Not suitable for SS or FRT
AU shipped and packed this lower perfectly. The quality is typical Colt. My only complaint with this lower is it has a denial block in the trigger pocket. If you plan to use an SS or FRT trigger pack this lower will NOT work without modification. AU should really put that in the description. It may be common knowledge with Colt users but I was not aware until after i purchased it.
