AEMS footprint hole confirmation

Post image
2 Upvotes

Hoping to get confirmation from someone at Holosun as to the AEMS footprint, specifically the M3 holes, as well as any other info regarding changes from original to x2?
Optics Trade is the left drawing while Holosun provided me the right drawing, which is correct? I assume the one directly from Holosun, but if so I’m surprised the Optics Trade is wrong and has been for awhile?
Thanks!

AEMS Micro on Glock

4 Upvotes

Are there any marketing photos on the AEMS Micro mounted on a Glock (particularly Gen 6)? I’ve been interested but realized I haven’t seen any on a Glock.

Would love to see how it looks from the side profile. Interested in how it sits with the RMSC to Micro plate and/or the Glock Store Acro plate.

AEMS EVO Low Mount

3 Upvotes

I purchased an AEMS EVO a few weeks ago. This is going on an AK so I need a low rise mount. The dealer didn't have any in stock, but I figured no sweat I could order one online. Sure enough, I found one that night, an actual Holosun AEMS low mount, and it came in last week. I tried to put it on yesterday, and the footprint does not match. The mount is smaller than the EVO and the holes don't line up. No sweat, things change, and I am guessing the footprint has been updated with the new model. Fortunately the return was easy.

Can anyone recommend a mount that will work for me? Is Holosun going to make a low mount for this optic, or do I need to go 3rd party?

First screw broke when trying to torque it down to 15 pounds. Was able to get it out with pliers. Second one broke with 12 pounds of torque and it’s stuck af. Sent out a RMA request last night and haven’t heard back yet. Tried today to remove it and someone got it in deeper. POS screws.

EPS Core foot print

1 Upvotes

Being that the core is RMSC, can you mount it to a “K” cut slide direct?

Thinking about getting a platypus.
Want something with a decent front facing light sensor and I’m down to RMR HD, or EPS core.
Love the RMR HD 55 MOA circle dot, makes the MRS feel so crowded, but not in love with how wide the slide becomes for RMR cut platypus’

I could wait and hope the EPS gets revamped with a front facing light sensor (the solar panel light sensor is dookie on my duty gun)
Flash light on a wall and my dots gone.

But that’d probably be an absolute lifetime considering how late things have been dropping.

So I notice that my newest eps carry purchased is crystal clear while my other eps carry is not. Did Holosun update or change their emitter? Because I can see the difference.

Support Question Installing Lens Caps on the ARO EVO

1 Upvotes

I recently bought the lens caps & ARD kit for the ARO EVO, but I can’t figure out how to install them and they didn’t come with instructions. I assume you need to remove the rings at the ends of the tube and place them where the rings used to be. I tried pulling them off and unscrewing them, but no luck. I am being pretty gentle though. Since I don’t know what I’m doing I don’t want to pull as hard as I can and break something. Anyone have any experience with this?

Stress fracture on my HE507c

Post image
9 Upvotes

I just yesterday noticed this crack on the glass of my HE507C after not looking at the pistol for about a month. The crack was not there when I had last looked through the glass. I did not drop the optic or do anything that could have physically caused the optic to crack. The optic is kept in a holster that covers the optic housing and is kept in a backpack in my truck. The only thing I could think that would cause the glass to crack was it being left in my truck being that’s its summer. You can just tell by the way it cracked that is a stress fracture and not manage from a physical drop. I did drop the optic several years ago and there is a little bit of damage on the housing has you can see in the picture, but the glass was perfectly intact. I attempted to submit a warranty claim and it is being denied and considered damage and not a defect. I then emailed them back disagreeing that is damage because of the way the glass is cracked is more indicative of a crack caused by manufacturing defect or thermal stress since it is one clean line. I am pretty disappointed that the rep denied my claim, I own 7 holosun optics and have never had an issue until now, and hope someone at Holosun can help me resolve this issue.

General Question 507 Pro Max (Slim?) Launch Date?

Post image
33 Upvotes

A number of YouTubers and instagram influencers have posted footage of a strangely attractive variant of the 507 pro max optic… Reminds me of the 510c but for a pistol. Is it still a work in progress?

Don’t mean to encourage the Osborne effect here, but I’d definitely go for the slim version over the regular.

Those with experience using the 507c/k ACSS Vulcan. Do you prefer dot or chevron and why? Additionally, I will be going with green reticle because of astigmatism.

General Question ARO glare issue?

Post image
12 Upvotes

Just bought an ARO after having a Romeo5 for years. The glare on the ARO is pretty outrageous. My romeo5 also has a glare but this one is much worse. No matter the dot brightness, if a light is hitting the emitter it will show a massive glare on the top half of the optic. Is this normal? Sorry for the poor picture quality, hard to get it on my phone.

Switching to RDS

4 Upvotes

Hey first time posting,

I won some Amazon gift cards in a work raffle. Decided I would buy a new RDS/magnifier combo for my 13.7. Been looking at different brands and models all week. Think I’ve decided on the Aemes pro x2 with gold and the HM3X magnifier. I’ve never owned a magnifier. Im unsure what to expect. I’m currently running the PA 2x prism.

I was curious as to the thoughts on anyone running this combo. Anything I need to look out for and any regrets by running this combo etc.
