The Auto-Ordnance M1 Carbine Handguard Assembly is a quality replacement part for your M1 Carbine. Whether replacing a worn part, or upgrading an existing part, this Auto Ordnance part will provide years of service and keep your Carbine in great shape. Note: Made to fit only fit Auto Ordnance firearms made in Worcester, MA. Colors vary between batches. Like original military rifles, wooden furniture on an Auto-Ordnance M1 Carbine varies in wood dimensions and tightness of fit on each firearm. As a result, the size of the gap between the upper handguard and gun stock varies with each rifle.
