The Badger Ordnance Universal Safety is a replacement for your standard AR-15 safety. The Universal Safety can be installed in a right hand or left hand configuration. The safety is marked with high visibility paint and the off-hand side is raised for visual and tactile indication of the safety's position. Machined from billet 4140 hardened steel and finished in a mil-spec Parkerizing. Notes:The finish on the safety selector is a type III hard coat anodizing and is meant for protection. There may be subtle differences in color because of this finishing process.
