Check out this Amazing finish on the newest and Baddest Beast Pistol in the line of AR’s from WMD Guns.  The world’s first ARs that are fully shielded by WMD’s proprietary NiB-X® nickel boron extreme coating process, providing unmatched reliability and increased functionality—inside and out! This AMBI AR Pistol has been fully redesigned with dramatic cuts, ambidextrous controls and hammer forged barrels to raise the bar once again on AR performance.

Lesser ARs are much more vulnerable to moisture, corrosion, lubricant buildup, and powder fouling. But the 5.56 AMBI AR Pistol 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.

The pistol comes with two magazines and is ready for extreme performance in any environment, with MOA potential right out of the box.
