Holosun 507K X2 Product description

About the Holosun 507K X2

Holosun 507K X2 is a red dot sight from the Reflex series.

The letter 'K' indicates the red dot sight's unique, miniature shape which makes it ideal for pistol use. It has a modification of the Shield RMS footprint instead of the Trijicon RMR footprint found on 407C, 507C, and 508T.

There are two large buttons for illumination control on the side of the Holosun moa red dot.

The 507K reflex red dot features the Holosun ShakeAwake function. When left powered on, the device will go from 'active mode' to 'sleep mode' after a while to prevent unnecessary battery drain. Once moved, it will power back on immediately.

Holosun 507K X2 red dot is the second generation from the 507K series of red dot sights. Not many differences can be found between the first and second generations.

Holosun added the button models lock mode and made the illumination control buttons smaller. The buttons on the Holosun ‘X2’ reflex optical sight are also placed horizontally, whereas they were placed vertically on the first dot sight model.

About the Holosun Reflex series

Reflex is one of the red dot sight series made by Holosun. These compact sights are not closed on both sides like the Holosun Tube, Holosun Infiniti and Holosun Paralow series, which is why they are very compact and lightweight (there are some exceptions to this in the Holosun Reflex series – 512T is closed from both sides and thus bigger while 510C is a reflex-type red dot sight of a bigger design).

Holosun 407K dot sight and Holosun 507K dot sight are designed specifically for pistol use – these red dot sights are even more compact than Holosun 407C, Holosun 507C, and Holosun 508T models. Holosun 407K red dot sight and Holosun 507K red dot sight are the first Holosun red dot sights that are equipped with a central dot size of 6 MOA.

The illumination is powered by a CR1632 battery. The click value for the elevation and windage adjustments is 0.5 MOA. These durable red dot sights feature a single-piece housing made out of 7075-T aluminum. Altogether, there are 12 illumination intensity levels to choose from, 2 of which are NVD compatible. The battery life is 50.000 hours.

About the Holosun "507K" family

Holosun 507k dot sight is one of the model families in the Reflex series. The first number '5' in its name means that the user can switch between a 2 MOA dot; a 2 MOA dot surrounded by a 32 MOA circle or a 32 MOA ring only.

Mounting details of 507K red dot sight

Holosun 507K dot sight has a modification of the Shield RMS footprint for mounting purposes. Ifyou are interested in footprints on red dot sights, read our article Footprints/Mounting Standards on Red Dot Sights

All Perfect, but the screws...

Wonderful little thing as accurate as its big brother ( HS 507 C ) but tinyer ! Mounted on my Glock 35 MOS Gen4, it makes its job perfectly... Just one (big) problem: i used Blue Loctite but the Holosun torx tool chewed the provided screws. Don't lock it and don't overscrew the torx or you will have to use a Dremel driller, like i did, to get your Red Dot back !!! One mistake from optics-trade review: You DON'T have to modify your Glock MOS mounting plate if you use a SHIELD Low-Profile for Glock MOS: it fits perfectly... No modification at all Knowing all this, will buy it again from optics-trade.eu for the ultra-fast shipping to France and the very low price.

Absolutely Superb Quality, Function and Sevice

Bought this Holoson HS 507K for my Sig 365 XL and it is a marraige made in Heaven. Simple to install and side access to the battery is smart. Illumination and sighting adjustments are clear and clean. Picking up the sight picture is smooth and quick. Love, love, love this upgrade to an already amazing gun. Optics-trade provided fast and coirteous service. They were exceptionally responsive to my communications and always leaning forward to be most helpful. I will definately buy for them again.

TBD

Reasonably price considering the scarcity of this optic. And it shipped reasonably quickly. However I am very disappointed that it did not ship with a battery.

Need to find a baseplate for my stoger str9c. Please guide me to this

by Forest

Dear Sir/Madam,

thank you for contacting us.

In case you have an optic-ready model, then the manufacturer provides you with 4 different adapter plates.

In case the model is not optic-ready please contact your local gunsmith who should be able to custom-make or find you the correct dovetail adapter plate for your pistol.

Unfortunately, we don't have any adapter plates for this pistol in our offering.

Thank you for your understanding.

Kind regards.

I am getting my Shield Plus Performance Center milled. I am buying the 507k GR X2 does this have the same exact footprint as the original 507k.

by Nicholas

Dear Sir,

thank you for contacting us.

The 507k GR X2 and 507K shares the same footprint.

You can find more information regarding mounting standards on red dots here:

https://optics-info.com/footprints-on-red-dot-sights/

Kind regards

by Optics Trade team

Hello, does the HS507K X2 fit also to HK SFP9 OR gun or do i need to purchase some special mounting plate? If so do you sell it as well?

by Jan

Dear Sir,

thank you for your inquiry.

The Holosun 507K X2 features a modification of the Shield mounting standard.

If your pistol is optic ready for Leupold DeltaPoint Pro which uses the Shield mounting standard then it is possible to modify the adapter plate to fit on the pistol. The rear lugs have to be removed and the front ones have to be shortened in height - this is best done by a gunsmith.

