In addition to this, Faxon’s heavy flute-shaped barrels are known to give immense rigidity for the weapon’s weight. You can also try the ballistic advantage barrels, and they range in three different types, such as Modern, Performance or Premium. The Hanson Barrel is another choice, and guess what, it’s shoulder-less. To avoid any issues, you have to use the 16-inch barrel.
