Built in the United States during WWII, this M1 Carbine pairs an Irwin-Pedersen contract receiver association with period components. The receiver is ordnance steel with a Parkerized/phosphate finish, consistent with wartime production.
The 18-inch Rock-Ola barrel is dated 1-43 and made of ordnance steel. It is fitted with an early no-lug J.M.Q. barrel band, a detail prized by those looking for early-pattern features.
Furniture consists of an oil-finished hardwood stock with a straight grip and full-length profile, plus a butt sling/oiler slot. The handguard is the early two-rivet hardwood style with a sighting groove.
Sighting equipment includes a protected blade front and a rear sight. The carbine operates via a semi-automatic, gas-operated short-stroke tappet system. Capacity is 15+1, and the length of pull is 13.0 inches.
