Welcome to the group!
That appears to be a Choate stock set which was put on by the importer after getting the rifle in an attempt to be different. Back in the early 1990s (the one in the photos is one of the few date marked as 1993) importers were trying to figure out how to sell the AK variants. Too soon after Nam kept people from wanting one of those "commie rifles". Today their value has skyrocketed due to the import bans.
Whether it has a slant cut on the receiver or standard should really not make much of a difference as it would still be a really nice shooter. Chinese AK variants had arguably the best trigger feel of any factory produced AK variant.
