F-1 builds some of the best rifles in the business and shoot as good as they look, if not better. The guns are made from Aluminum Billet and come with a lifetime warranty from F-1 since they are all factory built guns we sell. No cheap Anderson parts and Frankenstein junk builds like some dealers sell. 100% F-1 parts as we are a master dealer and the only F-1 mega store in the nation. Please look at pics to see the build sheet for this rifle.
