I picked up 2 Aero AR10 lowers a few years back. Turned 1 into a 6.5cm that I ended up selling off to a buddy that was looking for one. The 2nd lower sat in the safe untouched until last year.
I built the lower first. Used a CMMG lpk, a mil spec trigger I worked on & it now breaks @ 3.5lbs with a Wolf heavy hammer spring. I wanted a rifle length stock & went with a LUTH-AR stock. Had a left over Ruger grip from my RPR .22 & used it. I have a gray rubberized magpul on order.
The upper is a Pro fab, with Ballistic Advantage BA Hanson .308 16" SS mid length gas barrel, Toolcraft double ejector BCG, Aero adjustable gas block, Warhammer charging handle & Right to Bear 15" handguard. Running a YHM flash hider for my YHM R2 & R9
Optics ... Vortex Strike Eagle 1x8, Aero cantilever mount, offset XS Sights.
