M1944 Hyde Carbine

However, due to the rising production during World War II, the initial design was too expensive for mass production, and its weight defied the concept of a 'Light Rifle'. The M1944 Hyde carbine came with a quick barrel change device similar to the MG42. It used pressed steel components to ease production and reduce weight, making it versatile, reliable, and easier to carry.

The M1944 Hyde submachine gun came with an uncommon quick-change barrel system. The bolt is similar to the Solothurn MP-34, where the spring is contained within the buttstock. Photos of the Hyde gun appeared in the first edition of The World’s Assault Rifles by Daniel Musgrave and Thomas B. Nelson, published in 1967. No known examples of the M1944 Hyde carbine remain in existence.
