CMMG ZEROED HUB MNT DT .578X28 BLK

The CMMG ZEROED HUB Mount is a direct-thread suppressor adapter designed to bridge your .578x28 muzzle device to CMMG's ZEROED HUB suppressor system. Built with a nitride finish for durability and corrosion resistance, this adapter lets you quickly swap suppressors without losing zero—a critical feature for shooters who run multiple cans or need fast reconfiguration. It's the kind of precision component that separates a solid suppressor platform from one that actually works the way you need it to.

Direct-thread mounting has become the go-to for serious shooters because it's compact, rigid, and eliminates the mechanical tolerances that sometimes creep into QD systems. The .578x28 connection is common on modern AR platform rifles and many precision builds. The 1.375x24 HUB interface connects you to CMMG's modular suppressor lineup, letting you future-proof your setup as your arsenal grows.

Whether you're a precision rifle shooter looking to maintain shot-to-shot repeatability or someone building a cohesive suppressor ecosystem around the ZEROED HUB platform, this adapter does one job exceptionally well: it threads securely onto your muzzle and accepts CMMG suppressors without wobble or shift. Nitride-coated steel construction handles the punishment of field use and regular maintenance without breaking a sweat.

Frequently Asked Questions

What rifles and barrels does this mount fit?

This adapter fits any barrel or muzzle device with a .578x28 thread. It's commonly found on modern AR-platform rifles and precision builds. If you're unsure about your current setup, check your barrel specs or existing muzzle device threading before ordering.

Will this adapter work with non-CMMG suppressors?

This mount is designed specifically for CMMG suppressors and components that use the 1.375x24 HUB interface. Do not attempt to force incompatible suppressors onto this adapter.

Does this adapter affect zero when swapping suppressors?

The direct-thread design and rigid HUB interface are engineered to minimize shift between suppressor changes. However, always verify zero after any component change, especially if you're shooting at distance.

Is this a complete suppressor system?

No—this is the adapter mount only. You'll need a CMMG suppressor compatible with the 1.375x24 HUB interface to complete your setup.
