Microbest chromed BCG – These are some of the finest bolt Carrie groups I’ve ever got my hands on I’ve had them in the past but this deal is stellar excellent service speedy shipping these guys are tier 1.
Amazing – It says blem but it’s in perfect condition
Chrome BCG “blem” – Mid State Firearms is a first tier source for quality products. This BCG is a high level upgrade.
BCG Chrome “Blem” – Best value on top quality BCG’s period. I have the phosphate as well. Just as outstanding too. Can’t go wrong with either choice. Just buy either, worth your hard earned money.
