Full description


This Airsoft Electric Gun is a replica of the M4/AR Platform Assault Rifles, and is powered by a Battery (not included) in the stock. Whether you're new to the hobby, or you're looking for a cost effective backup to have in your collection, then the A&K M4 CQB-R Assault Rifle will happily fill any gap you may have.

Most of the externals on this gun are made using Alloy for a realistic feel and strong core. The Polymer components of the rifle are the Pistol Grip, Stock and included Foregrip (as would be plastic on the real firearm). The front of the rifle features a 14mm CCW Threaded Barrel, hidden underneath the Flash Hider. To access the thread simply unscrew the grub screw from the Flash Hider and turn it Clockwise to remove. This allows you to install Suppressors, Tracer Units and more to your replica, whether it be to enhance the look or to get more functionality out of it. A 20mm Railed Handguard allows you to install a massive range of accessories, but it comes supplied with a comfortable Foregrip and Rail Cover set to make the traditional M4A4 layout, if that's your thing. The Carry Handle on top of the Receiver can be removed to reveal more 20mm Rail underneath, which is ideal for installing your own Sights/Scopes or an aftermarket set of ironsights. Heck, you could even install a Grenade Launcher up there. Why not? Go wild! It's your replica... The rear of the gun features a six position Sliding Crane Stock which is also where the Battery should be housed. You can either remove the Butt Pad (recommended) by squeezing the tabs at the rear of the Stock and pulling the Pad away. You can also pull down on the Stock Adjustment Lever and pull the entire Stock off the Buffer Tube - allowing you to completely replace it should you wish. The Stock has a loop at the rear which can be used in conjunction with the Front Sling Loop to make it easier to carry by adding a Sling - you will need to install some kind of loop on the Stock for most slings however.

The gun comes included with a 300rnd High Cap Magazine which is ideal for starters, as it carries plenty of ammunition and avoids frequent reloads. To fill the magazine, you need to slide open the Fill Window at the top and pour BBs into the opening. Then wind the wheel on the bottom of the mag until you can hear/feel a change in the winding as BBs reach the top of the mag. The more winds, the more the magazine will feed. It is better to wind the magazine once it is the gun, as installing it after lots and lots of winds may make the magazine unwind if you 'slap' it into the gun too hard.

As with all most modern Airsoft Guns, the A&K M4 CQB-R Assault Rifle features an Adjustable HOP Unit, which adds backspin to your BBs as the leave the barrel. This can increase your range and consistency when paired with a heavyweight BB (0.25g+) and the correct settings - we recommend adjusting this setting at the location you plan to shoot, so that you can fully account for the conditions (such as wind). To access the HOP, pull back on the Charging Handle to reveal the Gear Adjustment Wheel inside the breech, behind the mock bolt.

Whether you're a beginner looking to make their entrance into the world of Airsoft, or you're a seasoned veteran looking for a reasonably priced and solid M4 replica with a tough body, then the A&K M4 CQB-R Assault Rifle is the ideal choice.

Special Instructions

The externals of the replica are metal where they would be on the real world gun. This includes things like the outer barrel, handguard, and receiver. If a real world gun has polymer parts then the gun will still be marked as full metal externals, examples of this would be an M4, where the Stock and Pistol grip are always made from Polymer.
