FN C1 Rifle Bayonet The C1 Bayonet was the standard bayonet used on the C1 and later C1A1 assault rifles, finally replacing for good the spike design in use since 1943. The web frog was only produced in green; by the time of the adoption of the FN in the late 1950s, 1951 Pattern gear (and the soon to be introduced 1964 Pattern) was the official pattern used by the Canadian Army. The C1 Bayonet could also be fitted to the C1 submachine gun. Knife bayonet for use on the C1 variant of the 7.62 mm. NATO caliber FN–FAL assault rifle. The C1 is the L1A2 as manufactured in Canada. The C1 differs from the Australian L1A2 by having the pommel secured to the tang by rivets, where the L1A2 pommel is brazed to the tang. The C1 assembly slot in the pommel is T-shaped, where the L1A2 assembly slot is straight, as shown in this comparison image. The C1 bayonet was produced 1956-66 by Canadian Arsenals Ltd., Long Branch, Ontario, Canada. The number on the crosspiece face is the part number portion of the NATO Stock Number for bayonets. The scabbard is the No. 5 Mk. I.
