Code:
254.99
  • Authentic "Plum" furniture
  • Steel receiver, top cover and stock
  • High-speed version - 13:1 Gearset pre-installed


For those with a thing for the classic utilitarian style of the AK platform who need a rifle for CQB duties, the AKS-74U has your name on it! The CM.045 High-Speed from CYMA takes the original CM.045's superb externals and drops in a 13:1 steel gearset, high-speed motor, silent piston and cylinder head with a polycarbonate piston with steel teeth to provide a pre-upgraded speed demon of an AK! To sweeten the deal, this AKS-74U comes with authentic-looking "Plum" coloured polymer furniture and magazine, matching AKs built during the 1985-1989 era.

Full description

Description

The CM.045 High-Speed continues CYMA's tradition of providing upgraded high-speed variants of their AEG line-up, and like the other high-speed CYMA AEGs, this one has a very impressive trigger response and a mean rate of fire with a gearbox that sounds ultra-smooth and unlaboured. On the outside, the CM.045 High-Speed is equally impressive, retaining the robust build quality of the original CM.045 with its high proportion of steel components for added realism and a substantial feel in the hands.

Starting at the tip of the alloy outer barrel we can find the muzzle device, which attaches to the 24mm CW AK threads on the front sight/gas block. The muzzle device is the correct design for an AKS-74U of this era, complete with ribs on the exterior marking it out from earlier AKS-74U models. The front sight is adjustable for elevation using the included front sight tool and is housed inside the gas block/front sight block combination, a hallmark of the AKS-74U. 

Beneath the 24mm CW AK threads are 14mm CCW threads, which can be accessed by removing the grub screw under the muzzle device, and unthreading the 24mm CW adapter. This adapter is held on with some form of adhesive, so please be careful not to strip any threads when removing the grub screw and adapter. The front sight/gas block also includes a sling point on the left side, which can be used in concert with the sling point on the stock to attach a two-point rifle sling.

Moving rearwards we come to the plum coloured ribbed handguards, matching the more modern variant of the AKS-74U first issued in the mid-1980s. The ribs provide ample grip for operating in any weather condition and have a comfortable profile that fills out the hand. Whilst some may prefer the look of wood grips, they definitely cannot compete with the more modern ribbed handguards of this AKS-74U when it comes to controlling the weapon. 

The plum coloured furniture is one of the standout features of this particular AKS-74U and is widely regarded as the nicest looking authentic polymer furniture available for the AK platform. The plum colouration of these handguards is also a nice nod to realism as it matches well with the authentic plum furniture issued to soviet troops between 1985 and 1989. The handguards are held onto the rifle using handguard caps, the lower of which is made from alloy with the upper handguard caps being constructed from steel.

As we reach the receiver we can see the authentic AKS-74U trunnion block, to which the steel hinged top cover mounts. None of that "AK Beta Spetsnaz" rubbish here, only proper realistic AK design aesthetics! The hinged top cover is an excellent improvement over the original removable AK top cover, first seen in the AKS-74U. This convenient feature has since found its way onto the recently developed AK-12 and many civilian tactical AKs, such as those made by Rifle Dynamics in the US. 

The top cover is a ribbed design to match the AK74 top cover variant, and its hinge also contains the rear iron sight of the AKS-74U. This rear iron sight is of the "open" style, staying faithful to the real AKS-74U and providing the choice of two apertures for aiming. The aperture marked "4-5" is intended for engaging at 400-500m, which is optimistic for the real AKS-74U, let alone an Airsoft AEG! We recommend dividing range markings by ten, and to treat this as being for 40-50m shots. The aperture marked with an inverted U symbol is the "combat" sight, intended for close to mid-range engagements.

The battery compartment of the CM.045 High-Speed is located beneath the top cover and can be accessed by pushing the button at the rear of the top cover down, after which the cover will hinge open. Within you will find a mini-Tamiya connector to which you connect your battery. With your battery installed inside, the top cover can be pushed back down, where the spring-loaded button will lock it back into place. For the CM.045, we recommend an 11.1V 1200mAh LiPo battery for a good fit beneath the top cover.

