Holosun HE507C-GR X2 Green Multi-Reticle Circle Dot Open Reflex Sight w/ Solar Failsafe and Shake Awake - HE507C-GR-X2

This is my 4th Holosun product. All have been wonderful with no issues. Great product with lots of features compared to others at a great price compared to what you get with other manufactures. Not to mention the great customer service and fast shipping from EuroOptic

I searched everywhere for this optic and at the time EO was the only website/storefront that had it.....Had never dealt with them B4 so I called spoke to Fletch? I think....very knowledgeable about this product...very matter of fact, I did the deal, they sent it RIGHT OUT....which is really nice with so many hiding behind CoVid excuses for SLLLLOWWWWWWW shipping when they are in fact drop shipping stuff they don't have....but say they do.... But I digress...... This green dot was for my CZ TSO and it is thus far everything I’d hoped it would be.....a GAME CHANGER for old eyes....mounted up perfectly with a single side frame mount..... I’m currently trying to determine if its staying zeroed.....The gun is BRAND NEW and I initially had some “issues” cycling AND since this optic is waterproof ( and about bulletproof) they only use 2 screws to mount to the plate instead of 4 like the Trij RMR..... ANNNDDDD.....one of my screws kinda stripped ....(too short) and the sight got loose ....but seemed to have gotten it fixed with a longer one......so I'm trying to determine if the inconsistency on my 2nd range zero day is optic, gun, or the shooter..... 1st 5 shot group from sandbags @ 15yds was 4” low 2” right.... I adjusted reticle got 3 in one hole @2:00 inside of a 1 1/4”Avery dot....1 a 1/4” 2:00 from that and 1 “flyer @ a 1/2” 1:00 just outside of the dot Moved 2clicks left and one down and shot 5 more...... ALL were 2” high and right from POA not touching......🤷‍♂️ That continued on for the rest of the session....so STILL trouble shooting ... But real world free standing, was able to keep rounds on Post it notes from 3- 10 yards with ease..... FWIW.....on my AR the sister unit 510c gr x2 off sand bags with 3x magnifier will keep 3-4 rounds in the bull @ 25 yds after zeroed....and holds zero very well after removal and reattachment using supplied Picatinny mounts.....

Works great and easy to install, fits Glock 43x perfectly

I mounted the 507c to a BUL Armory 9mm. The fit was tight and precise. While I haven’t shot it with the Holosun on yet, the sight is clear and the illumination sharp. The instant on feature works perfectly and the green is easy to pick up in all lighting conditions.

Great on my Crosman 1377 pellet pistol. Nice small size. Took a little reading to understand how everything worked. Thought I had power problems but found I had pushed the selector button and was not set where I thought I was. So pay attention to the instructions. I have stigmatism-so ordered the green version-and glad I did. Not perfect sight picture but much better than a plain red dot I have on my AR15 from a well known American major manufacture-and cheaper. Which it came with a cover though. For $300-you’d think an $8 cover would be included.

Holosun products have great quality, great features for the price. EuroOptic customer service and fast shipping is Top Notch.
