5KU PK-3 pistol grip for GBBR AK

The 5KU PK-3 Pistol Grip for GBBR AK is a CNC-machined aluminium pistol grip for compatible AK GBBR airsoft replicas. The design is based on the well-known Zenitco RK-3 style and offers an interesting upgrade for players who wish to replace their standard pistol grip with a robust metal version featuring a modern Russian tactical look.

The grip is made from CNC-machined aluminium and features a black finish. The contoured design, with finger grooves and textured surfaces, helps to maintain a clear and consistent hand position. Thanks to its all-metal construction, the PK-3 also feels considerably more substantial than many standard polymer AK grips.

CNC-machined aluminium structure in RK-3 style

Whilst many standard AK GBBR grips are made from plastic, 5KU has opted for CNC-machined aluminium for the PK-3. This gives the grip a solid construction and a distinct metallic look.

The design is inspired by the Zenitco RK-3 and features the characteristic angular design, contoured surfaces and finger grooves. This makes the grip an excellent fit for modern AK builds that combine several Zenitco-style parts.

It is important to distinguish between the two products: the 5KU PK-3 is an RK-3-style airsoft aftermarket part and not an original Zenitco RK-3.

Contoured grip for a consistent hand position

The PK-3 has a clearly defined grip profile with finger grooves and textured contact surfaces. This ensures that the hand is positioned correctly around the pistol grip.

This can be useful during dynamic airsoft situations where you frequently switch between different stances. A consistent hand position can help you feel more confident when handling the replica.

Ergonomics is, of course, a personal matter. A heavily contoured grip may be more comfortable for one player, whilst another may prefer a more neutral pistol grip without pronounced finger grooves.

Specially developed for AK GBBR platforms

The 5KU PK-3 has been developed for compatible AK Gas Blowback Rifle platforms. This distinction is important, as the design around the pistol grip on a GBBR differs from that of a standard electric AK.

In a traditional AK AEG, the motor is usually located in the pistol grip. This GBBR version is not designed for that purpose and should therefore not be regarded as a universal AK grip.

There may also be differences in mounting, dimensions and tolerances between different AK GBBR manufacturers and generations. You should therefore always check the exact make and model of the replica before ordering the grip.

Ideal for a modern AK build

The PK-3 really comes into its own on a modern or Zenitco-inspired AK build. Its aluminium construction and angular design complement replicas that are otherwise fitted with modern handguards, railed dust covers, stocks, optic mounts and other tactical AK accessories.

The black version can easily be combined with both all-black replicas and two-tone builds featuring, for example, wood, Bakelite-style magazines or various earth tones.

Anyone wishing to retain a classic AK look is likely to opt for a traditional pistol grip. The PK-3 is clearly designed for the more modern end of the AK spectrum.

Weight and balance

Due to its aluminium construction, the PK-3 is heavier than many standard plastic pistol grips. Depending on the version and the method of measurement, it weighs around 225–240 grams.

That extra weight is situated relatively close to the receiver and the user’s hand. As a result, it has a different effect on the balance than, for example, a heavy metal accessory fitted right at the front of the handguard.

For players who want to build their GBBR as light as possible, an aluminium pistol grip is not necessarily the most logical choice. In a build where construction, appearance and a more solid feel are more important than the lowest possible weight, the PK-3 actually comes into its own.

Internal storage compartment

The handle features an internal storage compartment in which small accessories can be carried, provided they fit within the available space.

The compartment can, for example, be useful for storing a small accessory or other compact item that you wish to keep with the replica. However, do not automatically assume that the compartment is completely waterproof; additional protection is advisable for moisture-sensitive items.

Practical insights

The 5KU PK-3 Pistol Grip is primarily an external upgrade that alters the appearance, material and feel of a compatible AK GBBR. As such, do not expect it to result in any immediate improvement in FPS, accuracy or the replica’s internal performance.

Before fitting, always check that the grip fits correctly at the mounting point. Aftermarket parts may sometimes require a little adjustment due to differences between manufacturers and production tolerances. Never use the fixing screw to force a poorly fitting grip into place.

You should also bear the weight in mind. An all-aluminium grip feels noticeably different from a lightweight plastic version. For a realistic-feeling or all-metal AK build, this may actually be desirable, whilst players who are trying to save every gram will probably opt for something else.

Who is the 5KU PK-3 Pistol Grip suitable for?

The 5KU PK-3 Pistol Grip for GBBR AK is particularly suitable for airsoft players who wish to externally upgrade a compatible AK GBBR with a metal pistol grip in the Zenitco RK-3 style.

The grip is particularly appealing for modern Russian AK builds where a CNC-machined aluminium construction and a tactical look are important. For players with a standard AK AEG, this is not the right version; the PK-3 is specifically designed for compatible GBBR AK platforms.
