I did, and wanted to try some new magazines in case that was the problem. So I hit the range this weekend. First two 20 round magazines went fine and the problems started trying to load for the 3rd time. I reloaded one of the two magazines, inserted the magazine, and when a released the bolt it jammed. So I will be bringing the rifle down for you to take a look at.
I'm on call this weekend so I'll have to do it next weekend if you're free. Would Sunday the 25th work for you?
