I have several sets of these and have never had a failure yet. The set on my Ruger 30-06 have been on there for 20+ years and have never left me down. This thread reminds me I have 5 or 6 scopes laying in the gun cabinet that I need to get these for.
Callin all trucks this here's the Duck, we about to go hunting bear!
i have them on about 7 guns. I have had good luck with them. But.... two prolems that I have had pretty consistently with them. Objective lens covers with larger diameters (for 40mm lenses and above) are more prone to break, which makes sense since they have a lot more leverage on the hinge. The other problem is with the pin working its way out, popping off and losing the spring. I've cured that by getting little hex headed bolts the same diameter as the pins and sliding them thru and replacing the the pin. I then put the nut on with a little clear nail polish so the nut does not back off. The other thing I do is use black electricians tape to seal the part of the caps that slide on to the scope for additional waterproofing.
I have them on all my scopes. Have had some of the problems aforementioned. Now I use black electrical to tape all of them onto the scope so they stay put. I also disassemble the pins and put a dab of superglue, then reinsert it so it stays put too. Since doing that, I've had zero issues. If you use your rifle any amount at all with out these steps, you will have issues. I also recommend the see through objective lens cover instead of the solid one.
good info all. to the ones using the electric tape,are you using the proper size? I would think you should not need to put tape on it to make watertight.Did you contact the manufacturer and explain the problem? For the price of them Im gonna give em a trey.
I use them on all my scopes. Some have been on the same scopes for over 20 years. I have never had an issue with breakage or loose pins. I have had one or two that didn't fit as tight as I'd like, so a wrap of electrical take around the bell and they fit nice and snug.
the thrill is not in the kill, but in the experience
