First of all, let me say that the warning issued with the rifles is not because of problems that are encountered with only our rifles. That list was a direct result of contacts with other firearms manufacturers as well as magazine and ammunition makers who were all reporting the same problems. The fact of the matter is, there is a lot of garbage ammunition out there, and there's a reason why cheap is cheap.
AR's are not cheap by any means. Even a used no-name is likely to run you many hundreds of dollars. They are precision rifles, and function as such. Spend a little more on ammunition, and the end result will be worth the difference.

As a side note, there are some types of ammo listed on our spec sheet as being unsafe, and there are some that just plain don't work well. You are free to make your own decisions about what you want to use, we just feel that you need to be aware of the risks associated with doing so.
