build

Looking for recommendations for my new build. Want a 16in but want some good quality but do not need some space metal build. Just an all around good accurate barrel. Will go under a rap of free floating hand guard.

Picked this up today, a genuine A1 upper. Hope to start a build soon, I'd like to make a period correct build, as much as I can anyway. Triangular handguard, 20" barrel, teardrop forward assist. Will probably go with a modern lower though.
