In general it is not recommended to dry fire any weapon, as it puts a shock on the firing pin. Use snap caps for this.
When I was in the marines, and received 2 weeks of marksmenship training with the m-14. If my memory serves, we dry fired for 2 days learning to hold position, sight picture, breath control, trigger squeeze, and calling our shots. We had 3 broken firing pins out of 75 rifles, in 2 weeks.
Midway, midsouth, natchez, has them, also gun shows is a good source.
My 5 rnd - 30 rd mags are easily removed using my left hand. Maybe your stock is rubbing on the mag, and needs to be trimed?

Dave has a good point, its a good idea to be behind cover anyway when shooting or getting shot at.
