Genuinely surprised - Osight SE 1x 21x14mm Reflex Red Dot Sight

I was excited to see just how good this sight was compared to the holosun 507c that I intended to replace it with. So it should be worth pointing out that the equivalent to the 507c is the OSlight C but I desired a smaller profile and a closed emitter model so I went with the SE. The clarity of the glass on the SE is much better than the 507c and there is zero fish bowl effect. In fact I didn't realize how distorted the 507c was until I started using this sight. Its super crisp. I've also shot several hundred rounds through and zero issues. Out of the box it was spot on so no adjustments were needed. I love it so much I bought a second one. Whatever Osight is doing they are doing it right. BTW I mounted it on a gen5 Glock 19.
