If you plan to have your Hi-Capa built or upgraded, choose a Tokyo Marui base: it is the standard for which most parts are designed. An AW Custom (Armorer Works) is a good replica, close to this standard, but each upgrade may require fitting. This guide compares the two bases depending on what you want to do with them.
This article is part of our Hi-Capa airsoft guide.
The difference at a glance
| Criterion | Tokyo Marui | AW Custom (Armorer Works) |
|---|---|---|
| Market role | The benchmark: "TM spec" parts are designed for it | A clone close to the Marui standard; many AW parts are advertised as Tokyo Marui compatible |
| Stock slide | Polymer on the base 5.1 | Depending on the models in the HX range: check the spec sheet |
| Range | 5.1, 5.1 Gold Match, 5.1 D.O.R., 4.3 Tactical Custom, 4.3 Dual Stainless, 4.3 D.O.R. | HX series, in several formats and finishes, including optic-ready versions |
| Upgrade | The widest choice of parts, with the fewest modifications | Often possible, fitting required on the hop-up chamber and hammer and sear group |
This table shows general trends. Even within a brand, two generations of replica can differ: always check the exact version.
Why the Tokyo Marui base remains the benchmark
The Tokyo Marui Hi-Capa GBB serves as the model for most parts manufacturers. Shops therefore indicate "for Tokyo Marui Hi-Capa" or "TM spec". A Tokyo Marui base accepts the widest choice of parts with the fewest modifications. This is why our Hi-Capa builds are assembled solely on a new Tokyo Marui base.
Details of the range can be found in The Tokyo Marui Hi-Capas: 5.1, Gold Match, D.O.R. and 4.3.
What to check on an AW Custom
Armorer Works uses the Tokyo Marui architecture. The points to check first, before buying a part, are those where tolerances make the difference:
- The hop-up chamber and the nozzle: the nozzle must fit exactly into the chamber. A difference of a few tenths is enough to cause leaks or double feeds.
- The hammer and the sear: buy them as a complete set, designed for your base. See Steel hammer and sear kit for Hi-Capa.
- The magazines: a magazine from another brand may fit without feeding correctly. Test it empty before the first game. See Hi-Capa magazine: Marui, WE or AW, gas or CO2.
- The slide: a "TM spec" slide often fits, but the fitting on the rails can be too tight or too loose.
The brand-by-brand comparison, with WE, Vorsk and KJW, is in Hi-Capa Tokyo Marui or clone: which parts are compatible?.
Which base according to your project
| Your project | Recommended base |
|---|---|
| Play stock, without planned upgrades | Both are suitable: choose based on the finish, format and magazine availability |
| Upgrade gradually yourself | Tokyo Marui: the fewest modifications for each part |
| Have it built by a workshop | Tokyo Marui preferably; an AW close to Marui remains buildable after inspection |
| Red dot | A version designed for optics (D.O.R. at Tokyo Marui, optic-ready at AW). See Red dot on Hi-Capa: D.O.R., platinum or chassis mount |
Do you already have an AW?
It remains a good base for a workshop build, provided its dimensions are close to the Marui standard. The workshop checks the fitting of the parts before assembling them. The fully assembled builds, however, start solely from a new Tokyo Marui base. For a quote, specify the brand, model and version of your replica.
Our opinion
To play as is, the best base is the one for which you can easily find magazines. For a custom build, the Tokyo Marui base saves time with each part, and it is the one we use.
Frequently asked questions
Is an AW Custom Hi-Capa compatible with Tokyo Marui?
AW is close to the Marui standard and many of its parts are advertised as compatible. Still, check the hop-up chamber, hammer and sear group and magazines.
Tokyo Marui or AW for a first Hi-Capa?
To play stock, both are suitable. To upgrade later, the Tokyo Marui accepts the most parts with the least fitting.
Do AW magazines fit in a Tokyo Marui?
Often, but feeding is not guaranteed. Test empty before the first game, or keep magazines from the replica's brand.
Does the BDU workshop build AW Hi-Capas?
Yes, if their dimensions are close to the Marui standard: the workshop checks the fitting before assembling the parts. Ask for a quote by specifying the model.
