I have a new S&W MP15.  I have 2 PMAG's that work great, 2 aluminum Easymag's that work and a Thermold that I bought at the range, no problems.   I bought 6 CAA polymer countdown mags from Cabella's.  The CAA's have to be jammed HARD to get them to lock in and when they do, they are so tight that the rounds won't feed right and typically jam.  A range instructor took the CAA and put it in their AR and it locked in with no issues.  Has anyone had a similar experience? Is there a fix?

measure and compare, maybe the feed lips are a tad tall?

This is the CAA inserted  that does not fit/feed

Aluminum Cammenga Easymags? Are you sure, I've never seen anything other than steel.

You are 100% correct, it is steel.

Well now you know what mags your rifle likes.  I would invest in more mags that you know are reliable, and not even worry about the other ones.  Give those mags to somebody who has a rifle they will work in.

Thanks for your help.  I really liked those magazines but since my gun doesn't, I will keep searching for Pmags.

Did you paint the S&W logo or factory ?

Looks nice.
