"SI-B" blade front and "GE-Q" two-leaf rear sights, with an undated IBM barrel, Type II barrel band, blue round bolt, stamped trigger guard, "EP-B" button safety and a "PR-B" magazine catch. Low-wood stock, with a 2-rivet handguard, "T" stamped wrist, "crossed cannon" on the right side, oval oiler cut, "SCB" sling cut and a checkered buttplate. With a hand-numbered matching shipping box, stamped with Army nomenclature and bearing a shipping label from the Letterkenny Army Depot.

Excellent plus as issued, with 98% plus of the correct original parkerized finish, showing some minor cycling and edge wear, along with some mild handling marks. The stock is also excellent plus, with minor pressure dents. Mechanically excellent. One will look a long time to find a better IBM M1 Carbine.
