Compatible Flip Up Lens Covers And/or Bikini Covers?

Expert Answer
A
Answered by Mark H., Gear Expert, from IL, United States, on December 19, 2017

Unfortunately, there is not enough area on the optic for aftermarket flip-up covers.

If you have not yet purchased the optic, Sig Sauer's Romeo 5

comes with a bikini cover, as well as the Vortex SPARC AR.
