I got all my parts from MAA (sponsor on this site) They were a big help when I called and told them what I wanted. I got my trigger, Tromix DIY guard, Ace stock (they have a choice of sizes), folder, front grip and my receiver block (the block is still on back order). About as close to a kit as you can get with good parts. I just finished my changeover yesterday. I'm just waiting on my receiver then it's BOOM time!
