We really need a better, closer photo of it than one taken from that distance. At least to show the left side of the receiver. But it looks like you have a Norinco MAK-90. It started life with the potential to have an underfolding spike bayonet but the "ears" for the underfolding spike bayonet assembly were expertly ground off. It looks like the muzzle has been ground/tapered down thereby removing the threads, as well. So, you'd really need to change out the front sight base and gas block with those which aren't neutered. With your rifle, you can go three ways with those parts - those which will give it the original underfoldiing spike bayonet assembly; those which permit facilitation of the "old school" Chinese M1947 bayonet (the one which has the long blade like a Mauser bayonet); or those which permit the facilitation of the Chinese Type II "AKM" style bakelite handle bayonet (you see them in orange, black, and green). You can check with Polytech Parts (do a search on the internet) for parts, find them someday in the sale section of the forums, or search Gunbroker.
A cleaning rod normally would go under the barrel and through a hole in the "lug" under the gas block, and a hole that runs through the lower handguard. Hard to tell with just that photo but yours may be lacking that "lug" for the rod. In any case, you'd need a new gas block.
Your muzzle appears turned down. Although you can thread it again, it won't be of the original 14x1 pitch to facilitate original muzzle nuts and flash hiders. However, some folks use other muzzle devices for their rifles with the different muzzle threading pitch.
Cleaning kits - well, Gunbroker has tons. Just do a search. Original Chinese ones - perhaps Polytech Parts may have one.
