These are extremely lightweight and good for competition builds or race guns. The last method of making aluminum lowers is to cast the lower, using liquid metal poured into a mold.
As the material cools and hardens, the lower is removed from the cast and finished on a CNC machine. During the cooling process, the material forms a loose crystalline structure which means cast lowers are weaker than lowers made by the other two methods. Cast lowers are not widely available, and most quality AR lower manufacturers do not use this method to make their products. The U. This chemical process gives the part durability and improved lubricity.
By placing the lower in a sulfuric acid bath and applying an electrical current, an even layer of aluminum oxide forms over the entirety of the lower. Many other proprietary coatings exist and can impart incredible design effects and color combinations to give your rifle a custom look that is personal to you.
Duracoat, Cerakote, and other popular coating processes are layered on top of an anodized receiver using any colors you want. Flat Dark Earth, Burnt Bronze, Coyote Tan, OD Green, and other commonly found colors are being accompanied now by less battlefield-worthy colors like titanium blue, tungsten grey, pink, red, and many more.
Manufacturers can use these coatings to really up the level of creativity, making custom looks like the Spikes Tactical SANDBOX finish, which features a worn-in FDE color with black elements showing through the finish to create a truly battle-born look straight out of the factory.

For an AR 9, you have two options for a lower: a dedicated pistol-caliber lower or a standard AR lower with a magazine adapter. The first option is simple and reliable, while the second allows you to leverage an existing lower and parts kit.
Part of the enjoyment of owning an AR 15 for many people comes from purchasing a stripped lower, parts, and the required tools to build the rifle for themselves.

Bravo Company Manufacturing has lower receivers with laser engravings available for each branch of the military, and other popular symbols like crosses and coats of arms.
Roll marks and physical aesthetic features can impart a certain amount of personality to your rifle, and with the standardization of the platform making one lower receiver often otherwise indistinguishable from the next, the addition of a cool looking feature could be the basis for choosing one lower over another. And spare parts laying around unused is always a good excuse to go buy another lower receiver and give those lonely parts a home!
