Retro(ish) AR-10(ish)

[mr.tickle]

I was looking at building a retro type (FSB, Carry handle, 20" barrel, etc) 308 AR. Will a standard .750 AR-15 FSB fit a 308 barrel? I do not see any kind of dedicated AR-10 FSB. Will the A4 carry handle sights work with the 308 cartridge and fit on a 308 upper? Thanks for the help in advance.

Depends on the profile of the barrel as to whether the gas block will fit. Wanna go retro for an AR10? Get a carry handle upper with the charging handle on the top of the inside rather than in the rear. It looks like an upside down trigger. Add wood furniture and waffle pattern mags.
