*does not hold zero with .556* - Kinetic Development Group SIDELOK Universal Scope Riser

I was extremely excited about this product, paying a heavy premium I would expect the thing to do the one thing that it’s supposed to do. I was driving myself crazy at the range today, bore sighting shooting a few rounds to not be able to hit anything checking bore sight again and it being WAY off. I notice setting it up in a vice I can see movement just by pushing the scope with my hand. Super disappointing. Have no idea why there are so many positive reviews, either they put it on guns that stay indoors and don’t get used or I got a bad batch. The idea and design is very cool, if it worked it would be awesome but I can’t have it on my gun just to look pretty, it needs to be able to hold zero.
