Big Beast™ AR Rifles

The Big Beast™ line of AR-10 rifles and carbines brings you some of today’s most popular cartridges in a platform perfected by WMD Guns. With these builds, we’ve taken the details that make our Beast® line great and scaled them up to create guns that are ready for anything.

Nickel Boron AR-10s With Top-Class Details

The Big Beast™ AR-10 is for sale online, chambered in .308/7.62×51, 6.5 Creedmoor and 8.6 BLK. Other chamberings may be available on request, and we offer our rigs with extensive customization options. 

Opt for a battleworn AR in .308 from the Survivor Series for an adaptable workhorse you can tailor to your needs. If you want something ready to ring steel at range, check out our nickel boron match-grade 6.5 Creedmoor with a precision buttstock from Luth-AR. 

WMD Guns AR-platform firearms come with premium furniture from some of the industry’s top manufacturers, including Magpul and ERGO. You’ll also find offerings with Hipertouch fire control groups, Magpul magazines and tactical fitted cases for a rig that’s ready to go right out of the box. 

With their aggressive styling and billet or forged aluminum construction, these beasts represent the best of American manufacturing capabilities. 

Why the Big Beast™ Line Outperforms the Competition

WMD Guns uses a proprietary blend of nickel boron called NiB-X® to give our firearms an edge. Our Big Beast™️ match-grade AR-10s feature a NiB-X®️ coating inside and out to take full advantage of this material’s capabilities. 

Nickel boron is hard, slick, and resistant to heat and chemical damage. Carbon buildup can be wiped off this surface with a cloth, eliminating the need for harsh solvents and making it perfect for the dirty-running nature of the AR’s direct gas impingement system. Even better, this lubricious coating makes our nickel boron AR-10s far more reliable than lesser firearms because it resists timing issues due to fouling.

Our NiB-X®️ coating comes with a lifetime warranty guaranteeing it against wear-through, chipping or peeling. You’ll have a nickel .308 or 6.5 Creedmoor sleek enough to look like a safe queen and rugged enough to handle heavy use.
