Ruger’s Infantry Rifle
While Bill Ruger would have loved to sell the Mini-14 to the U.S. military in some format– indeed, it emulated the Garand/M-14 only in .223– the only uniformed use outside of national and local police units was to arm the Royal Bermuda Regiment for about 25 years.
While we have covered the subject in the past, The Armourer’s Bench just released a great video on the subject, complete with several video clips of the RBR using their Minis.
