Moderator Adaptor DonnyFL Huben GK1

With this adaptor by DonnyFL, you can equip a moderator of your choosing onto the Huben GK1 air pistol. It’s made of impact-resistant 6061 T6 aluminium and it has a black, anodised coating that improves wear-resistance. As a result, the adaptor will look like new for a long time.

The DonnyFL Huben GK1 moderator adaptor consists of two separate parts. The adaptor itself and a thread protector with a knurled surface, that provides slightly more grip. Here’s how it works; there’s an end cap on the Huben GK1, that seals off the front end of the barrel shroud. By using an Allen key to remove that end cap, you can get to the threaded front end of the barrel and mount the adaptor onto it. After doing so, you can attach whichever moderator you’d like that has 1/2x20 thread or you can leave on the thread protector.
