If you ordered an Anderson lower and have already installed a lower parts kit in it, how's it working? Everything fit okay? Which lower parts kit did you use? Just curious. I've been away from the forum for a while, and didn't see the group buy. But I ordered one from Palmetto State Armory and it's due in tomorrow. A guy that has a gun shop in Moore was trying to tell me that these lowers are trash; what's your opinion?
