At 8″ in length, this shorter barrel is great for a compact feel and small enough so it’s always secured in the right place of your home or vehicle. The barrel is turned, glass bead blasted, and equipped with a nickel boron barrel extension.

This allows the shooter to adjust gas flow according to the type of ammunition and suppressor combination being used. This pistol upper is suppressor ready straight out of the box.
