We just got back from the river ,and we took the GSG out and shot the crap out of it.
300 rounds ,all kids of different ammo ,sometimes even mixing the rounds from different makes ,HP ,SP, target fire ,rapid fire ,mag after mag.
107 Deg. Not one MF ,FTF .FTE ,Nothing ,it remained Accurate ,and got so hot from firing and being in the Sun it was hard to hold.
I have been counting ,that is 850 rounds and not one single problem.
I tried to make it screw up ,holding the mag ,shooting it dirty as hell ,nothing.
I guess this speaks for itself.
