jimmyjam101;
I've owned three USA Magazines, Inc 10 shot magazines for over 5 years. I modified one to allow it to hold 20 shots when the law allowed such. The unmodified mag has been utterly reliable through over 4,000 shots. The modified one has worked fine for about 500 shots, neither ever malfunctioning or causing a failure to feed in the Mini-30. I never opened the bag on the third one. These were purchased in 2001 within a week of my acquiring the rifle.
Regards,
