Hop Systems - 6.01mm Stainless Steel Tightbore Inner Barrel
We spent months developing what we believe to be the perfect stainless steel inner barrel. We wanted to make something you would be proud to own! We've made the highest quality barrel incredibly affordable as well! These barrels are cold-forged in the highest quality SUS304 Stainless Steel, a better bore quality every steel inner barrel on the market, features an extended square window for the best possible r-hop contact, and made into a tight bore with the highest tolerances! This tight bore barrel is even better quality than the legendary PDI steel barrels.
