Here's my budget 458:
-Radical Firearms 16" upper w/ 15"free float handrail Primary Arms sale $460
-Radical Firearms bcg (included w/ upper)
-Anderson lower $50
-PSA lower parts kit $50
-Magpul Moe rifle stock and buffer kit $95
Total build after Tax Tag and Title = $700ish
Will updated with range report when I get in the ammo, optic and get out there. I have used RF upper on another build and it has been flawless so I hope this one is too but at 460, how could I pass that up!
