These high-quality H-nubs have 2 available hardness and are comprised of aircraft silicone. They can be installed in four different directions, giving the user multiple configuration options. Because of the “H” shape of these nubs they increase the bucking’s contact with the BBs inside the barrel to improve both the range and accuracy of each shot. Additionally, they are compatible with Marui specifications as well as Hi-capa models, Steyr Scout models and more.
