There can be some difference between scopes so we have 2 models: the Hyperion (long version) or the Hyperion 2.
For instance in the longer version the Nightforce AtacR 7-35 fits, but the Nightforce AtacR 5-25 is just too short. Therefor we designed the Hyperion 2. The S&B PM2, Vortex Razor HD, Kahles K624I also fit perfectly in the Hyperion 2.
If you're not sure which Hyperion you need, just shoot us an e-mail and we will set you up!
