Lower Assembly Parts
Upgrade your AR with many of the same top-quality, American-made parts we use in our line of Beast rifles.
Most of these parts are coated with our proprietary NiB-X® nickel boron coating process (indicated by the NIBX prefix in the individual part numbers). WMD’s exclusive NiB-X nickel boron coating helps any part resist friction, wear, and fouling. What’s more, the incredibly lubricious surface of WMD’s coated parts means that they can function smoothly without frequent oiling. All our components are made in the USA to OEM-grade tolerances.
You’ll also find our exclusive NiB-X coated mags, plus selected parts for Glock pistols.
From time to time we’ll even list discounted parts that have slight cosmetic blemishes…still fully operational and functionally sound, but not quite pretty enough to satisfy our picky inspectors!
(Please note that some parts may best be installed by a qualified gunsmith.)
