Sorry.
I believe they only made a few cosmetic and minor mechanical changes to the AB-10 (TEC-9).
My suggestion would be to do a search on the internet since IntraTec is out of business.
I have a friend who had major problems with his TEC clone (a Kimmel AP-9). He had an
"Non-intentional discharge". To his credit he was following safe handling rules and had it pointed away from an people. It took out his sliding glass door though!!
FYI It wouldn't feed for anything, this time it did but wouldn't
fire or eject. He had to take it home that way. He figured he'd have to work on it as he didn't want to ship it (still under warranty) in that condition. When he tried to get the bolt open, it fired - BANG!
