Did the OP ever choose and build something?
Lots of stuff out there to choose from.
I went with a Wilson Combat 18" barrel.
Not too heavy and sports a 0.875" GB journal that's dimpled for a set screw with a 0.098" gas port. (not published but verified)

Doesn't feel too front heavy without a scope, balances out pretty well scoped at 9.25 lbs.
Accuracy seems good with 193 and 855, cycles nice and smooth with an A5H2 buffer and Tubbs flat wire spring.
I have some 69 and 75 FGMM and S&B 5.56 77 to try out in it.
