*This upper assembly does not come with Bolt Carrier Group and Charging Handle
Whether you are building an AR15 or planning to upgrade your current AR15, the Aero M4A3 style complete upper is an excellent choice. Featuring a 16-inch 5.56 barrel with pinned FSB and a two-piece polymer handguard, this complete upper with A2 front sight offers classic USGI (United States Government Issue) look.
The Aero complete upper with A2 front sight is made from high quality Aero Precision parts, ideal for building or upgrading your AR15 with affordable but quality parts.
Installation takes only a matter of minutes; you could potentially be shooting with your new M4A3 style complete upper the day it arrives in the mail.
If you were to purchase the parts in this complete upper separately, you would ultimately spend more money than it is currently being sold for.
You also receive the pride of having purchased a part for your AR15 that was made in the United States of America.
If you are building your AR15 from scratch, please note that a BCG and charging handle are not included in this complete upper. This allows you to choose the ideal bolt carrier group and charging handle for build. If you are upgrading an existing AR15, the BCG and charging handle may be used from the previous upper.
NOTE: For the protection of our customers and various safety and legal liability reasons, we do not accept returns on ammunition, firearms, barrels, or any product that contains a barrel. Defective firearms, barrels, any product that contains a barrel (ie, complete AR-15 uppers, complete pistol slides, etc.) and ammunition must be returned to the original manufacturer for warranty service. You can have peace of mind that all firearms, barrels, complete uppers, and ammunition that we sell are brand new from the manufacturer, and have never been used, installed, or modified.
