Hi all, currently finishing an ak build up and am having barrel trouble. The ak hop clip doesn't hold barrel tightly and can still be turned. I've tried a madbull barrel with lonex hop and still get alot of movement. Can I do the top dead centre method or is there an easier way.

pretty common one with a lot of guns.

 

if you "twiddle" it into the right position generally it won't shift, but this is part of the motivation behind aftermarket hop units.
