The Shark Coast Warthog 300-254-1000-20 delivers precision engineering for serious AR-15 builds. This complete upper receiver assembly combines mil-spec construction with enhanced accuracy features for competitive shooting and tactical applications.
What Makes This Different
The Warthog upper features a precision-machined 16-inch barrel with a 1:7 twist rate optimized for heavier 5.56 NATO projectiles. Unlike standard commercial uppers, this assembly includes a free-floating handguard system that eliminates barrel contact for consistent accuracy. The gas system utilizes a mid-length configuration for smoother cycling and reduced felt recoil compared to carbine-length alternatives.Key Features
