Faxon Stainless Steel Direct Thread to Hub Adapter | 1/2x28

Faxon Firearms^® Stainless Steel Direct Thread to Hub Adapter | 1/2×28

Universal Suppressor Hub Adapter for AR-15 Platforms

The Faxon Firearms^® Stainless Steel Direct Thread to Hub Adapter allows shooters to connect any standard 1.375×24 TPI “HUB”-compatible suppressor to barrels threaded 1/2×28. Engineered for precision alignment and long-term durability, this adapter is ideal for .223 Wylde, .223 Remington, and 5.56 NATO AR-15 builds where reliable suppressor fit and secure thread engagement are critical.

Precision-Machined for Suppressor Alignment

Each Faxon adapter is CNC-machined from stainless steel to maintain precise concentricity between barrel threads and suppressor bores. The result is a solid, repeatable mounting surface that prevents carbon lock and ensures consistent point-of-impact retention, even under high round counts or rapid heat cycles.

Durable QPQ Nitride Finish

The QPQ nitride treatment provides superior corrosion resistance, smooth threading, and a dark matte finish that matches most AR-15 components. This hard, heat-resistant finish extends service life while reducing maintenance and fouling buildup at the thread junction.
