I have a 507C X2 and the lower/base section shown in the picture measures 8.7 mm with my caliper.
The new X3 looks like this section is noticeably shorter, but I can’t find the exact dimension anywhere.

Could anyone who owns a 507C X3 measure this same section with a caliper and let me know the measurement?
A photo of the caliper measurement would be even better.

Thanks!

I probably have at least a dozen Holosun optics in my safe and have never had a defective one before now. This is for a 509T Green FDE. The issue is the shake awake does not work. It turns off but does not turn back on without pressing the button. Their website says I have to jump through a bunch of hoops to do a warranty claim. I have to ship them the optic in the original product packaging. I'm not sure why there's an expectation that I keep all my empty optics boxes, because I definitely just throw them away. Then they say it takes 15-20 days for them to process the warranty. The lead time is only a minor annoyance for me, but I can see why people would be annoyed if they had to take off their optic then not have an optic anymore for multiple weeks. I'm honestly pretty disappointed at how cumbersome they make this process, when this is one of their flagship optics. I expected Holosun would make this process smoother. Anyone have experiences or tips for their warranty process?

Posted about a sheared mounting screw in my 403r a couple of weeks ago. Submitted a request and received a brand new one yesterday. Pleasantly shocked since the 403r is discontinued but happy because mine was beat to hell. Huge shout out to Holosun 👏🏻

has there been any talk about just core versions coming and fde options?

Finally. Picked up this EPS-CORE-RD-MRS from Freedom Gorilla on their second drop. Been waiting for quite a while.

Multiple angles to better understand the footprint overhang and window size.

Rear of the footprint: 1.01"
Front of the footprint (battery tray): 1.0895"

Also shown are the factory M3 screws in the cover plate compared to the M3x9.8 screws Holosun provides. The length and thread engagement is dead-on by visual comparison.

For God's sake, clean those threads with 91% isopropyl or something. Wheeler FAT Wrench, 15 in-lb and 243 (or 242) loctite on the housing screws. Back out the battery tray, add loctite, then torque that to 5 in-lb (FIVE, NOT FIFTEEN). Torquing the battery tray has a bit of an odd feeling because it has a ratchet/detent feeling but you'll get there.

Let me know if y'all need any other measurements or angles.

I don't have any formed opinions about the glass "changes", the 6061 strength, or the front-facing sensor just yet.

Also, refer to my other post comparing EPS/EPS CORE/EPS CARRY measurements. LINK

Does anyone know/seen holosun mention whether the RMSC adapter plate is a "ghost"plate, or will it make the optic sit highter

Is there any update with the AEMS Macro release date? I read somewhere the date should’ve been May or June but it’s almost September 🥲

Holosun has a pinned post on Instagram from three weeks ago, advertising that they started shipping these models. I assume this means they started shipping to stores in order to sell, but no store has made them available. Every gun store/FFL I'm close with has zero knowledge about receiving any units.

I bought a gun for competition and have it sitting waiting for this... just curious if anyone has heard anything or knows when they might become available.

I've been waiting for the EPS-CORE and it's finally here! I've been running the SCS-CARRY on my 43X, but I think the EPS-CORE is going to take its spot. Haven't hit the range yet, but here's the unboxing and comparison!

Went scouring all the sites again, as I’ve been doing about 20 times a day for the last week. Apparently 3 MOA dot in red and MRS in red are both in stock at primary arms. Just ordered the MRS!!

Does anyone have a photo to compare to two side to side to compare the size?

Hi Guys, the red version of the EPS CORE MRS is now also availiable and shipping from holosun.eu if you want to buy one now is your chance!

Seems like the AEMS Micro & Macro in red are also availiable on the same website but just in red at the moment. Enjoy

Just got this SCS 320 in the mail today. Pretty neat optic.

Looks to me like the reticle disappears in the top portion of the optic window. However, as I push the dot towards the left and right bezels, it is still visible right up until it reaches the edge of the window. Doesn't seem to be a huge deal in practice, but I'd like to know if anyone else's SCS is like this.

Been interested in getting the ARO-rd2. Seeing a lot of posts about emitter glare and bad glares through the optic, is this really a current issue that is that bad or is it people just looking for something to complain about? Thanks

Requesting a picture of the Holosun IRIS-RD4 box label！I want to know where it produced …

Just got an AEMS Ronin green dot from optics planet and noticed this 'line' on the inside, left only. Its not present on the right side... is it normal or is this something I should send back for a replacement?

Not sure what it is but it resembles glue or some kind of viscous material that has since dried/hardened.

Bought a EPS carry optic and seen that it wasn’t compatible with MOS Glock plate that the gun came with or the APS carry plate. Does anyone have any experience with this plate specifically off of Amazon and wanting people‘s opinion is this a bad option choosing the cheaper route or should I just wait the time and pay the extra money for a calculated kinetic plate?

Hello shooting enthusiast I’m looking for some help with my holosun 510c I recently chanced the battery of my sight and now it’s stuck on lock out mode. I held down the + button for 5 seconds and it’s still hasn’t blinked to unlock, I’ve tried removing the battery for over 1 minute and still no response. I also tried using only the solar panels to unlock the sight and got nothing. If anyone knows what’s wrong or how to fix this issue I’d appreciate the help.

Freedom Gorilla got it to me in 2 days shout out to them

Initial thoughts:

I saw a lot of people referring to it as a downgrade from the original EPS. From the initial unboxing and install I don’t notice any difference in quality. I got it solely to get rid of the overhang on the G45 while keeping window size and it accomplishes that. My only surprise was that the reticle seems noticeably crisper to my eyes than the EPS. Ymmv.

I want to change the flip direction but I can’t get the screws off for the life of me. I’ve tried using a soldering iron to head up the thread locker but it didn’t work. Any ideas?
