Installed the Star one on my rifle last week.
MAG brand mags feed perfect, TM feed perfect, KA feed perfect and CA feed perfect (all the mags I have right now to test).
The feed tube is cast metal instead of molded plastic and can be removed and taken appart if something jams or gets dirty. Nice feature in my opinion.
Oh, metal mag catch too. locks positive every time. I filed the underside round because inserting the mags was a pain from factory.
