Whose 18" free-float model would you recommend most for around $600? I'm attached to that barrel length; maybe I shouldn't be. Mostly I'd be using it for hunting and target applications.
That said, I'm debating whether it's better to build (in order to, say, splurge on a melonite barrel and nice trigger) or go with a ready-made setup. Since my dad ordered a 6.8SPC upper assembly from Hardened Arms a couple weeks ago, the build process has piqued my interest.
