Everyone knows how good the AR 15 Bushmaster is.  My question is how reliable are the 10 round mags that come with it?

The version that Bushmaster is selling at the moment have been the most reliable post ban mags that I have tried. I don't think you would be dissapointed with them at all.

I've had 0 problems with any of the 10 round bushy mags I've got and shot with.  

They work really well. I have had no problems with them at all.

I just sent one back to Bushmaster for replacement (about two weeks ago). What happened was, I was loading the mag for the first time. Loading normal on the 8th round I heard a slight crack and felt it in the palm of my hand. I noticed that the rear seam had split and the two halves were separating. I stopped there unloaded it and sent it back. It looked like the rear seam welds were not hot enough to bond the two halves together. Other than that they do look to be the best ten rounders I have seen.
