I bought a stripped Larue billet AR-10 lower last week. Allegedly it will be delivered in 2 weeks. I’m wanting to build this up as a do all multi-purpose “battle rifle”. I want accuracy but not a lot of weight and not looking for extreme precision. It will probably get a LPVO, a 16” barrel and be used with a Griffin RSTA. It will more than likely be chambered in .308 due to ammo “availability” and when I get a 6.5 I’ll get a bolt gun. I’m a noob with AR-10s other than a fam fire with a SR-25.
-I know the Larue lowers are M-110/SR-25 pattern and Larue, KAC, LMT uppers will fit. Are their any brand uppers I have over looked?
-What lower parts from 5.56 lowers will work?
-Which CH and BCG to get?
-Receiver extension, buffer and spring? Is an A5 RE a thing with these?
-Are triggers AR-10 specific? Probably get a Geissle or Larue.
-Should I build an upper re group or just save up for a KAC or Larue factory built upper? Not really considering LMT for this due to weight.
