Mossberg 500 Shotguns - Learning How They Work?
I am semi-retired and I am taking a self-passed and self-taught Armorers course on Mossberg 500 Shotguns. I hope to become a part-time light Gunsmith in the future.

There are over 60 quiz questions covering this firearm and I have answered most of them. During my study and research I am having some problems related to some of the following quiz questions. Either I am not sure of the correct answer or I have conflicting answers.

Can you help me determine the correct answers for these few final quiz questions?

Thanks for your help.

Note #6. What moves the locking block (bolt lock) up and down into the closed or locked up position?
a) The action bars
b) The slide (bolt slide)
c) The cartridge stop
d) The elevator

Note #8. When the firearm is locked up and the locking block (bolt lock) move up, where does it lock into?
a) The receiver
b) The action bars
c) The recess in the barrel extension
d) It doesn't, it moves down

Note #9. What gun part locks the bolt and bolt slide into position when the gun is locked up and ready to fire?
a) The action bar lock (action lock)
b) The extractors
c) The elevator
d) The mainspring guide

Note #10. The 500 has two extractors, which one of the extractors has a negative hook?
a) The right extractor
b) The left extractor

Note #12. What causes the elevator to rise and fall?
a) The primary cartridge stop
b) The trigger housing
c) The bolt slide
d) None of the above


Again, thanks for your help!

I recently had to replace several parts in a Mossberg 500 while attempting to resolve a problem cycling spent shells. (Issue still present, so it will be going on vacation shortly.) I found a YouTube video of someone disassembling a Mossberg 500 that helped me. If memory serves, they also showed some of the function as they were disassembling/reassembling it. Maybe it will prove helpful, either to you or someone else:
