CTM 11mm CW to 14mm CCW thread adapter

CTM 11mm CW to 14mm CCW Thread Adapter

Unlock endless muzzle customization on your sidearm with the CTM 11mm CW to 14mm CCW Thread Adapter. Most factory GBB pistol barrels (including WE-Tech, WE Galaxy, Armorer Works, VFC, and G-Series builds) feature female 11mm internal barrel threads. This compact adapter seamlessly converts those female 11mm threads into standard 14mm Counter-Clockwise (CCW) male threads, giving you instant access to the entire world of 14mm airsoft tracer units, mock suppressors, and compensators.

Fully CNC-machined from single-piece steel and finished with a rust-proof QPQ anti-corrosion coating, this adapter is built to survive heavy field use. Equipped with dual rubber O-rings and 6mm of structural spacing, it keeps your muzzle devices locked dead-centre while preventing short-recoil outer barrel tilt from binding against your guide rod during rapid slide movement.

Key Features

• Universal 14mm CCW Adapter: Converts 11mm Clockwise (CW) internal female threads to 14mm Counter-Clockwise (CCW) male threads for standard airsoft accessories.


• CNC Steel Construction: Precision-milled from free-cutting steel to guarantee smooth, burr-free threads that won't strip or gall your outer barrel.


• QPQ Anti-Rust Coating: Treated with a durable QPQ black finish to prevent surface oxidation, scratches, and sweat/moisture corrosion.


• Integrated O-Ring Cushioning: Includes dual rubber O-rings to absorb thread vibration, prevent accessories from unscrewing, and maintain positive thread tension.


• Recoil Clearance Clearance: Engineered with a 6mm thread shoulder offset so mounted tracer units or suppressors won't interfere with tilting outer barrels or guide plug action.

BZ Tech Team Advice:

• Preventing Barrel Bind: On GBB pistols with tilting outer barrels (like Tokyo Marui or WE G-Series models), running a heavy full-size mock suppressor on an 11mm adapter can weigh down the outer barrel and cause slide cycling jams. For maximum reliability, pair this adapter with compact UV tracer units (like the Acetech Brighter C or Bifrost) or lightweight aluminium suppressors.


• O-Ring Adjustment: If your tracer unit sits slightly crooked or doesn't sit flush against the adapter shoulder, replace or lightly grease the included rubber O-rings. The O-ring compresses under hand-tightening to lock the device in place without needing force tools.


• Thread Safety: Thread the 11mm end into your pistol's outer barrel entirely by hand first. Never force-screw steel adapters with wrenches to avoid damaging softer aluminium factory barrel threads.
