Skans AR Decision Tree
1. If you don't have any military style 5.56 then fork out the $$$$ now for an AR-15, you don't want to be caught without one!
2. If you only have one AR - don't sell it. Who cares what prices are, you have yours and all is good.
3. If you have more than one AR, use your least favorite(s) as trading fodder to upgrade to a better AR, if you can find something you really like better.
4. If you have one AR and another .223 semi-auto like a Sig 556 or Mini-14, then sell all of it and your tacticool accessories too and buy an FN SCAR. Then you are done because now own the very best .223/556 you can buy.
