Fletcher Rifle Works ST-TI-TA Titanium 1/2x28 HUB Direct Thread Adapter

The Fletcher Rifle Works ST-TI-TA is a precision-machined titanium direct thread adapter built to mount any HUB-compatible (1.375x24) suppressor straight onto a barrel threaded in 1/2x28. Designed for AR-pattern rifles in .223 Remington, 5.56 NATO, .300 Blackout, and other calibers using the standard 1/2x28 muzzle thread, the ST-TI-TA provides a clean, low-profile mount that adds as little length to the host system as possible.

The adapter threads directly onto the muzzle by hand and accepts any suppressor or muzzle device machined to the industry-standard 1.375x24 HUB (Harmonix Universal Barrel) pattern. There is no quick-detach mechanism to add weight, snag points, or tolerance stack-up - just a solid, repeatable lockup that indexes the suppressor consistently shot after shot.

Constructed from titanium to keep carry weight down, the ST-TI-TA is a natural match for lightweight AR-15 builds, competition rifles, and any host where balance matters. Fletcher Rifle Works machines its suppressor accessories in-house to tight tolerances so the threads seat cleanly and the suppressor runs true on every installation.
