Description
The 20″ 5.56 Phosphate + Chrome-Lined Rifle M-LOK Heavy Upper Assembly is engineered for shooters who demand quality, durability, and sub-MOA performance, without compromise. From the forged mil-spec upper receiver to the American-made M-LOK handguard, every component is selected for precision and reliability.
This upper features a 20" heavy-profile barrel with a mag phosphate exterior and chrome-lined bore, offering superior longevity, corrosion resistance, and consistent accuracy over extended firing sessions. A properly torqued barrel nut, using AEROSHELL 33MS anti-seize grease, Permatex 242 on critical components, and a nitrided A2 muzzle device, ensures a secure and long-lasting build. A low-profile steel gas block and rifle-length gas system deliver smooth cycling and reduced recoil impulse.
While the BCG and charging handle are not included, this upper is ready to pair with your trusted components and is backed by a Limited Lifetime Warranty. Whether for precision range work or dependable field use, this USA-made upper delivers exceptional value and performance.
