Mr. Preachy is about to get preachy…
You don’t have a real clip on.
I’ve printed several sub MOA groups (with SH witnesses) with thermal clip ons. But they were real clip ons.
I’ve said a dozen times, and made goofy videos to prove the concepts, that commercial grade “zero the screen” clip ons aren’t in the same league as real clip ons… yes, my descriptions are lacking. Yes, my videos leave a lot to be desired. But damnit if I don’t keep seeing complaints about exactly what I warned about when people go the commercial “clip on” route
It’s totally fine to save money and get a pretend clip on (commercial clip on) (I own one myself). But expect constant issues from rail flex or RTZ mount issues as warned against constantly.
Unfortunately, even military clip ons (real clip ons) can have issues as witnessed with a few of the Theon units, so there’s no 100% perfect solution, but there’s definitely a way to bet and a way to save coin and they aren’t the same way.
This is NOT a “you’re poor” comment. It’s a “you didn’t budget enough for a clip on” comment. A $2500 used Super Hogster would have served you just fine. No big spending needed, even if you need to build an extra upper for it.
Clip ons, (real ones) cost a lot currently. If budget is priority, you can save a fortune by getting a dedicated thermal scope. For most use cases it’s actually a better device anyway. If you want to shoot small groups with a clip on (to a consistent POA), you need a real clip on.
Again, I own a fake clip on (and a real one) I get it… money matters… just don’t expect excellent results from mediocre budget.
