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 and partners, Tokyo Marui guns are now finally going to be readily available state-side.

"Was able to snag one of these from overseas last November and play a couple games with it. It's the exact same thing as the standard MWS that's been sold before, which means amazing performance out of the box. Only difference is you're paying for a nice DD Mk18 rail. I've run it completely stock on propane, with the only internal upgrade being a new hop-up nub. I've been told to grab an spare nozzle spring, as that's one of the few things to fail when running on propane/green gas, but mine hasn't gotten to that point yet. When I play indoors I switch to duster gas, because on propane I was hitting about 330. For those worried about low FPS, you could always put a longer inner barrel. All MWS come stock with the the same length inner barrel.

If you plan on keeping the original Mk18 rails and not changing anything internally, I highly recommend it. If you want to change out the rails and upgrade internals (in the upper receiver), I'd say save your money and get one of the cheaper variants. TM used a proprietary method of attaching the Daniel Defense rail, so it doesn't install like a regular DD rail. There's an additional barrel nut locking the rail to the barrel, which fastened by loctite. You'd need clamp it down, apply a ton of heat with a heatgun and get special tool to get the barrel nut off. I recommend the TACTICOOL22 M&P 15-22 BARREL NUT WRENCH. There may also be threadlock on the screws holding the gas block in place. After playing with a very temperamental upgraded WE M4 gbbr for almost a decade, the TM ran circles around it out the box. If you got the money to spend, go for it.

-Great accuracy and range out of the box
-Extremely reliable. Can full auto no-problem, but if you're playing with a GBBR, you shouldn't be full autoing anyway
-ZET system guarantees bolt lock when magazine is empty
-Can run on propane/green gas and duster
-Excellent gas efficiency

-Mags are expensive and go out of stock often
-Mags are low-capacity (35). This is a positive for me, coming from 30 round mags
-Rails are very difficult to remove and require special tools
