20" HBar
This is"The barrel" used on the US Military A2 (20”) rifle being issued to our troops. Anvil Arms spends the extra money to give you the proper profile for the entire barrel, even under the hand guards (Where most people do not see it) At Anvil Arms we do things right, we do not cut corners hoping you don’t notice!
All "plain" barrels include a headspaced barrel with extension and gas port hole ONLY.
All barrels with "FSB" include the above and also a forged A2 front sight base pinned in place, barrel nut and forward hand guard cap.
All barrels (Other than Stainless Steel) are first finished with flat black phosphate coating just like the majority of the AR industry does.
Once that is completed, the FSB and associated parts are installed and then the entire assembly is coated with flat black Norell Moly Coat.
This gives our barrels a higher rating in salt water spray corrosion testing than a Stainless Steel barrel.
It also gives our barrels one of the best looking finishes in the industry.
Substitute OD Green, light or dark tan for black Moly Coat $50
Coat Stainless Steel Barrel with Black Moly Coat $50, OD Green, Light or Dark Tan $75
All barrels (Other than Stainless Steel) feature both hard chrome lined chamber and bore for longer service life and greater resistance to corrosion. In fact, a properly hard chrome lined bore has a much longer service life and higher corrosion resistance than a Stainless Steel barrel.
All barrels feature a Mil-Spec 5.56mm chamber. This allows safe firing of most civilian .223 caliber ammunition as well.
All barrels and upper receivers (Therefore all barreled complete upper receiver assemblies) feature Mil-Spec M4 feed ramps for improved reliability in feeding.
All barrels feature the most universal rifling twist rate of 1:9. This allows the end user the widest selection of bullet weights.
