I bought one when they first started coming into the country. The one I had was 100% reliable with high brass. Weak loads would not cycle reliably.
Mags were hard to find and there wasn't much support for them. Tromix had some gas pucks I believe and maybe a few small things. Recoil was mild and gun was fun to shoot.
I sold it after a year and now have a Veper 12. They did make a few changes to it and if you like the AR style you would probably like it.
