Universal M1 .30 caliber carbine

More than 426,000 carbines were manufactured by Universal Firearms over a 25 year period from 1961 through 1986. This was 10 years longer and more than three times the quantity manufactured by any other commercial carbine manufacturer. In the beginning the first Universal Firearms carbines were 100% compatible with surplus GI carbine parts, their carbines included many of these parts. As with every other commercial carbine manufacturer, as surplus GI carbine parts became scarce, Universal Firearms began using commercially manufactured substitutes. Unlike other commercial carbine manufacturers, some of the commercially manufactured parts used by Universal Firearms were eventually compatible with the Universal Firearms carbines only and not interchangeable with their surplus GI counterparts.
