Ever wondered why you see so many in the wild pics nowadays, which show USSOF using 10.5″ uppers?
Many of these photos depict magnified optics, or environments where you’d expect a 14.5″ to be used.
Ever noticed that the increase in these pics coincided with the roll out of the Surefire SOCOM 556-RC?
This can is one of the reasons why at least half of USSOF run their 10.5″ M4A1 uppers, regardless of environment.
