Originally manufactured by Standard Products as an M1 semi-automatic carbine, this item has been upgraded by Dillon Precision Products with a full set of M2 conversion components, turning it into a selective fire carbine. Introduced late in World War II, and later a signature weapon of the Korean War, the M2 achieved near maximum level parts commonality with the M1, allowing conversions at the field armorer level to meet unit needs and manufacturers to wait extremely late in the production process to decide if an arm would leave the plant as a M1 or an M2. Blade front and adjustable peep rear sights, an unmarked clamp-on muzzle brake on the "3-44" dated Underwood barrel, Type 3 bayonet lug, 4-rivet handguard, and an unmarked low wood "pot belly" M2 stock. The receiver is marked "20" and "Dillon Prec./Scottsdale, Az." on the left side under the stock, with a "SA" and "MA220" marked operating rod, "A" marked selector switch, unmarked transfer bar, round "A.I" bolt, milled Inland trigger housing, "M" marked M2 magazine catch, "SS" flip safety, "8" sear trip, "I-I" hammer, and an unmarked sear. Magazine absent.

Fine as upgraded to full automatic, with 75% of the arsenal-quality parkerized finish, showing areas of brown and gray patina, scattered spotting, and mild handling marks. Glue is visible on and around the rear sight dovetail slot, with similar residue around the gas piston housing, and heavier spotting/pitting around the piston and the interior of the operating rod. The stock is very good as sanded and cleaned, with mild dents, scuffs, and stains. Mechanically fine. NOTE: This weapon is a National Firearms Act (NFA), fully transferable Class 3, which is registered with the Bureau of Alcohol, Tobacco, Firearms and Explosives, (BATFE) under the provisions of 18 U.S.C. Chapter 44 and 27 CFR part 479.
