Sturdy red dot sight for the money - Holosun Paralow HS515BU Micro Red Dot Sight

Red dot looks good and strong for the money. Seems to hold zero pretty well after 500 round or so. Caps are very tight and well made as well providing a good seal for the lenses, they are a little tough to flip down at first. Glass clarity is pretty good. The biggest con I have for this sight and all Holosun tube style sights is the front glass. When the set the glass in the front at a cant they do not have timed edges on the glass nor do they fill the gaps left in any way. This makes it look unfinished and you can even see the glue on the exposed edges. Im not sure how the glass stays put so well sitting like this. Its not a huge issue with this style because the flash kill hides it fairly well. I have check multiple other brands around the same price point and this doesn't seem to be an issue with them. They shape the edges better or hide it with a retaining ring. The dot is also slightly distorted as well. I do not have a stigmatism.
