The Centurion Arms MK11 7.62 Billet Receiver Set is designed for an SR-25 pattern semi-automatic rifle. The MK11 receiver set 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. The lower 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 MK11 Stripped AR-10 Receiver Set is what you need to start your next build.
