Expo Arms Barreled AR-15 Upper Receiver - 5.56 - 16"

Overview

The Expo Arms Barreled AR-15 Upper Receiver features a 16-inch Government-contour barrel chambered in 5.56 NATO with a 1:7 twist rate, capable of stabilizing projectiles from 55 to 77 grains. The barrel is finished with a Parkerized coating for corrosion resistance and includes a 1/2x28 threaded muzzle equipped with a flash hider. The assembly utilizes a mid-length direct-impingement gas system, which provides reliable dwell time and reduced recoil compared to carbine-length systems. It also includes a 15-inch free-float M-LOK handguard for accessory mounting. This upper is designed to install on any standard MIL-SPEC AR-15 lower without modification; please note that a bolt carrier group and charging handle are not included. All components are backed by a limited lifetime warranty.
