Of course! Although, the Kalashnikov offers 30+ round capacity with no tinkering.

RE Tinkering:

Yes, but a quick disassembly and simply dropping the integral 10 round mag out allows you to use 30 and larger mags in the SKS as well. You just put it back together without the integral mag, and viola...

And there is a mod that can be done to allow the SKS to use AK mags as well. But as you said, that requires tinkering. :^)
