Rosco Manufacturing recently announced the expansion of their Purebred line of AR-15 components with their latest offering. The Purebred Upper receiver is a manufacturing collaboration with industry partner American Defense MFG.
Rosco Manufacturing states “Our Rosco stripped upper receivers are designed to work perfectly with our barrels. Every possible option went under the microscope for these uppers in order to tighten the tolerances for the purposes of enhanced accuracy and reliability. We teamed up with our OEM partner American Defense Mfg. and asked them to create the perfect upper that would fully compliment the features of our barrels. The result is a billet receiver that was built to take continued abuse while providing amazing accuracy.”
