A direct replacement of the original PolyTech Spike Bayonet installed on AK47 rifles manufactured in the early 80's and imported by KFS Industries Inc. (Kengs Firearm Specialty). This is the famous under-folding "Pigsticker" Spike bayonet seen on several Chinese type 56 AK47. The early model AKS-762 PolyTech produced in Chinese State Arsenal 416 came standard with the "Norinco" style blade type bayonet. Although still seen on some earlier production Chinese AK47 rifle models, the Spike type bayonet was standard issue on Later production AKS-762 AK-47's produced in Factory 386. Completely machined from steel and includes the superior blued finish the PolyTech AK47 is known for. The bayonet is installed to the front sight housing using a rivet (Bayonet Pin Part# 70-00-29) to hinge the Spike on the FSB (Front Sight Base). The spring-loaded handle allows the bayonet to be deployed quickly and locked in place. The Spike Bayonet will not work on the Legend Series PolyTech.