Moving down to the receiver itself, we can see authentic rivets and mock rivets, authentically positioned to match the layout of the real firearm. This is always nice to see and adds a touch of extra realism for those who want the most faithful replica out there. On the left side of the receiver, we can see the latch for the side folding stock which takes the form of a spring-loaded hook. If you have the stock folded, you need to pull rearwards on this hook to release the stock and deploy it. 

The next thing we notice is the stamped dimple, present on either side of the receiver. This is another of these features AK fans will appreciate, as it matches the shape and profile of a real stamped AKS-74U receiver. This was added to increase the strength of the magazine well whilst keeping the receiver thin, light and cheap to manufacture.

Moving to the rear of the receiver we can find an AK side rail, positioned on the left side of the receiver. This rail is intended for AK side mounts and should be compatible with most side mounts out there if you want to add an optical sight to your AKS-74U. This AK rail also allows authentic Russian styled optics to be mounted if you are going for a super realistic Milsim style setup. 

Behind the side rail, we can find the folding button for the stock mechanism. Pressing this in will release the locking mech, and allow the stock to be folded to the left side of the rifle for storage or extreme close quarters work. By design, the stock cannot be folded with an optic or mount installed on the side rail, but fortunately many of these mounts are QD by nature, and can easily be added and removed without losing zero.

Over on the right side is where we can find the controls of the AKS-74U. The charging handle is of a classic AK format and is machined as a part of the mock bolt carrier. The bolt carrier and charging handle are authentically coloured black, matching AKs of the modern era. With the charging handle held to the rear, we can see the adjustable HOP-up slider inside. Moving this piece back and forth will vary the amount of HOP-up applied to your BB and allow you to tune the CM.045 High-Speed for different ammo weights. 

To the rear of the charging handle, we can find the AK fire selector which doubles as a dust cover when in the "safe" position preventing dirt and debris from entering the AEG. This selector is a bit different to most other AEG designs but sits in line with other AKs perfectly with its "Safe - Auto - Semi" layout. This layout was chosen for the original AK47 to provide an easy and quick sweep to set the rifle to semi-automatic and ensure when full auto was selected it was done knowingly and intentionally.

Below the receiver, we can find the steel trigger guard/mag release assembly, and the plum coloured polymer pistol grip. The pistol grip is a classic AK74 pattern grip complete with diamond checkering on either side to ensure the AKS-74U does not slip from your grasp, even in poor weather. The magazine release is accessible from either side, facilitating ambidextrous use for left-handed users and allowing those uber tactical operators who like to shoulder-to-shoulder transition to reload with their left hand (if they practised enough!). 

The magazine insertion method for an AK rifle is a "rock and lock" motion as opposed to a straight insertion, meaning you first need to index the front of the magazine into the magazine well, then rock the rear of the magazine to meet the mag catch and lock it into place. This can take practice, but once you are familiar, the AK platform can be manipulated with impressive speed. This magazine release also allows for a "mag flip" style emergency reload, though we don't recommend that unless you are okay with damaging your magazines!

At the rear of the rifle, we can find its steel folding stock which is the correct design for an AKS-74U of the Soviet era. This stock includes a sling point on the right side which can be used with a single point bungee sling or with a two-point sling using the sling point on the front sight/gas block. The butt plate of the stock is steel but includes linear texture to prevent the stock from slipping out of your shoulder if you wear body armour.

Internally we are in for a real treat with this high-speed variant of the CM.045. The gearbox has been fully revamped and is now equipped with some superb upgrade parts, providing a super snappy trigger response and a positively scary rate of fire. These parts include a high-speed motor, 13:1 ratio high-speed gears, a polycarbonate piston with steel teeth, a silent ball bearing piston head and a double O-ring cylinder head. These upgrades not only make the gearbox ultra quick to cycle, but they significantly reduce the gearbox noise as well, the result being a smooth gearbox that sounds like it takes the hammering of a high rate of fire setup in its stride!

For those with a taste for the AK flavour of AEG who need something short for turning and burning in CQB, or for those looking for a period-accurate late 80s soviet AK, the CM.045 High-Speed does what you need! The combination of the super sturdy CM.045 with CYMA's superb internal upgrades is a match made in AK heaven!
