My buddy had an old one that the body was 2 pieces. The long front section was stamped and the back handle section was a regular forging. The back was aluminum and the front was steel IIRC. The nose of it broke off about 20 years ago and he replaced it with a forged one from M&A parts I believe. No trouble with the new one so far. I have many colt ar15 parts. While none of them are bad and colt may be a standard to judge others by, they're not the best player in the game.
