Compact, ergonomic accuracy is the key to this .223 Wylde upper’s performance. Getting good shot placement and tight groupings out of a 10.5″ barrel is no small feat — which is why this upper’s barrel is forged from high-quality Crucible 416R stainless.
Paired with a .223 Wylde chamber — made to optimize accuracy of both 5.56 NATO and .223 Remington — , this upper’s perfect for driving tacks.
