Butler Creek 20130 Flip-Open Eyepiece Scope Cover 1.57"/39.90mm Size 13 Black Polymer

The Butler Creek 20130 Flip-Open Eyepiece Scope Cover is a custom-fit protective cap designed for the rear (eyepiece) end of your riflescope. Sized at Size 13 to fit scopes with a 1.57"/39.90mm eyepiece tube diameter, this cover slips on and locks into place, creating a watertight, airtight seal that keeps rain, dust, mud, and debris off your ocular lens in the field.

Built from durable black polymer, the spring-loaded flip-up cap stays firmly closed during transport and pops open with the touch of a finger when you're ready to shoot - no fumbling, no lost sight picture. The precision custom fit is engineered to prevent field-of-view blockage and to eliminate accidental opening, while the slim profile keeps the cap from snagging on gear or branches.

A staple for hunters, precision rifle competitors, and anyone who runs a scope hard in rough conditions, the Butler Creek 20130 is one of the simplest, most effective upgrades you can make to protect your optic's eyepiece. Slip-on installation requires no tools or modifications to your scope.
