The Diligent Defense Co Zilch Hub Adapter is a titanium muzzle device adapter designed to bridge Cherry Bomb-style flash hiders to standard suppressor hub threads. If you're running a can with industry-standard 1-3/8x24 TPI threads (also known as ASR or Bravo), this adapter lets you use your existing Cherry Bomb muzzle device without sacrificing suppressor compatibility or adding unnecessary bulk to your setup.
Built from 6-4 titanium, the Zilch Hub is engineered for hunters and shooters who demand lightweight, durable hardware. At just 1.5 ounces, it won't shift your balance or slow your swing. The adapter adds only 3/16 inch to your overall sound suppressor length, preserving the handling and sight-in characteristics you've already dialed in. The hex-shaped external geometry makes installation and removal from your suppressor intuitive—no special tools required, just a standard wrench.
Compatibility is broad: this adapter works with any Diligent Defense Co suppressor, plus other cans featuring the same 1-3/8x24 TPI hub threads. That flexibility matters when you're building a modular suppressor ecosystem across multiple firearms. Keep in mind that standard Cherry Bomb muzzle devices protrude roughly 1.5 inches into the blast chamber, so factor that into your baffle design expectations. For best results, torque the adapter to your suppressor at 25 foot-pounds.
