Butler Creek Flip-Open Lens Cap, Lens

Butler Creek “Flip-Open” lens covers have been a favorite among shooters for a very long time. Butler Creek lens covers feature a “Quiet Open” function that allows the covers to open quickly and silently.

Measuring instructions: Measure the outer diameter of the scope with a caliper, or as accurately as possible using a ruler, for example. The lens covers stretch slightly (approx. 0.5 mm), so choose the correct size as precisely as possible. If you’re unsure between two sizes, go with the larger one. You can always make a larger cover smaller by placing a piece of electrical tape on the inside of the cover, for example.
