No problem. However dry firing is a common training technique used by every competitive shooting discipline that I'm familiar with. I'm sure the army expected their shooters that would train with the 82G to dry fire it, that's why they tested its ability to do it. It has a recessed bolt face which keeps the firing pin from hitting the edge of the chamber and damaging it which was a concern with older rifles that were dry fired. Maybe they were worried that the inertial movement and stoppage would somehow damage the firing pin. Firing pins are available from a vendor on Gunbroker should you ever need one.
