Hi, All. I'm new here. omnipotent, if you're still about, how did this project Of yours from 2018 end up? Have an assembled Aero M5 lower with carbine buffer system and am thinking of getting a fully assembled Aero upper with a full length gas system and an 18 in barrel. Next best option is a mid-length gas system and a 16 in barrel. let me know, thanks.
