I'm having problems with my bolt holding open on the last shot when I use new 20rnd (brand new) magazines.  It seems to work just fine with the 30 rndrs I have.  Someone told me to let the mags break in.  I did and It's still not holding open.  4 different mags, same problem.  Is there something I'm missing?  Is there any tension adjustment in the mag release button or bolt release that would cause this?

Chances are you will need to pull the mag followers and do some trimming on the skirts to allow the follower to rise high enough in the mag (the feed lip section) to fully raise the catch correctly when the mag is empty.
