Our Assessment: The M1 Carbine was developed and produced after WWII started. Over 6 million were made by a number of U.S. companies to assist with the all out war effort. The M1 Carbine was widely issued to U.S. Military Forces which numbered over 16 million during WWII. The M1 Carbine contributed greatly to U.S. efforts during WWII.
The International Business Machines Corporation (IBM) was one of several contractors who tooled up during WWII to produce M1 Carbines in support of the war effort. IBM only produced about 5.7% of the total number of WWII M1 Carbines. IBM’s low production numbers make IBM M1 Carbines quite desirable.
This IBM M1 Carbine was made back in 1943. It has been rebuilt using a mix of USGI parts but still retains several IBM parts. The most notable (for collectors) is the “I.B.M. CORP.” marked barrel. The rifle was purchased through the Civilian Marksmanship Program (CMP) and comes with a Certificate of Authenticity. This collectible wartime military rifle should keep you smiling out at the range. It also comes with a magazine and a sling so all you need is some ammo. Good luck.
