Product Description

Madbull's years of enginnering and maching show in the quality of their inner barrels. At Infected Armory we only carry products that we would put into our own guns, which is why we've chosen to carry Madbull's Steel Bull inner barrels.  These are easily the best steel inner barrel you can buy at this price.  Having a tightbore barrel doesn't help unless the bore is smooth and consistent, and that is what Madbull has done with their Steel Bull line of inner barrels.

  • 6.03 mm inside diameter
  • Steel construction for strength and rigidity
  • Square hop up window for compatibility with flat and "r-hop" setups
