Underwood M1 Carbine .30 Carbine Semi-Auto Rifle, WWII 1943 USGI, Parkerized, Walnut Low-Wood Stock, Type I Barrel Band, 18 inch Barrel
This WWII Underwood M1 Carbine is a U.S.-made, 1943-production rifle from Underwood's first production block. It pairs early wartime features like the Type I narrow barrel band without bayonet lug, a two-rivet walnut handguard, and a low-wood walnut stock with a later fully adjustable rear sight. The parkerized steel receiver and barrel group, protected-blade front sight, and classic USGI configuration make this a compelling, collectible example. It comes with three 15-round magazines and an OD web sling.

Built by Underwood in 1943, this USGI M1 Carbine falls within the maker's first production block, aligning it with sought-after early wartime manufacturing. The slingwell is marked P-U, identifying the Underwood subcontract code on the stock.
It retains key early configuration elements: a Type I narrow barrel band without bayonet lug that incorporates a sling loop, a two-rivet walnut handguard, and a low-wood walnut stock. The checkered steel buttplate has no trap, consistent with the described furniture.
The sighting setup features a protected-blade front sight with lightening holes in the ears and a later, post-1944 fully adjustable sliding aperture rear sight with windage knob, staked in the rear dovetail. This combination delivers the familiar USGI sight picture associated with upgraded service carbines.
Construction is parkerized steel throughout the receiver/barrel group, with walnut furniture. The action is semi-automatic, using a short-stroke gas piston with a rotating bolt. The standard 18 inch barrel and detachable box magazines support a stated 15+1 capacity.
Ergonomics follow the classic carbine layout with a 13.0 inch length of pull. The overall configuration, early stock and handguard pattern, and Underwood provenance underscore this rifle's collectible WWII character.
