SPECIAL ORDER
I
The Guardian  Series barrels are precision CNC machined from 4140 CMV steel and completely stress relieved.  The rifling is button cut and air gauged to within 0.0005” for the entire length of the barrel and the bore must measure 0.0005″ concentric to the diameter of the barrel.   All barrels have precision cut chambers, gas ports, and recessed 90 – degree crown . We use a Medium or SPR profile to achieve an optimal balance between harmonic resistance , heat resistance, and weight savings. 
I
The unique deep cut straight or spiral fluting presents greater barrel surface area to facilitate improved air cooling while dramatically reducing weight without compromising the overall rigidity of the barrel.  The 1/8” twist rate will effectively stabilize projectiles between 55gr and 77gr and the 223 Wylde chamber will safely accept both 223 Remington and 5.56 NATO cartridges.
I
All Guardian Series barrels undergo QPQ Black Nitride heat treatment. This heat treatment provides superior corrosion, wear, and abrasion resistance while offering the greatest accuracy potential.  Instead of adding material to the bore (like Chrome lining), Nitride treats the existing steel by imbuing nitrogen into the steel itself. This is done through a liquid salt – bath where the added element greatly hardens the steel a few thousand this into the material.
I
As a treatment, Nitride does not add any materials to the bore, rather it treats the bore a s it came from the factory . Nitride treats both the inside and the outside of the barrel and does not require any oils to provide the best corrosion protection. As a final step, these barrels are treated with a uniform, dark black oxide finish.
