No problem there as you're probably already figured out. When I get home I'll see if I can attach the PDF I got from Redding and failing that if you give me your email I'll send it to you.
I still haven't cut or recontoured my gas tube to fit in the TP555 gas block so I'm sure I can come up with some drama there and then how to get and keep the AR running with the right subsonic load. Stand by, I'll come up with some other mini series.
Thanks for your help.
