My SKS is currently in Tapco stock like that one ^^^, except I have the Norinco with the tent stake bayonet rather than the blade style bayonet. I have had great luck with mine and the matching magazines. I have read a lot of complaints about the tapco magazines not feeding well, but I think this may be when the tapco mags are used with non-tapco stocks, not sure.
I also have a montecarlo style stock for my SKS that was made by Ramline, I was told. I will probably move the SKS back to the montecarlo style eventually, as it seems better at being a rifle than at being a carbine.
