Holosun 507C X2 vs 508T X2 - What's the Difference?

These two optics seem very similar, so what is the difference?
I left price out of it but the 508 is more expensive and that is due to the materials.

Good straight forward review! Do both sights come with a picatinny adapter? Also, which do you think would be better for use on a shotgun for target shooting to a maximum range of 50 yards? I'm also considering the Vortex Venom.

Unfortunately, neither of them come with a pic adapter. You would need to get a pic adapter for RMR footprint. Honestly, either option would fit great but I personally would go with the 508. I’ve really been enjoying that guy, it’s making me not like the curved top of the 507 so much.

@@DigitalArmory_ Yeah, I would think that the curved top decreases the total viewing area.

I agree.
