5KU CNC Grip Type 10 for Hi-Capa Tokyo Marui Silver



The 5KU CNC Grip Type 10 for Hi-Capa Tokyo Marui Silver is a complete CNC-machined aluminium grip module for the Tokyo Marui Hi-Capa GBB platform. The futuristic Type 10 design combines a silver-coloured anodised finish with a distinctive diamond-knurled grip texture, an integrated trigger guard and a flared magwell.
The grip comes with several matching parts, including a hammer housing, Type 10 backstrap, magazine release and mounting screws. This makes the Type 10 a comprehensive basis for a custom Hi-Capa, with a focus on both ergonomics and aesthetics.
CNC-machined aluminium Type 10 with diamond-pattern grip
The grip is made from CNC-machined aluminium and features a silver-coloured anodised finish. The sharp lines and geometric shapes give the Type 10 a modern competition and racing pistol look that is clearly different from a traditional plastic Hi-Capa grip.
A diamond-knurled texture has been applied to the key contact points. This diamond-shaped texture provides extra mechanical grip between the hand and the grip module and can therefore help to ensure a more consistent grip on the replica, particularly during rapid bursts of fire and magazine changes.
The trigger guard is contoured at the bottom, allowing the supporting hand to be positioned relatively high on the grip. This is particularly useful for players who use a high, compact grip position.
As it is made of aluminium, the Type 10 feels noticeably different from a standard plastic grip. The material has a solid, CNC-machined feel, but it also adapts more quickly to the ambient temperature and may therefore feel colder in cold weather.
Includes a flared magwell, backstrap and controls
The Type 10 comes as more than just a separate grip shell. On the underside is a flared magwell, which widens the entrance to the magazine well and makes it easier to guide the magazine in during quick reloads.
A matching Type 10 backstrap, hammer housing, magazine release and assembly screw set is also included. This allows various visible grip components to be assembled within a single design.
When using the magwell, you must take into account the magazine baseplates being used. Wide or particularly protruding aftermarket baseplates, in particular, may come into contact with the magwell before the magazine is fully inserted. You should therefore always check this before using the combination during a skirmish.
Compatibility and installation
The 5KU GB-603-SV has been developed for the Tokyo Marui Hi-Capa GBB series. Compatible configurations include the Hi-Capa 5.1, 4.3 and 3.9, as well as similar TM-spec GBB pistols.
That does not mean that every aftermarket Hi-Capa will fit perfectly without any adjustments. Differences between frames, trigger components, hammer assemblies and magazines can affect the final fit.
During assembly, check that the magazine release can move freely, that the magazine locks correctly, and that the trigger can be pulled and reset without any resistance. The hammer housing, backstrap and safeties must also fit correctly and function properly.
Do not force parts together using the mounting screws if they do not fit properly. CNC-machined aluminium is manufactured to high precision, but aftermarket tolerances remain aftermarket tolerances.
Practical insights
The 5KU Type 10 is, first and foremost, an ergonomic and cosmetic upgrade. The diamond texture, contoured trigger guard and flared magwell may improve ease of use, but the grip has no direct impact on FPS, accuracy or gas efficiency.
The stated weight of approximately 159–160 grams makes the grip relatively light for a fully aluminium construction. Please bear in mind, however, that the final balance of the Hi-Capa will depend on the slide, outer barrel, optic mount, magwell, magazine and other accessories.
The Silver version is particularly well-suited to builds that combine several metallic shades. Black, silver, gold and other anodised parts can blend well visually, although exact shades may vary between different manufacturers and production batches.
Who is the 5KU CNC Grip Type 10 Silver suitable for?
The 5KU CNC Grip Type 10 Silver is particularly suitable for players who wish to fit their Tokyo Marui Hi-Capa with a complete aluminium grip module that has a distinct competition or speedsoft look.
Thanks to the included magwell, backstrap, hammer housing and magazine release, the set is ideal for both extensive custom builds and replicas where several standard grip components are replaced at the same time.
For users with no experience of dismantling and reassembling the Hi-Capa lower frame, it may be advisable to have it assembled by an experienced airsoft technician.
