- Precise Fitment: Various versions are available for a multitude of scope objective end diameters and scope cover sizes.

- Reduces Glare: The killflash reduces glare / reflections from the glass on the objective end of scopes. One side of the killflash will have some shine due to the print bed, ensure this side faces inward and the matte side faces forward outside the scope.

- Securely Held To Scope: Cover is held onto scope by being sandwiched between the scope and scope cover. Ensure your scope cover has an inner lip which can hold the killflash against the end of the scope. SCOPE COVER NOT INCLUDED.

- More Versions Available Upon Request: If you need a version I don't offer, such as for a different type of scope cap, please email me at

- Original Design: 1500+ products designed and 3D printed in the heart of America in St Louis, Missouri by Hammy3DPrints.

NOTE: If there is any stringing between the hexes, these can be easily removed by taking a lighter and very briefly (less than a second) passing the flame over the strings.

Disclaimer: I am not associated with any Butler Creek or any scope manufacturer. The killflashes are made solely by Hammy3DPrints.
