IF someone unscrewed a barrel extension with a reaction rod

it was improperly installed. The tightest flash hider I have dealt with to date was an early SR556 one - have seen those twisted into a corkscrew before they came off. In those cases, best use a barrel vise or 5C collet in the lathe and stay far away from the aluminum.

"Back in my day" (LOL), there were no fixtures readily available and precious few parts for ARs that weren't milsurp, so I used homemade jigs too. But you could buy all the drop in auto sears you wanted at the gunshow for $69... they stopped those in '81, IIRC.
