Q: How do I know if these covers will fit my scope?
A: Measure the outer diameter (OD) of your objective and ocular bells, not the stated lens size (*). If it’s between 55 and 59 mm the objective fits, If etye is 44-49mm, these covers will fit.
* stated lens size. example: Your scope is 6-24x50 = 50mm diameter glass lens. This is NOT the outer diameter. That is bigger.
Q: Do they fit both rifle and spotting scopes?
A: They’re designed for rifle scopes, but will fit any optic with the correct OD measurement.
Q: Are they waterproof?
A: They are splash-resistant and keep water off the lens, but they’re not sealed caps for full submersion.
Q: Do they stay shut when moving through brush or in storage?
A: Yes—the snap fit is firm, keeping the covers closed until you flip them open.
Q: Can I leave them on permanently?
A: Yes—many shooters keep them fitted full time to protect the lenses between sessions.
