Billet AR-15 Beast® Rifle With Colorful Accents and BCG

Firearms enthusiasts love customizing the AR-15. With its many visible parts that readily accept colorful, performance-enhancing coatings, the AR platform is perfect for the gun owner who wants a rig with personality. The color-accented Billet Beast® delivers that right out of the box — no third-party coating company or parts changing required. 

This member of the WMD Guns Beast® line unites several of our premium coatings to give you a fully nickel boron coated AR rifle built on billet receivers and accented with colored BCG, parts kit and charging handle. Choose from 20-plus colors to build a colorful AR-15 that turns heads and delivers legendary performance. 

The Body of the Accented Beast®

Order your custom AR-15 online and know you’re getting a gun built by experts. We start producing your accented AR rifle with aircraft-rated 7075 aluminum billets to cut the upper and lower receivers. The 15-inch free-float handguard includes a full-length Picatinny rail on top and Keymod connection points for accessories.

The receivers, handguard and receiver extension are then treated inside and out with our proprietary NiB-X® nickel boron formulation to give this AR rifle the best corrosion resistance available. Our nickel boron coating stands up to friction, solvents, moisture and anything else you can throw at it — including a 30,000-round torture test. 

The match-grade 16-inch barrel is chrome moly vanadium steel with a government profile, 1:7 twist, and nitride finish inside and out. 

An AR-15 That Comes With Color Accents

This Beast® is unique thanks to its customizable parts. For the BCG, we take one of our full-auto M16 profile models and coat it first with NiB-X®. Nickel boron’s natural lubricity makes it perfect for this part, as the coating greatly increases reliability and makes removing carbon buildup virtually effortless.

We apply the same treatment to the charging handle and small parts — pins, ejection door cover, etc. — and then treat each component with your choice of 20-plus ceramic topcoats. Accent your pre-built AR-15’s parts in Marine Corps Red, Battle Grey, Prison Pink or other popular shades. You can make them all match or choose separate colors for the BCG, handle and parts kit.

We finish out the build with a sleek black pistol grip and a black Ti-7 adjustable buttstock that comes complete with water-resistant storage chambers.

What to Expect From Your Customized AR Beast® Rifle

Every detail of this color-accented AR rifle undergoes consideration by our team. The lower features aggressive magazine well finger grips and the WMD Beast® logo. The barrel includes NiB-X® on the extension for ease of feeding. M4 feed ramps direct ammo into the chamber quickly and flawlessly. A nickel boron coated 17-4 PH stainless steel comp at the muzzle helps you stay on target when firing.

We even take the benefits of NiB-X® inside by applying the coating to critical trigger surfaces, resulting in a smooth, predictable pull and reset.

And it all pays off at the range. Here’s what we got in accuracy testing on this build:

  • Federal 69gr Match Kings = .85 moa at 200 yards
  • Hornady 55gr FMJBT = 1.1 moa at 100 yards
  • Federal American Eagle 55 gr FMJBT = .75 at 100 yards
