The Diligent Defense Co HUB DTA 1/2x28 Direct Thread Adapter DTA12 is a precision-engineered mounting solution that allows HUB-compatible suppressors to be directly threaded onto 1/2x28 barrels. Designed and manufactured by Diligent Defense Co, this adapter provides a secure, reliable, and low-profile connection between your 1/2x28 threaded firearm and any suppressor featuring the popular HUB (1.375x24) mounting system. This eliminates the need for a separate muzzle brake or QD mount, offering a simple and effective direct thread solution for AR-15s, pistols, and other 1/2x28 threaded firearms.

Performance and Handling
The Diligent Defense Co HUB DTA 1/2x28 Direct Thread Adapter DTA12 delivers reliable performance by providing a stable and repeatable mounting platform for HUB suppressors. The direct thread design ensures the suppressor sits securely against the shoulder of the barrel, promoting excellent alignment and reducing the chance of baffle strikes. This results in consistent accuracy and minimal point-of-impact shift when mounting and removing the suppressor.
Because it uses a direct thread interface rather than a quick-detach system, the DTA12 helps keep overall length and weight to a minimum — an important consideration for pistol builds and compact rifles. The adapter is machined from high-quality steel and finished for corrosion resistance, ensuring long-term durability even with frequent use. Shooters appreciate the simplicity and reliability of this mounting solution, especially when switching between multiple HUB-compatible suppressors. Whether used for home defense, competition, or recreational suppressed shooting, the Diligent Defense Co HUB DTA offers a clean, effective, and professional-grade mounting option.
