Basically just taking the AKS-74u Folding stock, and putting it on a AK-74, simple to do and can then be used for the Soviet Special Forces to further differentiate their gear, and an N variant for scopes of course

And a AKM is easily do-able too, recolour the wood parts to be a dark reddish colour, use the vz. 58 magazine and a new muzzle brake and you have an AKM, you can put a GL on it, and would be available to the FIA as another option
