From the manufacturer

The Centurion Arms C4 5.56 Billet AR-15 Stripped Lower Receiver is not like your typical, over-designed, flashy billet receivers. The C4 receiver from Centurion Arms is designed to have all the features you need and none of the useless design aesthetic that drives up prices for no other reason than to stand out at the range. Machined from 7075-T6 aluminum and type III class 2 hardcoat anodized to military standards for a long service life of reliable use. It features a flared magazine well that isn't so large as to get caught on gear when you are carrying it but will greatly increase your reload speeds. The enlarged, integrated trigger guard allows for use of gloves and eliminates a potential weak point. All sharp edges have been de-burred by hand for a smooth premium finish and all dimensions are inspected for accuracy. The Centurion Arms C4 Stripped AR-15 Lower Receiver is what you need to start your next build. Features: CNC machined from billet 7075-T6 aluminum Class III Type 2 hardcoat anodized black Compatible with Mil-Spec parts Flared magazine well Integral winter trigger guard Receiver tension screw Fully de-burred by hand Dimensional accuracy inspected 90deg safety selector markings Multi-caliber Made in the U.S.A. Weight: 9.5 oz. Another feature of this billet AR-15 lower receiver is the rear tensioning screw that takes out any wobble between the upper and lower for better accuracy and a more solid feel. The safety selector pictograph markings are designed for 90deg safeties and is compatible with ambidextrous safeties as well as other Mil-Spec and aftermarket components. All components, material, and packaging are made in the United States and the overall weight of this lower is 9.5 ounces.
