I have a new to me ross rifle m10 and when you close the bolt - yes the lugs fully engage - and pull the trigger it will not fire. Its almost as if the trigger needs to move further. I can have the bolt semi closed and pull the trigger and the bolt will move to the fully closed position and the firing pin drops. I have examined the exterior of the trigger mechanism and the exterior of the bolt and everything looks correct and doesnt look like any broken parts. Please help.
