Davidson Defense Panhead Billet Upper
The Davidson Defense "Panhead" AR-15 Billet Upper Receiver design was influenced by the iconic Panhead chopper motorcycles, a motor that was popular from the late 1940s and stayed in production until the mid-1960s. Panheads are known for having a unique ascetic, as well as being functional. The classic styling of these bikes that are equipped with the Panhead motor has become timeless and they also have been modified and customized to fit the customers' needs and desires. This is a very appropriate metaphor for an AR-15, especially a billet upper receiver. AR-15's like chopper motorcycles are constantly being modified to fit the customers' needs and wants. So it made sense to derive design inspiration from a product that people interact with the same way.
Precision machined from a solid block of 6061-T6 aircraft grade aluminum the Panhead AR-15 billet upper boasts a sleek and clean design, that doesn't comprise structural integrity while maintaining a slimmer profile for weight reduction. To maintain corrosion resistance the Panhead is treated with a Type 3 hardcoat anodizing. Additionally, the Panhead fits a traditional Mil-Spec ejection port door.

Mercury Precision Carme 80% Lower
The scientists and engineers have been hard at work in the workshop and laboratory creating a billet AR-15 80% lower receiver that is out of this world. The end result of this brain trust is a brand simply known as Mercury Precision. Mercury Precision 80% lowers are machined from 7075 T6 Billet Aluminum, the end result being a very high end product. The goal with Mercury Precision was to create a high end product that does not require a space travel budget to afford.
This Mercury Precision 'Carme' Billet AR-15 80% Lower Receiver has full mil-spec part compatibility ensures maximum customization. This lower can withstand the harshest punishment from any situation using ultra-tough design, precision machined from aircraft-grade billet aluminum for superior strength.

This lower also has a unique, breakthrough design for easy bolt catch installation with a regular punch eliminates need for an expensive special tool. This raw 80% lower receiver can be painted or dipped, allowing for total customization of your lower.
80% Lowers can be made in many different materials that each have their benefits in ease of manufacturing and overall finish when complete.
Particularly 7075-T6 Billet Aluminum is a near-identical alloy used most commonly in modern AR-15 lower receivers. The Suffix "-T6" is an indicator of how the aluminum alloy was heat treated & tempered to give it improved strength and corrosion resistance, before bluing or finishing the lower with a cerakote or anodizing.
Many 80% AR-15 Receivers will be made from Forged Aluminum 7075-T6, 6061-T6, and Composite Polymers.
The lower receiver of an AR-15 is essentially the backbone of the weapon everything else is built off of, it is what makes an AR-15 a firearm. An 80% lower receiver is exactly what it says, it is a lower receiver that is 80% complete. By it being 80% complete it is considered a normal part and not a serialized firearm, so it is legal to purchase without the need of going through a background check or a local gun dealer.

One of the most critical components of any AR-15 custom build is the handguard. In recent years freefloat handguards have increased in popularity. The freefloat handguard covers the barrel and is attached to the upper receiver via a barrel nut. The handguard serves many functions in an AR-15 build kit such as protecting the shooter's hand from being burned by the barrel, offering the shooter something to grip to help steady the weapon, can function as the attachment point for sights/optic, can have additional accessories attached, and adds to the aesthetic appeal of the build.
It is recommended that the handguard completely cover the gas system of the AR-15 so please consider your gas system length when shopping for a handguard. If you wish to buy a pre-designed upper build kit equipped with a handguard please visit our AR-15 & LR-308 Upper Build Kits page.
