Master Sgt. Monte Ealy, 28th Civil Engineer readiness and emergency management NCO in charge, uses a 12-ton shop press to forge the body frame of a custom made AK- pattern semi-automatic rifle replica in Rapid City, S.D., Dec. 11, 2012. Ealy says that rifle building is an art that requires a good amount of ingenuity, a drill press, a 12-ton shop press, and a variety of other tools required by craftsmen gunsmiths.
