That is exactly what a bayo lug looks like after it has been ground off. |
WRONGThat is not from the bayonet lug being ground down.
Chinese AKMs came in 3 flavors regarding bayonets before the 89 import ban.
1 standard AKM lug for a modern type bayonet.
2 standard AK lug (Type III milled) but on the stamped reciever. (Think Poly barrel assemblies floating around the for sale stuff lately)
3 cruciform bayonets.
The type III bayonets lock on to the front sight block, not to the gas block. The gas block merely has a loop for the cleaning rod and the rear of the bayonet handle simply slips over the barrel and rests on the front of the gas block.
The cruciform bayonets fold like an SKS bayonet. They had the cleaning rod loop like the type III BUT it was cut in half as to make clearance for the bayonet when folded. This is what you have. Your gas block is untouched, originally made for an under folding bayonet. Your FSB is not a match for this. If you bought the under folding bayonet FSB that is being sold on GB by PARS Inc then you would have the proper setup for the gas block. The gun (if correct) would also have a small notch cut out of the lower hand guard retainer (the metal part) and the hand guard would be relieved as well.
