For military history proponents and guys and gals who like guns, the Browning Automatic Rifle (BAR) is well known! Many were produced and used by military forces around the world from 1917 through the 1970’s.
The COLT MONITOR variant, an improved version of the Browning Automatic Rifle is extremely rare!
Interesting history of the Colt Monitor adopted as the FBI “Fighting Rifle” in the 1930’s.
”Both the R 75 and R 80 failed to achieve any significant sales. However, the R 80 was adopted by the Federal Bureau of Investigation(FBI) as their first (and only) official “fighting rifle”, despite the company only purchasing about 90 R 80s in total. Another 20 or so R 80s went to other police agencies, but that was about as far as sales went. In total, only about 125 R 75s and R 80s were produced over its lifetime, with production discontinuing due to high costs of manufacture.[2][1]”
