If you need a new high quality upper for your AR, your search is over!

The 2A Armament BALIOS upper receiver is precision-machined using a 3D machining process. The 3D machining process enables the manufacturers at 2A Armament to avoid the blocky appearance of many other billet uppers and lowers on the market. The result of 3D machining is a piece of finished work that’s extremely aesthetic.

When selecting parts to build or repair your AR rifle, you will want to be sure that what you choose is of the highest quality. The AR rifle is one of the most popular firearm platforms in the United States and is used in many fields including the armed forces, law enforcement, hunting and home defense. It is also used in competitions and for pleasure shooting on the range. Why would you outfit your prize firearm with anything less than the best?

This BALIOS stripped upper is perfectly compatible with all standard forged products from other suppliers. When used along with the BALIOS lower, it creates the perfect blend between function and good looks.

This upper receiver includes M4-style feed ramps for smooth and effective feeds. The forward assist for this upper is located 1.75 inches further forward to permit better ergonomics. Machined from U.S.A.-certified 7075-T6 plate aluminum, the 2A Armament BALIOS upper receiver will provide you with superior performance.

The BALIOS stripped upper features a hardcoat anodized Type III Mil-Spec finish. The bead blasting of the anodized finish ensures that no glare will reflect off the upper receiver into your eyes.