We hope this was helpful.

Should you require any further assistance, you can contact us anytime at info@optics-trade.eu

Looking forward to hearing from you.

Kind regards

by Optics Trade team

Hello I have a holosun mount for 508T, is it possible to mount 507k x2? I see that a modification is possible? Regards

by Romuald

Dear Sir,

thank you for contacting us.

You can take a look at the desired mount on the page below.

https://www.optics-trade.eu/en/shield-sights-sms-rms-mount-plate-for-trijicon-rmr.html

However, please note that you will need to modify this mount in order to fit a Holosun 507K X2.

Should you require any further assistance, please do not hesitate to contact us again at info@optics-trade.eu

Kind Regards,

I own Canik Mete SFX which has an RMRcc footprint to directly mount optic to slide without any mounting plate. Will the Holosun HS507K X2 that has an RMSc footprint mount on this RMRcc footprint cutout?

by Timothy

Dear Sir,

thank you for contacting us.

Please note Holosun HS507K has a Shield RMS/SMS footprint standard. Also, it features a modification of the Shield footprint. The differences are:

the two rear sockets are missing
the sockets in the front are shallower

Meaning any Shield RMS/SMS mounting plate will need to be modified in order to be compatible with the reflex sight.

Thank you for your understanding.

If you will need any additional information please do not hesitate to contact us again.

Kind Regards

Do you have plates for Holosun 507k that would help to mount this red dot to Glock 43X?

by Paul

For the conventional non-Optics-Ready model of Glock 43X, you will need to take a look at the desired product on the page below.

https://www.optics-trade.eu/en/shield-sights-sms-rms-low-profile-slide-mount-for-glock-43.html

If you have the Optics Ready model we would advise contacting the Glock manufacturer directly to supply you with the suitable adapter plate. Please note that Holosun 507K X2 shares the footprint of Shield Sights.

by Optics Trade team

will Holosun 507K X2 work on a Beretta APX?

by Ganon

We would kindly ask you to specify if your Beretta APX is an Optics Ready or a regular model. If you have an Optics Ready model you must make sure that you have the Shield Sights adapter included with the package, since Holosun 507K X2 is actually a modification of the Shield Sights footprint.

The differences are:

the two rear sockets are missing
the sockets in the front are shallower

Namely, the two rear indexing lugs on the pistol have to be removed and the two front indexing lugs shortened in height. Hellcat and Walther PPS are examples of such pistols (some pistols, such as Sig Sauer P365XL, do not have to be modified).

If you have a classic model that is not Optics Ready we would kindly ask you to contact us directly at info@optics-trade.eu for further assistance in this matter.

by Optics Trade team

Dear sirs,

I had seen a video on TFB TV with James Reeve interviewing Luis of HOLOSUN talking about the full line of HOLOSUN Red Dots. They talked about the new HS507K x2 reflex sight and it seemed to me they inferred it would work on a AR 9mm pistol. I’ve purchased one for a CMMG Banshee but seem to not find a high rise picatinny mount and don’t find one on the HOLOSUN web site. Are there any high rise picatinny mounts that or MOS plates that can be used? I really would appreciate some help & advice.

Thank you for your time,

by Gary

The 507K X2 model is not as straightforward as with the majority of Holosun red dots. 507K has a modification of the Shield Sights footprint, which is why it is going to be extremely difficult to procure a riser for it. We actually do have a mount that works as a riser, however, it requires some modifications.

https://www.optics-trade.eu/en/shield-sights-mount-for-picatinny-rail-78915.html

This mount is suitable for 507K red dot sight, however since Holosun uses a modification of the Shield Standard as we described previously, you will need to remove the two rear indexing lugs on the mount and shorten the two front indexing lugs in height.

by Optics Trade team

Hi, I wand to install on my Glock 19 (no MOS) your Holosun 507 k, do you have adaptor ?

by CANILLAS

You can take a look at the suitable mount on the page below.

https://www.optics-trade.eu/en/toni-system-pistol-mount-for-glock-17-19-22-23-34-35.html

You should choose type A in the "size" chart.

by Optics Trade team

Is there an adapter for this optic to mount on top of a scope?

by Flynn

We would kindly ask you to specify as to exactly which scope would you like to mount this red dot sight to?

by Optics Trade team

why is your Holosun 507K's shipping cost does not have express mail option?

by Yingnan

We would kindly ask you to specify to which country would you like this Holosun to be shipped.

by Optics Trade team

Hi, is there any chance that you get your hands on the Holosun HS507C-X2 with the ACSS® Vulcan reticle? If so I am buying one. Thanks and regards.

by Marcin

Unfortunately, the ACSS Vulcan reticle is not yet available for purchase. Please stay tuned on our Holosun product page.

by Optics Trade team

I notice this comes with 2 sets of screws. What sizes are they?

by Leigh

There are 2 sets of screws included (4 screws) with different threads. Unfortunately, the thread sizes are not specified. Holosun recommends using either the included screws or screws supplied with your handgun slide.
