Good call. I recently took the plunge to 6.5G and was looking at Larue, AA, and PF, all have good creds with the 65Grendel guys. I have an upper in the queue at PF, they have a 12-14 week lead time so it should be here in a month.
Right now, thinking about optics, interested to hear what you'll run on the Larue. Mine will be an 18" mid-weight precision barrel, given the realistic hunting/target ranges I'll be shooting at, I plan to run a lighter 2.5-10x FFP.
