Does the stock have a rubber butt pad on it? I put a cushioned version on my AR chambered for .50 Beowulf, and it helps quite a bit.
But yeah, why is the rear sight so far forward? Did you have a big-butt scope mounted at one point?
Yes, it has a rubber butt pad. I mistakenly put the back sight up too far because when I first put it on I didn't know how.
