1/2-28 Barrel Thread Adapter for HK MP5 A5 .22LR

Now your choices are limitless! Get the full fun factor out of your MP5-A5 .22LR series tactical rifle by mounting any 1/2-28 TPI end-of-barrel accessory that’s available on the market.

This is the original MP5-A5 Barrel Thread Converter (also known as a muzzle coupler or muzzle coupling) from Tacticool22.

It allows you to mount standard end-of-barrel accessory such as a muzzle brake, flash suppressor, compensator, sound suppressor or any other legal thing you like.

This threaded adapter is a direct replacement for the factory flash suppressor. It even has the “O” ring groove. The converter has 3/4″ / 19mm wrench flats, so you can still easily field strip your firearm. You do not have to loosen the muzzle device to field strip your rifle, just the converter.

For a consistent, clean look, the largest diameter matches current A2 Birdcage and similar flash suppressors. In addition, our WM1 Muzzle Brake and AM1 Muzzle Brake look great on this converter.
