@RedRiverII more guys needed to work on there rifles than didn't from what I have seen. But the guys here have cracked the issues. I have 2 kinds of patience, little and none. I started here by modifying an AR 15 from PSA and it worked out. But I got my RRA Standard Operator off the shelf. I have assembled a couple of M5 16" and 14.5 and replaced the Aero recoil system with Armalite. What do you do before retirement? I never stop learning here.
