One Horse Complete Upper Receiver 5.56 NATO 10.5″ with BCG and Charging Handle

Overview

The One Horse complete AR-15 upper receiver features a 10.5-inch medium-profile barrel machined from 4150 chrome moly steel with a black nitride finish. Built to mil-spec standards in the USA, it utilizes a 1:7 twist rate and a 1/2x28 threaded muzzle. The upper incorporates a pistol-length gas system, a 10-inch M-LOK free-float handguard, a steel barrel nut, a standard charging handle, and a nitride-finished bolt carrier group. The 4150 steel construction and nitride treatment provide enhanced wear resistance and corrosion protection compared to standard components. The free-float handguard is designed to prevent contact pressure on the barrel, ensuring consistent harmonics. This upper is intended for use with an AR pistol or a legally registered short-barreled rifle lower receiver.
