R U serious??
I'm thinking I've seen this question before somewhere but not about either the AK47 or 74.
How do you expect the any gun operate if you dont chamber a round after inserting a new mag?
This is a joke or something ,right?
And as for adjusting 'a' scope.....mmnnmm.....thats a good one.....mnmm...No!
I dont believe you can at this time.
Check back in a week and it may be possible for you to adjust 'A' scope.
Not 'THE' scope of course.
But 'A' scope should be available for adjusting.
