“Beast” – AR-15 Rifle – 16″ 350 Legend


Same tough coatings that define our Beast® line of rifles, on a forged receiver platform.


The world’s first AR fully shielded by WMD’s proprietary NiB-X® nickel boron coating process—inside and out! Lesser ARs are much more vulnerable to moisture, corrosion, lubricant buildup, and powder fouling, but the Beast from WMD is practically unstoppable, thanks to our NiB-X® coating technology. NiB-X® not only guards against friction and wear, it virtually eliminates feeding problems associated with buildup of lubricant and residue.


This rifle comes with
Match-quality 16” 1:16 barrel featuring Nitromet™ salt bath nitride to give the barrel maximum wear resistance and durability that standard barrel finishes just can’t match.

The Beast is ready for extreme performance in any environment, with MOA potential right out of the box.
