Ballistic Ba10 Uppr Rcvr

The Ballistic Advantage BA10 upper receiver is a forged 7075-T6 aluminum upper built to DPMS Gen1 specifications—the standard platform for .308 Winchester AR-pattern rifles. If you're assembling or upgrading a .308 AR, this receiver gives you a precision-machined foundation designed for reliability and durability in field, range, or competition use. It arrives fully assembled with the essential hardware already installed, so you can focus on completing your build rather than wrestling with fitment headaches.

The BA10 features M4 feedramps, a practical choice for smooth, reliable feeding across a wide range of .308 ammunition. The receiver is laser-engraved with T-marks for mounting optics and accessories, and it includes the port door and forward assist. The threaded forward assist roll pin and .2795 takedown pin holes follow DPMS Gen1 spec, ensuring compatibility with parts designed for that platform. One critical point: this is a DPMS Gen1 upper, so it will not work with standard AR15 components—make sure your lower receiver and furniture are .308-pattern parts.

Whether you're building your first .308 AR or swapping uppers on an existing lower, the BA10 is a no-nonsense choice that handles the precision machining so you don't have to. The forged aluminum is tough enough for serious use, and the Gen1 standard means you're working with a widely supported platform for parts and accessories.
