The SKS-M ( and D ) uses the normal AK mags not the Tapco duckbills, so you can stock up on AK mags. It is a bit harder to find the M with the Monte Carlo stock. Im not a fan of the more common thumbhole stock which is used also on MAK90s as well. I am a fan and owner of the AR platform too. Your work is very nice Southern by the way.Love the SKS, but it's hard to find one with and get extra detachable mags.
I went AR15 because that's what every cop car has In the trunk.
