Mid State Firearms - Ar15 Mfg
Did this a few weeks ago and wanted to share. Upper uses the BMS shrouded 10.5 barrel that a suppressor will fit inside, but the welded shroud keeps it a non-SBR. Lower is a MSF billet with Maxim CQB stock and a rise 3.5lb drop in trigger. Will probably do a video soon to show how the BMS uppers work. They're pretty cool.
