Hey guys, After sending my rifle back with it's new 223 accessory barrel,it has returned! :grin: The firing pin was apparently flattened and was hanging up in the primer thus making it hard to open (Sounds crazy but it works now). The firing pin was replaced at no charge :grin: , and a new forearm fitted to that barrel took care of the loose when open problem :grin: . So my new 223 is back up and running! Time to find a load it likes,any suggestions?-Thanks,Jeff
