Delta Deals AR-15 80% Builder Sets Featuring: Davidson Defense Panhead Billet Upper
Mercury Precision Thebe 80% Lower
+ 15" M-Lok Handguard

A builder set is a combination of products put together for two main reasons, to kick start the builder on their journey towards a new firearm or to give upgraded parts to an already assembled AR-15. Our builder sets are special in the sense that they come with an upper receiver, handguard, dust door, forward assist (when applicable), and an 80% lower receiver. This is different from your average builder set thanks to the lower receiver being 80%. This means you don't have to go through the hassle of an FFL due to the fact that 80% lower receivers aren't serialized. You can also stay at home and we will ship these builder sets right to your doorstep. By combining the products we have, these 80% builder sets offer both quality parts at a quality price.

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 Thebe 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 'Thebe' 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. Thin Cutouts have been removed from magwell allowing for a sleek unique design and weight reduction. 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.

15" M-Lok Handguard

One of the best ways to personalize any custom AR-15 build is by choosing your handguard. In today's market, freefloat handguards have definitely become the most popular. Freefloat handguards are made to cover the barrel and are securely connected to the upper receiver using a steel or aluminum barrel nut. Your handguard accomplishes an array of functional applications in an AR-15 build kit including protecting the shooter's hand from the hot barrel, offering the shooter plenty of space to hold the weapon for maximum control while firing, serving as the installation point for sights/optics, providing additional space for other accessories attached, and also, helping create the aesthetic that you want for your build.

It is recommended that your handguard completely cover the gas system of the AR-15, so please take your gas system length into account when choosing a handguard. If you'd rather just buy a pre-designed upper build kit already equipped with a handguard please visit our AR-15 & LR-308 Upper Build Kits page.

About this Handguard: This 15" Ace Series AR-15 Freefloat Handguard from Lakota Ops features an M-Lok rail mounting system and sleek finish.

Mounting System: The Ace Series handguard is equipped with an M-Lok mounting system for convenient and sturdy installation of different accessories & grips in different positions on the handguard.

Cuts: This Latkoa Ops Handguard is designed with diagonal shapes cut into the handguard. This method not only improves the aesthetic of the handguard but keeps it lightweight without affecting the strength or function of the handguard.

Barrel Nut: The Ace Series Handguard comes with a high quality steel barrel nut and mounting hardware

Type of Top Rail: This Lakota Ops Handguard is CNC machined with a cutout across the top handguard with Picatinny rails machined at both ends.
