BR, guest, from TX, United States, asked on November 02, 2022

Does this cover fit on the Vortex Strike Eagle 1-8x24 Ocular lens? Per Vortex, the part number I need is C-03440-0. Is that this part?

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on November 04, 2022

This Vortex Sparc II Flip Cap will not fit the Vortex Strike Eagle 1-8x24. The Vortex Defender Flip-Cap model O-24 will work with that scope.
