This 16-inch barreled upper pairs WMD's in-house coating expertise with quality components to give you a rugged, reliable build. 350 Legend has gained real traction as an efficient, low-recoil hunting round with excellent accuracy potential—and this upper gives you a solid foundation to achieve it.
WMD Guns manufactures many of their components in-house, including their proprietary hardcoat anodizing and advanced nickel-boron coatings. This upper arrives with a complete bolt carrier group, charging handle, forward assist, and handguard already assembled. The NiB-X coated charging handle and BCG resist corrosion and enhance reliability; the gas system uses a Nitromet-coated gas tube and low-profile gas block for dependable cycling without being bulky. A muzzle brake is included to help manage recoil and muzzle rise.
Fit this upper to any standard AR-15 lower receiver you already own, and you've got a capable hunting or range rifle in a less common, genuinely useful caliber. The 16-inch barrel strikes a balance between velocity and handling in timber or from a truck. All the hard work is done—just bolt it to your lower and go.
