Holosun 503: Why it should be your first red dot.
2 years ago
24
This is my review on the Holosun 503 Series which includes the 503, and the 503CU the latter having a solar feature. This is Holosun's budget offering with the MRS, the 403 only has a 2 moa dot. The circle dot helps with my astigmatism and I get a clear picture allowing me to engage targets at distance. If you are just getting into guns or red dots I think this should be your first rifle optic as it has everything you would want, is very reasonably priced, and still sturdy enough.
