14.5" M4
This is "The barrel" currently used on the US Military M4 carbine being issued to our troops. While many companies only cut the notch close to the end of the barrel, 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) where it is made smaller to allow for some weight savings. 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 $25
Coat Stainless Steel Barrel with Black Moly Coat $50, OD Green, Light or Dark Tan $75
All barrels feature the most universal rifling twist rate of 1:9. This allows the end user the widest selection of bullet weights.
NOTE:
On the 14.5” barrels we can permanently install a Yankee Hill Machine Phantom flash suppressor to bring the total length to the 16” minimum legal requirement. This is a $60 option.
When assembled onto a rifle this barrel (Without the above mentioned permanent flash suppressor modification) would constitute a "short barrel rifle" and would therefore require NFA registration with the ATF. Installing this barrel onto a non-registered gun is a felony violation punishable be serious prison time and huge fines. If your interested in having a barrel of this length and doing so LEGALLY please see our NFA FAQ pages and then contact us for more information about registering your weapon to allow you to use barrels of this length.
This barrel could be used without restriction on an AR type receiver that was built and factory registered as a pistol. Again, see our NFA FAQ pages for more information on this. Anvil Arms offers factory registered pistol receivers. These are laser engraved “Registered Pistol”.
