Heavy Duty Anodized Billet Aluminum AR15 / M4 Upper and Lower Receiver Set

The 360 Precision HD Heavy Duty AR15 / M4 upper and lower receiver group is precision manufactured in our shop located in Warminster, PA. Completely made in the USA, the upper and lower receivers are machined out of single solid blocks of 7075-T6 billet aluminum. These receiver sets have been designed to provide our customers with a slick side design that eliminates the forward assist to reduce weight. Our custom anodized coating has also been meticulously crafted to be highly durable and provide an amazing finish.
