So we’re running low on 300BO stuff. I can piece it together but I’d rather you hop on optics planet and snag you a completed aero precision build in fde (I like 2 different colors between 300 and 556 but if you want black that’s cool). 8” barrel with 7” handguard Get a BCG (nickel boron) and radian charging handle With that you’re good to go. Slap it on and shoot. They’re about $425 plus $160 for BCG and $75 for charging handle. That’s cheaper than I can do. 300BO burns all of its power in about 8” so you don’t need a longer barrel. I run an 8” and a 9” and both are great. Supers (120 grains and less ideally) get you terminal performance out to about 125 yards. Subs (180-220 grains) when run suppressed have terminal performance out to about 65 yards. I shoot supers mainly. Aero makes great stuff at that price point. If you grab a completed lower for $300 or so from aero you’d have a complete gun and that would be my preference.
