Hey guys, I got a new SKS. every part of it is so so stiff. trigger is heavy a creep. The bolt is heavy and sometimes it just does not fully closed. The rifling is so sharp and as new as my 50 rounds Savage 308. All those are fine for me, but the trigger hammer spring is way too strong. Every time when I dry fire it I can feel whole rifle is shaking. It sounds much louder than some other SKS in the store. After I put a scope on it, I am able to clearly see the vibration of reticle. My question is: does it influence my accuracy? How many loops of spring should I cut?
