M3 'pump' mode problem

Recommended Posts

A poster on another forum had an M3 brought to him to see if he could figure out what's wrong with it.

 

Apparently, an attempt to chamber a 3" shell had been made in a 2.75" chamber. The shell was extracted, however, the weapon only functions in 'semi' and will not work in the 'pump' mode. When switched to 'pump' mode, the bolt will not retract far enough to load a shell from the mag.

 

What are some areas/signs of damage to look for?

 

Any constructive advice and assistance is greatly appreciated. This is for an LEO.
