16" 5.56 Black Oxide Barrel with EFFIN-A

Build a Firearm

Chambered in 5.56 with a 1:9 twist, our 16" barrel is made of 416R Stainless Steel and comes Black Oxide coated for superior resistance against rust, corrosion, and just about whatever you can throw its way. With the carbine length gas system this is the perfect barrel for those wanting to build their own standard length AR15 Carbine. Add extreme value to this deal by getting a MkII EFFIN-A along with your new Black Oxide Barrel. Our MkII Effin-A Compensator is designed to allow users the ability to adjust the manner in which the gas exits from the weapon. The Effin-A Compensator MKII features 8 columns and 3 rows of exit ports that can be either opened or closed through the very simple use of set screws. The exit ports are not threaded completely through to eliminate the possibility of the screw being over turned into the chamber. This feature also allows the screw to "bottom out" increasing tightness and ensuring that it will not work itself out under the pressure of the gasses being released by the weapon.
