Piston SBR First Shots Short Overview

This video from Classic Firearms explains the meaning of forge markings found on AR-15 upper receivers. Instructors Matt and Jason clarify that these markings indicate the manufacturer of the raw forged aluminum blank, not necessarily the quality of the final product. They detail common forge marks like the keyhole (Cerro), splintered 'A' (Anchor Harvey), and square (BAFE), explaining that the machining process by the final manufacturer is the primary determinant of quality and adherence to mil-spec standards.
