You want overweight and oversized look at the SVT ! Lol Also tapco detach mags are very easily obtainable for an sks. I do belive in Canada they all hold 5 anyways ! Lol
Secondly you don't need an optic to hit your target, optics make it easier for some yes. I know some who shoot just as well with Irons as they do optics... I actually have a buddy who refuses to use optics, hunting or target shooting because hes a terrible shot with them for some reason... Great shot with irons.
Everything is just practice, to me a 200 sks is way worth it over the 1600 you spend on a cz to purchase then deck out... I think id be very proficient with the sks after $1400 of ammo through it
Practice makes perfect. (same applies to loading a stripped clip, do it 100 times you will be able to do it fast)
If you need a compensator on an sks you need to worry about hitting the gym more then worrying about the gun !
For me the sks is a little small on the butt, a extension pad fixes that. Other then that, I love them.
