So I have recently set up a trust and want to build a high quality AR lower to be my engraved SBR lower. I'm looking for suggestions on which lower to go with. I've considered SanTan tactical and Noveske billet recievers. I'm also considering a billet set. And I'd like the lower to be ambi...any suggestions? (I know functionally all lowers are the same, I want this lower to be able to be handed down since it will be in a trust. I also know forged lower hold up just fine.)
