Thank you for the advice!

If you plan on using both .308 Winchester on 7.62x51 NATO in a barrel chambered for .308 Winchester for a AR-308 build, do you headspace check for only .308 Winchester, or should you also headspace check for 7.62x51 NATO as well?

Thanks for the replies!

First build. Collecting parts for a Aero Precision .308 build. Any advice greatfully accepted.

I appreciate the replies!!!

Anyone know if the TacOps-Sniper for AR10 charging handle will work with a Aero Precision M5 upper and Aero BCG with forward assist?
