think the buffer keeps the hold open from working. watch a few vids and it seems easy enough to just hold the bolt open to disassemble. factory hold open is sonny anyways but I still use it when I'm not intending to fire the rifle. i started the auto release mod but didn't dremel out enough material on mines.
liked all the vids I watch on the td but good ole att throttled me down a couple days ago <img src="/ubbthreads/images/graemlins/mad.gif" alt="" />.
