Pulsar Krypton adapter for scopes with 42 mm front lens. With its help, the adapter can be connected and removed from the scope extremely quickly. It is a novel idea that the adapter allows precise 3D adjustment and centering of the adapter from different sides with the help of an allen key with the help of a special mechanical part. The aluminum alloy housing provides sufficient stability even when shooting. The adapter is fixed on the scope's outer tube using a spacer ring. The right size ring should be chosen from the attached sizes. Spacer rings are compatible with the following scope front lens outer tube diameters: 45.5mm46mm46.5mm47mm48mm?49mm50.6mm
