Congrads on the AK.
SHOOT IT BEFORE UPGRADING.
Let me repeat myself.
Shoot it before you think about buying wood and upgrading it OR buying rails to upgrade it.
You may decide after shooting it you want rails or wood, or may decide it shoots just fine as is. But shoot it, before making that decision. Do some slow fire and if possible do a mag dump. Shoot it closed and shoot it open.
One day, I shall come back. Yes, I shall come back. Until then, there must be no regrets, no tears, no anxieties. Just go forward in all your beliefs and prove to me that I am not mistaken in mine.
Never cruel or cowardly.
Never give up. Never give in.
