The M1 Carbine was originally issued in 1942 without a bayonet lug. This period did not last long as by 1943 all M1 Carbine rifles were being fitted with a bayonet lug. The original M4 bayonet was similar to the M3 fighting knife with a wood grain leather grip, blackened steel blade, razor sharp blade, and sturdy crosspiece. This attractive reproduction 1943 Style M4 bayonet is perfect for recreating the look of a period correct M1 Carbine.
