50 Beowulf Uppers
Extreme Big-Bore Power: .50 Beowulf Complete Uppers
Unleash the ultimate stopping power of the AR-15 platform with our selection of .50 Beowulf complete uppers. Also known by the metric designation 12.7x42mm, this caliber was engineered to provide devastating short-to-medium range lethality that rivals the legendary .45-70 Government. These complete upper receivers are a true "plug-and-play" upgrade, allowing you to transform any standard mil-spec lower into a heavy-hitting brush gun without the weight and bulk of an AR-10. Whether you are hunting feral hogs in thick timber or looking for the hardest-hitting "Thumper" for the range, our .50 Beowulf uppers deliver unrivaled terminal ballistics in a compact, semi-automatic package.
Every .50 Beowulf complete upper assembly in our inventory is purpose-built to handle the unique stresses of big-bore fire. To ensure 100% reliable cycling, our uppers feature specialized enlarged ejection ports and heavy-duty .50 Beowulf bolt carrier groups (BCGs) with reinforced extractors and recessed bolt faces. We utilize barrels with optimized twist rates to stabilize heavy 300gr to 400gr projectiles, if paired with high-efficiency tank brakes will significantly tame felt recoil. Because the .50 Beowulf functions with standard 5.56 magazines (utilizing a single-stack follower), transitioning to a 12.7x42 upper is the easiest way to achieve maximum knockdown power on the modern sporting rifle platform.
