Whether you are building a Shot Barrel Rifle (SBR) or an AR pistol, this 7.5-inch barrel from Phase 5 Tactical is a great choice.
This barrel is finished with Manganese Phosphate, which guards against corrosion and gives the surface a uniform, satin black color. This item undergoes several stages of heat treating and thermal stress relief that gives the barrel unequaled durability and the ability to shrug off the stresses of extreme use. The Phase 5 Tactical barrel is also air gauged to ensure the perfect bore diameter.
The electroless Nickel coating on the AR15 barrel is what sets this particular item apart from the rest of the competition. The outer coating offers many advantages over other typed brands. The nickel coating produces an even layer that is impermeable to corrosion of all types. This barrel also confers a natural lubricity to the parts. The extension features M4-style feed ramps for consistent reliability. The 1:7 twist is optimal for 5.56x45 NATO and .223 Remington ammunition.
Give your AR15 the advantages of electroless nickel coating with this innovative component from Phase 5 Tactical!
