So i'm thinking about plunking down the cash on a M1A. Right now i'm thinking just the standard version which it seems you can get in the $1300 range. Just wondering if any of the other models that SA sells are worth the extra money for what they offer. I want something i can get 4 MOA groups with iron sights...i won't be adding any sort of foregrip, lights, etc to it. I may end up putting a scope but that would be about it. The Scout model is intriguing.....I want something I can hit targets at 500yds...is that doable with this model?
