Centurion Arms F-15 receivers are manufactured to Mil-Spec tolerances out of 7075-T6 aircraft grade aluminum. After machining, the receivers are anodized per Mil-Spec (MIL-A-8625F) which is a Type III Class 2 hard anodizing process. Still one of the few manufacturers still offering M16 cut trigger pockets in their lowers, Centurion Arms is out to prove you don’t have to charge exorbitant amounts for quality components. Simplicity, function, and tolerances come together to create these great receivers.
