Unlike Tokyo Marui Airsoft guns of the past, the M4A1 MWS (ZET System) rifles now feature metal receivers instead of all polymer as well as fully licensed trademarks to add to the realism of these replicas. Combined with Tokyo Marui's high quality internals and stock dependability, these rifles are great to skirmish out of the box or as a base for high performance projects.
The new ZET System is Tokyo Marui's latest entry into the GBB rifle market featuring an action similar to the venerable Hi-Capa design as opposed to standard gas M4 systems. The ZET System has been designed to not only be much more gas efficient, but it has been designed with durability and longevity in mind thanks in part to its short travel roller style hammer; this hammer design greatly reduces the cyclic wear on your bolt, hammer, and valve knocker. Additional improvements include a steel bolt locking plate which addresses a common issue with standard gas M4 systems where the bolt stop suffers from accelerated wear and quickly loses the last round bolt locking function.
While Tokyo Marui has been around for a long time in Asian markets, their availability has been limited/restricted due to licensing and importation issues; however through Evike.com and partners, Tokyo Marui guns are now finally going to be readily available state-side.

Common Product Questions
Find quick answers about our airsoft products, shipping and policies.
Will this part fit my platform?
Compatibility is product-specific. Check the brand, model, size, and platform named in the product description, such as Tokyo Marui Hi-Capa 4.3 or 5.1, AAP-01, Umarex/VFC Glock, or a particular AEG gearbox type.
Similar-looking parts are not always interchangeable, so contact our team with your exact model if you are unsure.
Do I need tools or gunsmithing?
That depends on the upgrade. Simple external parts may be straightforward, but internal upgrades can require disassembly, reassembly, adjustment and testing.
If you are not comfortable working inside your airsoft gun, our team offers professional tech and custom-build services.
Can LA Airsoft install this part for me?
Yes. We can build and upgrade Hi-Capas, AAP platforms, and rifles. Choose your base gun and parts, then add the appropriate tech service.
The current custom-build service states that builds are normally completed in approximately 3 to 5 days, with the team reviewing the selected parts for compatibility.
How should I maintain this product?
Regular maintenance helps preserve performance and reliability. Keep the product clean, follow the manufacturer’s lubrication instructions, and properly manage batteries, gas systems, and internal components. More advanced repairs or internal servicing should be handled by an experienced airsoft technician.
How quickly will my order ship?
Orders without preorder items are typically packed the same day when placed before 4:30 p.m. Central Time. Please note that occasional delays can occur during especially busy periods or when staffing is limited.
Will this part increase my FPS?
Not every upgrade increases FPS. Some parts are designed primarily for reliability, cycling speed, weight reduction, or gas efficiency. When a product has a tested FPS claim, it should be stated in the listing.
