Alright kids, I just picked up a new SI Defense billet lower to have as a base for several different uppers. I haven't handled it yet and won't until I'm home again in August but from the pictures my wife sent it looks to be a pretty fair piece especially for the money.
I've read the good and bad about SI Receivers but the bad always had to do with their forged items. Anyone here use their billet receivers and have an opinion?
