Holosun 507c on Scorpion Evo 3 S1?
« on: January 10, 2020, 03:22:08 AM »
Does anyone know the Holosun 507c co-witness with the CZ Stock iron sights? Also, do you think a Holosun 510c will be more fitting for a CZ scorpion?

I have both. The 510c functions well on my Scorpion pistol and carbine for Steel Challenge shoots. GET IT. The 507c window would be too small for my eyes on a Scorpion. But I just had one mounted on my SP-01... My 2 cents...

With the 510 you can’t use the factory irons.  They’re too low for that.  I like my 510.

If you don’t mind me asking, where did you get your holosun at? Really am thinking of picking one up.

I don't know if there is an optic out there that will co witness with the metal CZ sights. They are extremely low.

Yeah that’s true. I was hoping at least a lower 3rd co-witness. I hate that I can’t go to a store and just try one on my scorpion. The only resource I can go by is the Internet.

My Holosun HS503GU's co-witness perfectly with the Scorpion factory irons on my braced pistol with carbine forend and my braced Micro. The 2 moa dot works fine out to about 150-200 yds /65 moa outer ring works perfectly for rapid up close target engagements. Perfect for a 9mm carbine or braced or unbraced pistol. Put same on my F/A HK MP5 and it also co-witnesses perfectly.

Awesome! And by perfect co-witness, are you referring to a absolute co-witness? Or lower 1/3 co-witness?

Absolute co-witness. Using the shortest mounting plate that came with the HS503GU, my reddot sits on top of my front sight post.
I took a 2 day PCC/Subgun class last summer, 1200 rds, in the bright sun and in the rain, shooting at distance, moving, on an obstacle course and in 2 shoot houses. I never had an issue with the sight picture being "too busy" as I have seen claimed. I kept my focus on the threat/target and just superimposed the reddot onto the target and fired. Plenty of brightness adjustment for bright sun, selectable reticle between just the 2 moa dot or the 2moa dot with 65moa circle, programmable auto shut down with shake awake, something like 25,000-50,000 on the battery depending on which reticle you choose and the brightness used. Uses common CR2032 batteries. I've got 3 now and there will be at least 1 more for my 9mm Colt AR.

I bought my 510c a few years ago, right after they came out.  I can't remember which online retailer I bought it from, but Omaha Outdoors has them for $300 with free shipping right now.

Pistol with 507 and carbine with 510...
Does the 510 co-witness with the MBUS sights?
