provided on the CM.009A4 is an "A2" finger-ridged type, with diamond checkering on either side and linear grooves on the rear to provide a comfortable grip. The A2 grip is exactly what an M16A4 replica needs, matching the real steel US Army and USMC-issued variant perfectly.

Bringing up the rear, we have the M16A2 fixed stock, a full-length stock featured on both the A2 and the A4 models. This stock is rather long and more suitable for loadouts without body armour, but is very comfortable when shouldered and solid as a rock. The butt plate features aggressive diamond texture for superb gripping qualities in all weather conditions and also includes a sling point at the toe of the stock. The fixed stock also serves as the battery compartment of the CM.009A4, which is great news as the space inside is absolutely cavernous!

To access the battery compartment, simply press the retaining catch on the top of the battery port door, dead centre of the butt plate. This will allow the door to open, revealing a Deans/T-plug battery connector inside. We recommend a 7.4V 2800mAh LiPo battery for an easy fit and great performance.
