I'm new to the forum and just got my first Saiga. Question 1 is my windage is off and I tried my AK sight tool and it wouldn't budge. are they just really tight? Is there a safe way to break it lose without breaking it off? Question 2 is every one of the cases are coming out with a small crease about 1/3 of the way down from the top of the case. Anybody know what might be causing this? Other than these 2 issues I love the gun so far.
