I used a MDT Field stock on my RRA 300BO and love it. A Bell&Carlson would be a good choice to. Of course there are a ton of other brands as well. Boyds are good but heavy. The KRG Bravo is nice. All depends on budget but for me, the Magpul is last on the list. Nothing wrong with them, I just don't care for the way they look and not sure how much better than what you have now.
