I've had my Tac-15 for several years now, and need to ask a this question. Do I need to remove the buffer and spring from my ar lower when assembling the Tac. Noticed that the buffer retainer is broke and have had an issue with the cranking block.

This is also a great opportunity to replace and worn cocking cable on the sled and also make sure the pin in he sled is well seated and locked in place.
