Thread: Review of the Holosun HS503GU Circle Dot (Black)

Quick update.
100 rounds in the rain yesterday and another 100 this afternoon in the sun.
No issues at all. No fogging or zero shift.
The 12g shotgun is a great performer at the shorter ranges (0 - 100 meters) with the right ammo.
I can see why the USA cops have one in every patrol car.

Looking forward to grabbing another sight when they come back in stock. I will run one on one of my AR's, probably a 223 to start with. I have a 3 x magnifier so will be able to give it a crack at longer ranges as well.
The magnifiers show up the dot quality so it will be interesting to see how crisp the dot.

I spent some time today patterning some different loads (Reloads and bulk shop bought target stuff)..
Well worth doing if you have never done it.
My No 4 shot reloads had large holes in the pattern. Once my stocks of components have gone I will likely go to of the shelf bulk ammo.
There is only about a $15-20 difference in cost per slab so its just not worth it at the moment.
