A Threaded Barrel Designed to Enhance Your Springfield Armory Hellcat The Springfield Armory Hellcat is the pistol that can seemingly do it all, coming with insane capacity for a micro-compact handgun and having the ability to add optics. Why not take your Hellcat all the way by adding a threaded barrel, so you can outfit this do-it-all handgun with a suppressor or recoil-reducing muzzle device? These Springfield Armory Hellcat Threaded Barrels are drop-in designs that make for an easy enhancement on your pistol. Each Springfield Armory Hellcat Threaded Barrel features broach-cut rifling designed for use with all kinds of 9mm ammo, even lead-cast rounds! The barrels are cut with 1/2-28 TPI muzzle threads that are compatible with most 9mm muzzle devices on the market. When you're not running a device, an included thread protector is secured with an O-ring lock. In addition, these Springfield Armory Hellcat Threaded Barrels are a step up from the factory design, coming with special chamfers, radius cuts and other small touches that they don't do at the factory. Best of all, you can choose from a range of different finishes, including stainless steel, black nitride and gold-colored titanium nitride.
