Armalite M-15
Armalite M-15 Caliber : 5.56 × 45 mm NATO Armalite 3-Gun Rifle Review- M153GN18 By: University of Florida 3-Gun Team Due to financial difficulties, Armalite sold the AR-15 to Colt in 1959. Later, as the AR series became popular in the civilian market, every factory wanted to produce AR for sale, so Armalite decided to re-enter the market. However, since they no longer had the ownership of the AR-15 name, they slightly modified the original design and launched this civilian semi-automatic rifle under the name of M15.
