"ROCK-OLA U.S. Carbine chambered in .30M1, imported by Blue Sky of Arlington, VA. This example features the later-war arsenal updates, including an adjustable rear sight and bayonet lug front band. The rifle is fitted with a 15-round detachable magazine. Overall, in very good condition. The metal retains a strong, even finish with honest service wear and light handling marks consistent with age. The bore appears clean with good rifling. The barrel is import-marked ""BLUE SKY / ARLINGTON, VA."" Rear sight and controls show proper military configuration. SN: 6206235."
