New SBR approved today in record time, 14 days.
Also, got my Sionics upper back from Retro Arms Works, had him cut to 14.5" and p/w a YHM Phantom QD flashider. Have several YHM cans pending, planning to primarily use their QD interface. There is a superlative arms AGB under that rail wrap, had him bore out to 0.080 (middy) so that I have ample room to restrict/bleed off.
