What base do I need for a glock21?
Aaron O on Apr 15, 2019
BEST ANSWER: The HS507C has the same foot print as the Trijicon RMR. You will need a rear sight dovetail base for that model to fit your Glock
Does this sight also have a battery ? I’m assuming the battery would act as a backup , such as low light. Does power usage swap automatically ?
Bigfoot on Aug 28, 2019
BEST ANSWER: If there is enough light then the Solar powers the red dot. If not then it goes to the battery. The Solar does NOT recharge the battery. Still an awesome setup and will extend the battery life for YEARS.
Can you use it on a 300 blkout pistol?
Joseph B on May 30, 2019
BEST ANSWER: Yes. It will mount on anything with a pic rail. It will be very low to the top of the rail though and will possibly be less than desirable for target acquisition. It would work but there are better choices out there for less money. I’d look into the holosun he503c that has a built in raiser.

Bigwang on Jan 3, 2020

will it fit on a mount for the Fast Fire III & Vortex Venom?

Will it fit trijicon rmr pistol mount?

Will this fit on sig p320?
Andrew Y. on Jan 25, 2020
BEST ANSWER: Unless Sig has changed something it won't fit. I have the P320-M17 and I checked just to be sure, it won't fit as it comes from the factory. Maybe someone makes an adapter now, I haven't checked recently.
will this fit on a glock 19 gen 4 mos?
Walker M on Jan 18, 2020
BEST ANSWER: If you have the RMR adapter plate for your MOS then it will fit. Just remove your factory cover plate, install the RMR adapter plate and then install the optic.
GADSDENREBEL on Jan 10, 2020
BEST ANSWER: If you have a slide that is milled for a micro red dot like the Trijicon RMR or has a picatinny rail, it should work. I believe this has the same mounting pattern as the RMR.

RodneyC on Nov 15, 2019

Would this be a good option for your AKV ?
David B on Feb 6, 2020
BEST ANSWER: I don't have the AKV, but it would a good choice for any pistol or rifle where you'd want a smaller footprint. Optic is super crisp. It does come with a low mount which would be more ideal if it was to be put on the AKV IMHO.

sometime if you have to re-zero.

Easy to use with astigmatism
I tried the smaller dots, and found the larger moa circle with dot inside was easier for me to find and helped with the “starburst” I saw with smaller dots on other pistol optics. Works well in rain, so far.

Good Affordable RMR
Fits on my P80 project well. It was the only reputable optic within my budget at the time. It holds up to competition and daily carry wear.

Easier to see quickly
I like the large circle reticle for speed, easier to find when moving in competition.

Great Optic
I never thought I would like a red dot on a pistol until I built a new slide for one of my Glock pistols. This one changed my mind and so far is working fantastically

Replaced the rear (adjustable) sight on my Ruger 1911 Target 9 mm. Doing a fair amount of dry practice with it (really needed, as it takes some getting used to.) Have not yet fired it, waiting for the "stay home" to end. Looking forward to sighting it in and then taking it to a training course in about 6 weeks.

Good looking RDS
The 507 sits well on a G26. Reticle is easy to pick up, shake awake is very sensitive (good). I have high expectations for durability.
