Now your choices are limitless! Get the full fun factor out of your ATI GSG Firefly Pistol in 22LR by mounting any 1/2-28 TPI end-of-barrel accessory such as a muzzle brake, flash suppressor, compensator, sound suppressor or any other legal thing you like.
The ATI GSG Firefly Pistol in 22LR Barrel Thread Converter (also known as a muzzle nut muzzle coupler or muzzle coupling) from Tacticool22 allows you to mount standard end-of-barrel accessories such as flash hiders, recoil compensators, or unrestricted FAKE Tactical Suppressors.
This threaded adapter is a direct replacement for the factory thread Protector.
For a consistent, clean look, the largest diameter matches current A2 Birdcage and similar flash suppressors. In addition, our AM1 Muzzle Brake looks great on this converter.
Barrel Thread Adapter Features
- M9 x .75 to 1/2-28 threads
- 3/4″ / 19mm wrench flats, so you can still easily field strip your rifle.
- Black oxide finish for years of trouble-free service.
