A review of holosun red dot optics has been published, covering models such as the 507c, 509t, and 507k. The review is part of a roundup of holosun optics, which are suitable for use on rifles, pistols, and shotguns. However, it is unclear if the review only focuses on these specific models or if it also includes other holosun products, such as the aems multi-reticle micro red dot sight.
