Look at the Triad buttpack to go on your buttstock. Well made. It uses velcro to attach it on the stock and has extra velcro strips and can be adjusted for height and width. I bought 2 and put the plain one on the Krag and the one with the outside pocket on my mini30/m1a build. Holds a spare 20 rd mini30 mag. Might make it easier to see through your scope. I would think about lower rings, 1/4 is more than you think right next to your eye. And they have a choice of colors. I like mine.
