I think my son at least talked about eating Ramen Noodles for a
month to afford to buy his.
Oh, you meant something else: diet the gun. Again, my son bought the
Yugo SKS for its curio and relic military collectable status, precisely
for all the features that make it ... hefty. If your goal is a light
sporter, there are better starting points than a Yugo SKS. Given
that once these historic arms are gone, they are gone, alerations
should not be permanent.
Yugo stocks are usually pretty nice wood for a military gun.
Before taking it afield for hunting, I would probably just remove
the bayonet (and the cleaning rod since the bayo retains the rod)
to save a few ounces carry weight (and strange looks).
The grenade launcher puts the muzzleblast significantly further
from my ears, so that I would keep. Besides, it appears to be
a "semi-permanent assembly" to the barrel.
