I know this has probably been answered somewhere, I just can't find it. My new Max 1 .223 will only fire 1 in say 10 tries. The firing pin does not even touch the primer when it does not fire. Nothing has been altered on this one. The trigger has not been touched. I manually tripped the pin and it is sticking out the bolt face. I watched as someone else fired it and I can see the back of the pin move when the trigger is pulled???? I can't figure this one out?
