Our 8.9” cold hammer forged ZF-5 barrels are made from 4150 CMV steel with a nitride treatment that is extremely hard, easy to clean, and extremely scratch, moisture, fouling, and corrosion resistant.

They feature 6-groove RH rifling with a 1:10 twist rate as well as 3-lugs and ½ x 28 RH threads that support a variety of muzzle devices, including MP5 flash hiders. Barrels come with a 5.15mm and 5.25mm barrel pin.

These can be used as MP5 barrels as they are compatible with the MP5, SP5, and other full-size 9mm roller-delayed blowback firearms.
