Chambered for 5.56x45 NATO, originally derived from .223 Remington, 5.56 NATO is the standardized and most popular cartridge developed for the AR-15 platform. Utilizing a .22 Caliber projectile, the low-mass, high-velocity cartridge allows superior weapon handling with manageable recoil and high accuracy. With a wide variety of ammunition choices on the market, 5.56 NATO chambered AR-15s are 'multi-caliber' and can reliably fire both 5.56x45 NATO and .223 Remington cartridges.

This A2 flash hider has a classic and effective design. Flash hiders are essential in position concealment and keeping your vision clear; especially in low-light situations. This design has a flat bottom which means the gasses won't kick up dust because they are directed up and to the sides. It has a 1/2x28 thread pitch and a Manganese Phosphate finish to protect it from corrosion. This A2 flash hider is a classic because it simply does a great job.
Sometimes it can be a challenge to find the proper equipment for left-handed (or as we call it: 'off-handed') shooters. With this left-handed billet upper receiver, it doesn't have to be. This stripped upper receiver does not have a brass deflector or forward assist. The streamlined design and slick side help set this upper apart. This billet upper is great because it has better thermal properties, is stronger, and looks phenomenal.
