Start your next build on the right foot with a quality AR-15 or .308 Upper Receiver from 5D Tactical. In this category you will find Forged M4 style AR-15 upper receivers and Billet DPMS AR-10 upper receivers. The fit and finish between the upper and lower receiver is crucial to ensuring a quality and accurate rifle build. Our forged AR-15 uppers are machined to extremely tight tolerances, with machined T-markings and finished off with a quality Type III anodized finish. Our billet DPMS AR-10 upper receivers are again machined to very tight tolerances with quality finish options. As the DPMS pattern LR308 is not as standardized as the AR-15 platform, a matched AR-10 Upper and 80% Lower set will prevent headaches in finding matched components when it's time to start your rifle build.
