As shown in the red circle.
It is the button for folding the stock; which a fullstock AK74 does not need.
Also, it is missing the rivets for rear trunnion(which has to be there for the stock to be attached to the rifle).
Is there any way for someone else to change the texture or am I going to have to learn how to work with textures and modeling(need to remove the sight rail as well since nobody uses it; and the wood texture need serious improvement)?
