This fits the rear lens (side your eye looks through) of a primary arms 4-14x acss ffp. Fit well on my nikon prostaff 3-9x40 riflescope. It fits the eyepiece of nikon p-223 1.

The ones i received have a very satisfying click when they close and are very secure. The plastic construction feels solid, as does the flip up lever. It flips up and stays put.

Leopold alumina scope covers are a nice addition to any scope. The functionality of it is on point.

It fits perfectly. It's worth measuring twice and ordering once to avoid having to re-order the next smaller or larger size.

Great fit. As pictured. Good price. Super cool design. Good quality. Nice tight fit. The 43. Is super tight.

Followed fitment guidelines per service representive, does not fit scope. Spend the extra money and purchase another scope covers such as weaver. There's competition now, and the competition is better.

Ordered two of these (shipped 25 and 27 september 2020, respectively) tried to return on 13 october 2020, well within 30 days. Very disappointing. Save yourself the trouble and buy it locally.
