Any thoughts on the Holosun 508 and 509? Both appear to be newer, yea? One is a closed design. I’m coming from a gen 1 RMR. Considering something new that needs to be duty read on a g45 mos.
I’m cross shopping DPP, Holosun and RMR 2.
The holosun uses a different emitter than the RMR, which for many results in a crisper dot, myself included. I have astigmatism and most dots are blurry to my eye, but the Holosun is crisp. I use a v1 407 and it's one of my favorite optics, I don't really see a need for the titanium housing at this point.
I have a 509T on pre-order with Holosun, but who knows when I'll see it. Nice thing is it comes with an RMR footprint adapter so no additional slide work is needed.
For the ones you have listed I would go Holosun > DPP > RMR. ACRO is my favorite, but also one of the most expensive.
