I have three Colt carbines and will be tearing them down this weekend and wanted to know how can I tell if I have a full auto bolt in it vs. the other bolt. Any pics would be great on a comparison.
There is no such thing as a full auto bolt.
There are many different types of bolt carriers.
Best photo you'll likely find is on Quarterbores Lightning Link page
Cold link to the actual photo, the M16 carrier is on the bottom.
Full auto bolt?
As in assault rifle?
Them thangs is dangerous!
It’s not the bolt.
