Nice little optic here - UTG Pro 3.8in ITA Red/Green Circle Dot Sight w/Integral QD Mount

Got this for my kid's 15-22. Was pleasantly surprised when it arrived. Wow. for the price, this thing rocks. The circle dot is crisp and well centered. The unit feels like a quality build and of substantial weight. Well packaged, and easy to mount. My only concern is that the mounting bolt does not seem to extend far enough down into the rail channel to securely seat the scope to a depth that will hold zero under the stress of larger calibers. So far so good on the .22. I wish they would have added a riser. maybe just a .5 inch. It is too low to co witness with either the A 2 or typical height flip ups. In all, I'd get another.
