Heavy Duty Billet Aluminum AR15 / M4 Upper Receiver

The 360 Precision Heavy Duty AR15 / M4 upper receiver is a precision-made masterpiece made to perfectly match our lower receiver. These upper receivers are manufactured in our shop located in Warminster, PA. Completely made in the USA. The receiver is machined out of a single solid block of 7075-T6 Billet Aluminum. These uppers have a slick side design – meaning no forward assist – to provide our customers with a simplistic design that reduces weight. Our custom anodized coating has also been meticulously crafted to be highly durable and provide an amazing finish.
