I mounted it on a Marlin 45-70 using the MI ghost ring setup and couldn't be happier!
This is a very nice unit that uses the same footprint as the Aimpoint T1, T2 etc. I mounted it on a Marlin 45-70 using the Midwest Industries ghost ring setup and couldn't be happier. Highly recommended!

Holosun always Delivers!
Great optic for the price. The green helps with my stigmatism and there is little to no starbursting at all. The ring around the dot also helps immensely with target acquisition. Highly Recommend!

Good green dot sight
This Holoson 503 is the green dot version with the 2 and 65 moa ring. I have red dot w only 2 moa dot an two of the Holosun with the second target circle. Really prefer the two target version. Great quality and easy to set up. Highly recommend.

Awesome budget green dot
Great little dot. The green is very easy to see and it's very crisp. I always had issues with red dots being blurry but these holosuns are great. I always get the green dot and never had any issues

Quality for Price
Easy to set up and use. Durable. Front lens is at a noticeable angle. That's normal for rifle red dots apparently. I didn't notice it on my pistol red dot. Just something to know if you're new to red dots.

Works great!
This site works great. It was a little hard to mount to my son’s Daisy red rider, but with enough epoxy, we got it on and centered ;-) and after that it was very easy to sign in.

No good
Unfortunately I am no longer a fan. There is what looks like a smear on the right side of the glass. I called Holosun and they state this is a known issue with the placement of the diode. Unfortunately depending on where the light is hitting you from it becomes unusable.
