"bought the type 89 35 round magazines for the MTR 16 January 2024.

give the type 89 magazine a tap on the bottom until you hear a satisfying click.
easily falls out of the rifle when you hit the mag-release.
good weight on it.

i suggest going on ebay and getting 3rd party speed loader attachment for the odin speedloader. it'll make life so much easier when loading these magazines.

"The best magazines for MWS! Always go for Tokyo Marui mags for MWS as other brands are full of problems. The maximum capacity of standard mags is 35-36rds, not 30rds.

I have a warning though: an original TM speed loader is required to load these magazines. I had tried many speed loaders and neither work as flawless as Marui speed loaders. If you don´t want a TM speed loader, the MWS itself comes with a stick loader that works amazingly well but is not as convenient as the speed loader, considering you want to reload your 35rds magazines in the middle of the game.

- Best reliable magazine for MWS.
- Accepts propane and green gas out of the box. (Gen2 & Gen3)
- TM brand speed loader required (and they aren´t cheap)
- Low capacity mags (but we all know what we get into when entering the GBBR world)
Personal preference:
- Heavy.

"These magazines are by far the most reliable ones I’ve ever owned they don’t leak and if they do all you need is
Some techt gunsav and some plumbers tape on the inlet valve
