This Boyds Hardwood Gunstocks Classic Stock was developed using a Yugo Model 59/66 with a blade style bayonet. It is our understanding that this inlet will work for most, if not all, SKS model manufactures or variations thereof with minor fitting. (e.g. spike bayonets will require fitting and the Albanian SKS is an example of a variation that will not fit.) Due to the varying ages, manufacture, condition and wear of SKS firearms, removal of wood or shimming the lower bearing surface at the rear of the trigger guard (fire control group) may be required to achieve a solid lock-up when the fire control group is installed and latched. You will be able to use your factory Iron sights with this stock.
