There are reports about the fascination of shorty uppers on ARs. The "sniper" atop the St. Louis vehicle has a scope nearly as along as the barrel of his "Sniper" rifle.
I have read reports that the shorty barrels, ranging from 7.5 - 11.5", have performance problems, as well as distinct noise problems, but agencies are buying them up. Without giving away any SBR issues, do any of you have insights to the shorty barrel syndrome sweeping the "elite" units?
What is your preferred all-around upper length for your AR? Is it the 14.5 with the flash attachment that satisfies ATF? Is it the 16, 18, 20? I know intended use is a factor - assume suburban, urban, and occasionally defending a farmer. Is the shorty worth the consideration, especially if a suppressor or functionality issues can be ensured?
Mosby can hit kill-shots to 600 yards with his 14.5 (I think he shoots a 14.5 and attachment - not certain) - a feat many could not match without a longer barrel.
Does the shorty have its place?
