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 receiver has a heavy-duty, integral trigger guard. 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.

12" M-Lok Handguard
A handguard is the most functional and unique part of any AR-15 build. Freefloat handguards offer an incredible reduction in weight and includes many features such as mounting systems M-Lok/Keymod or both! Having the barrel in a freefloating handguard allows you to retain zero and have an increased level of accuracy. And having the ability to add grips, laser systems, lights, and bipods will further increase the capability of your next 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.
