I have the SBR forms approved, and am now ready to get the 9mm AR upp and .45 AR Upper cut down for eventual suppressors.
9mm - what barrel length? I was thinking of 8"-10" - have read a lot, but no one seems to have THE answer - will be shooting 147 grain subsonic almost exclusively through a suppressor.
45 - Looks like 7"-9" again may be the best bet. Again, will use subsonic (duh) and mostly through a suppressor.
Any ideas, guys? I want to optimize my accuracy and fps, but given my subsonic parameters and suppressor use I want the barrel as short as reasonably possible to get the ballistics performance I want.
