Great to see this moving forward Mike,...and hope everything is going great for you. I would go 10rders, for the obvious reason that these will sell like hotcakes in the 10rd limit states and the length is perfect. 14rder because...what's the sense in tooling up for just 2 more rounds and length wise, may be just about max for tacticool. And then the 20rder for the crazies that don't care about length, weight,....drag trails....
