Holosun 509 with vulcan reticle - Primary Arms Holosun HE509-RD Enclosed Solar Powered Red Dot Reflex Sight

I thought I’d try this reticle on my pdp pro. Mounting plate for this combo is available on the secondary market you will NOT need to stack plates. The size of the lens is a tad small for me. Where other sites quote the diagonal directly, holosun doesn’t. Simple math gets you the number. The surounding structure is intrusive to my eye. Closest in my possession is a Romeo 2 in the enclosed configuration. Romeo 2’s window is brighter, a tad wider, and the site is not quite as thick.I like red in a site and green laser/ light, and have them set to overlap at 7 yards.The red circle dot I have in my Romeo 2 works better for me. Site adjustment for the holosun works well. I can’t speak to the battery/ solar panel contrivance claims. Will it fail if you hit it with a hammer, I couldn’t tell you. Warranties are not the same as Trijicon, Sig, Leupold, or Aimpoint. Cheaper than Aimpoint acro. Made in PRC?
