I just ordered a blem stripped upper yesterday from Ammunition, Magazines, Rifle Parts, Bulk Ammo and Rifle Accessories - Palmetto State Armory and went back to their site today to find they had blem stripped lowers for $70 so yeah, I got one of those on the way now too! I'll be dedicating this build to a good friend of mine who took his life a couple weeks ago. He had just completed a full auto SBR shortly before his death. I'll be having some custom lasering done on the gun in memory of him. Build thread to come soon!
