AR-15 and AR-10 Barrels With Performance Coatings

A firearm is only as accurate as its barrel. At WMD, we have high expectations for our guns, so we carry a range of AR barrels for sale that come with premium protective coatings and precision-cut crowns ready to deliver exceptional accuracy. 

WMD Guns barrels are available in numerous configurations so you can find the perfect model for your AR-platform firearm. 

Caliber, Length and Gas System Options

Deciding how to choose an AR-15 barrel comes down to the purpose of the gun. For a capable home defense rifle, you might opt for a lightweight 18-inch barrel chambered in 5.56/.223, or perhaps something in the 10.5-inch range if you intend to buy the tax stamp needed to build an SBR. 

Planning to invest in a suppressor? A .300 Blackout barrel with a twist rate geared for subsonic ammunition will let you take full advantage of those sound suppression capabilities. 

Having the right barrel on an AR-10 or AR-15 will equip the gun to deliver its best possible performance. We have barrels for sale in lengths ranging from 5.5 to 18 inches; with pistol-, carbine-, mid- and rifle-length gas systems; and in numerous twist and caliber combinations for popular rounds like .223 Wylde, 9mm and 6.5 Creedmoor.

Our barrels come threaded for a variety of muzzle devices and have barrel extensions already installed. We also have Nitromet™ and nickel boron barrel extensions for sale separately. 

The Benefits of a Barrel Coating

Gun barrels get subjected to enormous amounts of heat and friction, so even though they’re made with rugged steel, they can only fire so many rounds before they start to lose accuracy. Treating them with a protective coating raises that ceiling and extends their usable life span.

For many years, barrels were treated with hard chrome to minimize throat erosion and reduce fouling. However, modern technology has yielded an even better coating — salt bath nitride, which you’ll find in every barrel for sale from WMD Guns. 

Salt bath nitriding is 30% more effective than chrome and will keep your barrel operational for many thousands of rounds, even when you’re firing premium high-velocity ammunition. 

And because we’re the arsenal of firearms plating technologies, we don’t stop there. We also treat the outsides of our barrels with sleek black Nitromet™ or silver NiB-X®, our proprietary blend of nickel boron for AR barrels and other parts. These finishes yield exceptional protection against scratching, heat damage and corrosion for a barrel you can rely on for years. 

Order Everything You Need for Your AR

At WMD Guns, we demand the best from our firearms, and the products we manufacture reflect that expectation. We sell match-grade barrels for AR-15s and AR-10s that arrive ready to deliver sub-MOA performance and a long life span, plus the receivers, premium bolt carrier groups, small parts and other components you need to build your dream gun.

Whether you need a new .308 barrel to ring steel or a super short 9mm barrel for your home defense rig, you can find it here. If you’re not sure which twist or gas system would be best for your intended application, reach out to our team for assistance.
