5KU CNC Aluminium Grip for AR / M4 GBBR -Type 2

The 5KU CNC Aluminium Grip for AR / M4 GBBR – Type 2 is a CNC-machined aluminium pistol grip for compatible AR and M4 platform GBBR airsoft replicas. This Type 2 version is designed for players who wish to replace the standard pistol grip on their gas blowback rifle with an all-metal alternative featuring a modern, sleek design.

The grip is made from CNC-machined aluminium and features an anodised finish. This gives the pistol grip a solid construction and a high-quality metal finish that complements modern custom AR and M4 builds. The Type 2 has been developed for GBBR systems and should therefore not be confused with a traditional M4 AEG motor grip.

CNC-machined aluminium with an anodised finish

For the Type 2, 5KU uses CNC-machined aluminium. With this production method, the shape is precisely milled from aluminium, enabling clean contours and a robust construction.

The surface is then anodised. Anodising creates a protective oxide layer on the aluminium. This gives it its characteristic metallic finish and helps to make the surface more resistant to normal signs of wear and tear.

It should be noted, however, that an anodised finish does not mean that the aluminium is completely scratch-resistant. Intensive use, contact with other metal parts and hard knocks may eventually cause visible signs of wear.

Designed for AR / M4 GBBR platforms

The 5KU Type 2 has been developed for M4- and AR-style Gas Blowback Rifle platforms. According to the product specifications, the grip is compatible with most M4/AR GBBR replicas.

This should not be interpreted as a guarantee that every AR platform is automatically compatible with GBBR. Manufacturers may use different lower receivers, mounting methods, internal components and tolerances. You should therefore always check the exact make and model of the replica before ordering the grip.

With aftermarket parts, a slight adjustment may be necessary in some combinations. Never force a fitting that does not fit correctly whilst the fixing screw is in place.

Specifically for GBBR models and not for standard AEGs

It is important to note that this Type 2 is specifically designed for GBBR systems. A traditional M4 AEG uses the pistol grip as the housing for the electric motor. Consequently, an AEG grip requires a specific internal shape, motor position and base plate.

A GBBR does not have an electric motor in the pistol grip and can therefore utilise a completely different grip design.

The 5KU Type 2 should therefore not be purchased as a standard replacement grip for an M4 AEG, unless specific compatibility information is expressly available for a particular replica.

Modern Type 2 version for custom builds

The Type 2 design makes this grip particularly appealing to players who are putting together a modern custom AR or M4 build. The metal construction complements replicas that already feature CNC-machined handguards, receivers, stocks, charging handles and other aftermarket parts.

As a result, the grip is not just a replacement part, but also a clear external upgrade that allows the replica’s appearance to be further customised.

The difference between Type 1 and Type 2 lies mainly in the design and shape of the grip. The choice between the two versions will therefore largely depend on the desired look and personal preference.

Ergonomics and use

The pistol grip is one of the most important points of contact between the user and the replica. The shape and angle of the grip help to determine how the hand and wrist are positioned in relation to the trigger and receiver.

Whether the Type 2 is more comfortable than the original grip is a matter of personal preference. Hand size, arm length, shooting stance and the replica’s configuration all play a part.

Furthermore, the use of aluminium means that the grip feels different to a standard polymer version. The material has a distinctly metallic and solid feel, but may also be heavier and react more strongly to low or high ambient temperatures.

Weight and balance

An aluminium pistol grip is usually chosen for its construction and appearance, rather than because it is the lightest option. Compared with many plastic AR grips, a fully CNC-machined aluminium version can add extra weight.

As the pistol grip is situated directly beneath the lower receiver, this extra weight is relatively close to the hand and the central part of the replica. The effect on the balance is therefore different from when the same weight is added right at the front of a handguard.

For an ultra-lightweight GBBR build, a plastic grip may make more sense. For a build where an all-metal look and a solid feel are more important, the Type 2 is actually an interesting choice.

Practical insights

The 5KU CNC Aluminium Grip Type 2 is primarily an external and ergonomic upgrade. So do not expect any immediate improvement in FPS, accuracy, gas efficiency or blowback performance.

During assembly, first check that the grip fits correctly against the lower receiver without excessive resistance. Also check for any internal components around the selector and grip mounting. If something does not fit properly, investigate the cause before tightening the fixing screw any further.

Aluminium is also strong and wear-resistant for normal airsoft use, but it is not indestructible. Particular attention should be paid to threads and mounting points during assembly. Over-tightening is rarely an improvement.

Who is the 5KU CNC Aluminium Grip Type 2 suitable for?

The 5KU CNC Aluminium Grip for AR / M4 GBBR – Type 2 is suitable for airsoft players who wish to fit a compatible AR or M4 platform GBBR with a modern metal pistol grip.

The grip is particularly appealing for custom builds where CNC-machined aluminium, an anodised finish and a modern look are key features. Players who, on the other hand, want to build a replica that is as light as possible should carefully consider whether the extra weight of aluminium is desirable.

For owners of a traditional M4 AEG, this is not the recommended version, as this Type 2 has been specifically developed for GBB/GBBR platforms.

Frequently Asked Questions

What is the 5KU CNC Aluminium Grip Type 2 designed for?
The grip has been developed for compatible AR and M4 platform GBBR airsoft replicas.

What material is the grip made of?
The Type 2 is made from CNC-machined aluminium.

What does ‘CNC-machined’ mean?
In this process, aluminium is machined by milling to create the final shape and contours of the pistol grip.

Does the handle have an anodised finish?
Yes. The aluminium has an anodised finish.

Does the Type 2 fit every M4 GBBR?
No, we cannot guarantee that. The grip is stated as being compatible with most M4/AR GBBR replicas, but differences between manufacturers and models may affect the fit.

Will this grip fit an M4 AEG?
This version is specifically designed for GBB/GBBR platforms. A traditional M4 AEG has an electric motor in the pistol grip and therefore uses a different grip design.

What is the difference between Type 1 and Type 2?
The main difference is the design of the pistol grip. Both are CNC-machined aluminium GBBR grips, but the different designs allow you to choose a version that better suits your desired build and personal preference.

Might it be necessary to adjust the fit?
That is possible. With aftermarket parts, there may be slight differences in tolerances. You should therefore always check the fit first before fitting the grip permanently.

Is aluminium better than plastic?
Not necessarily. Aluminium offers a different construction, look and feel, whilst plastic is generally lighter. Which option is better depends on the replica you’re looking for and your personal preference.

Does this grip improve the performance of my GBBR?
Not directly. It is primarily an external and ergonomic upgrade, rather than an internal performance component.

Is the Type 2 suitable for a custom AR build?
Yes. The combination of CNC-machined aluminium, an anodised finish and a modern design makes the Type 2 particularly appealing for custom M4 and AR-platform GBBR builds.

The 5KU CNC Aluminium Grip for AR / M4 GBBR – Type 2 combines a fully CNC-machined aluminium construction with an anodised finish and a modern Type 2 design for compatible custom AR and M4 GBBR builds.
