GoGun's Reflex Red Dot Sight is the perfect companion for your Huben GK1 or other Airgun. It's lightweight and durable, equipped with a 3MOA red dot sight for a comfortable sight-in and shooting experience. 

The design of this optic was chosen specifically to compliment the contours of the Huben GK1 Air Pistol. It is designed to fit on any Picatinny rail system, but the clamps can be removed and this sight can be paired with our Huben GK1 Sight Mount to provide a sleek and seamless look to your Huben GK1 with red-dot sight.
