Went with a friend of mine to a local gun place. They had stripped Delton(DTI) lowers and Doublestar lowers in stock. They had them for $130. I was shocked they had them, since most places online are backordered and around the same price. Plus the local gun show wanted $200+ for them. Anyway, is there anything wierd with these lowers, like commercial spec stock setups vs. milspec? I know some of the magpul stock kits specify whether you have a commercial or milspec setup. I'm going to get one doublestar and one delton...or should I go with one vs the other? Thanks.
