I'm thinking of building a 243 upper for an AR10 that I already have. I have an Aero lower so will probably go with an Aero upper as well. I would like to try the new Hornady 80 grain ELD VT bullet in it. If that doesn't work/shoot well I would try smaller Vmax's. Use case. Killing coyotes that are called in. And if anyone has a 243 AR could they post up barrel length, velocity, and bullet?
Aero upper
SGT of Arms Fore end. (I like having a machined in Arca rail)
X Cal barrel. 18"-22", 1-8" twist, 3R. Rifle, or rifle +2 gas? Threaded for a suppressor.
BCG. I have a RCA BCG that if I send in to X Cal they will headspace the barrel to. So planning to use that.
SLR adjustable gas block.
Off the top of my head those are the main parts. I'm a noob when it comes to AR's.
Any advice on barrel length, gas length, scrap the entire project?
