Good only for scope without kill flash - ScopeCoat Elcan DR Specter Thermal Rifle Scope Cover

The cover is short, only covers scope without kill flash. I think if you use a SpecterOS 4x, or the SpecterDR 1-4x without kill flash, it will fit well. With kill flash on, this cover is too short, cannot stretch to cover the scope anymore. At the same time, I also bought the bikini caps, the caps are made the same way, only covers the scope without kill flash. If your scope has kill flash on, you need measure the size of the scope, find out a cover fits it.
