The designation “Blue Sky, Arlington, VA” found on M1 Carbines signifies a specific importer mark. These markings indicate that the firearm was imported into the United States by a company named Blue Sky located in Arlington, Virginia. The presence of this mark on an M1 Carbine denotes that it was originally a U.S. military weapon that, after its service, was likely sold to a foreign country and later re-imported back into the U.S. civilian market.
The re-importation of these firearms provides collectors and enthusiasts access to a larger pool of surplus military rifles. However, the presence of the importer mark, particularly the “Blue Sky” marking, has historically been associated with concerns regarding the quality of the firearm’s condition. Some imported firearms were known to exhibit wear and tear, potentially requiring maintenance or repairs to ensure proper functionality and safety.
