It looks pretty decent with a 50,000 hour battery life, CR2032 battery,etc. Is Holosun on par with Primary Arms build quality wise?
yes holosun and primary arms are neck in neck with a tip of the cap to holosun due to the elevation and windage caps have a slit in them to aid in adjustment. i have no experience with the HE510-GR elite. I have run the micro red dots and had no issues with them.
