I want to take a 16" AR15 barrel and cut it to 14.5" and that would be covered by the AR15/AR10 barrel threading $65.00, To make it an exact replica of a factory 14.5" would I also need to select M4 .700 X .700 muzzle step $60.00 or is that included in the $65.00 thread service? Sorry if a dumb question.

Thanks dmtsc

If you want an exact replica yes you would need the 700x700 step as well. On the plus side your whole barrel gets reparked.
