We have AR15 and M4 MELONITE barrels including pencil profile barrels, mid-length barrels, carbine barrels and pistol barrels for the .223 cartridge and the 5.56 NATO cartridge. We carry QPQ treated barrels, Nitride Barrels and standard mil spec chrome lined barrels. Most of our barrels are made with 4150 chrome moly or 416 stainless steel (Mil-Spec steel). Our barrels will look great, are lightweight and able to withstand thousands of firings without compromising accuracy. We have barrels from brands including Faxon Firearms, Daniel Defense, Ballistic Advantage, Spike’s Tactical, ODIN and more with options for Wylde barrels that can fire both 5.56 and .223 cartridges (You can fire .223 in a 5.56 barrel, but you should not fire a 5.56 in a .223 barrel due to the difference in pressure).

In addition to standard chrome lined barrels, we also carry Cold Hammer Forged (CHF) barrels that are manufactured by FN. A handful of companies, like Spikes Tactical, utilize CHF barrels from FN. Additionally, Daniel Defense and BCM produce Cold Hammer Forged barrels as well. We have them in stock and ready to ship to your door.
