This is a custom 18” stainless steel barrel with a medium contour barrel profile. The barrel is designed to allow a high degree of precision. It is perfect for competitive shooting, varmint hunting, and target shooting. The weight is carefully balanced to provide excellent recoil management.  

The M4-E barrel is chambered in .223 Wylde - optimized to provide the accuracy of match-grade .223 Remington ammunition, yet retain reliability with 5.56 NATO ammunition. It has a rifle-length gas system to maximize performance and minimize recoil.

Our barrels use a 1:8 twist rate, which is optimized for 55-69 grain bullets, but also provides good performance with larger bullets. The barrel uses a mid-length gas system. This reduces felt recoil, which is easier on both the gun and the shooter. 

The barrel features dual indents 180° from the gas hole for easy gas block location and installation. It is recommended for use with the MAA low profile gas block.
