I've always been a bit of an optics snob, sticking with the tried and true (and pricey) likes of Aimpoint, EOTech, and Trijicon when it comes to red dots. That being said, I've been more and more impressed by Holosun's optics, and jumped at the chance to review their 507c when Optics Planet offered to send it over.
Here are some of it's key features according to Optics Planet:
To be completely honest, I've had fairly limited experience with the multitude of miniature red dot sight (MRDS) offerings. I've looked down the Sig Romeo series, didn't feel too durable to me. The Vortex seemed decent enough for the money, especially given it's lifetime warranty. For my money though, the only MRDS that I've felt was trust-your-life-to-it durable (other than the new Aimpoint ACRO...review on that soon), has been the Trijicon RMR. It currently resides on my Gen 3 G19 on a Raven Concealment Balor RDS mount.
The 507c seems to be quite durable, and brags a battery life of up to 100,000 hours. The shake awake works great, definitely a neat feature. To do a mild test of durability, I mounted the 507c on my Remington 870 and set the optic to the 32 MOA circle with 2 MOA dot.
After some simulated drops, and about 500 rounds of buckshot, it was still humming right along so I decided to move it to my M17 that I had recently purchased an RMR adapter for. On the pistol, I found it a lot tougher to find the 2 MOA dot than on my Trijicon RMR with 3.25 MOA dot. The reticle seemed to begin to wash for me near the edges of the window, causing an almost odd glare across the glass. This was alleviated greatly when trying the 32 MOA circle with 2 MOA dot. I also felt that when presenting the pistol, the dot was more difficult to find on the Holosun than the Trijicon (also alleviated with the 32 MOA circle and the 2 MOA dot). While the windows look to be the exact same size between the RMR and the 507c, for some reason the RMR's feels bigger to me even after putting nearly 500 rounds through the M17 with the 507c mounted on top.
Overall, I'm pretty happy with the little Holosun, especially given the pricepoint of about half an RMR. I can definitely say I would recommend it for range use and light home defense use, especially with the 32 MOA circle with 2 MOA dot. The circle-dot reticle on the MRDS completely changed the game for me. I found myself shooting much more accurately wishing that other manufacturers like Trijicon would put a circle and dot type reticle in their MRDSs.
