I have just received an Empire Rifle in 300 WM. It is my understanding it is a variation on a Mauser action. It appears to have a 3 position safety similar to a Win model 70. The rifle cocks and fires, the bolt removes and installs easily, but the safety seems stuck in the fire postion. I have not been able to move it in anyway. It seems stuck forward to fire. Am I missing some feature ot technique or is it broken ?
