will this mount to a g23 glock accessory rail?
jim shawny on Oct 25, 2018
BEST ANSWER: Were you dropped on your head as a kid?
will this mount to a glock 23 accessory rail?
jim shawny on Oct 25, 2018
BEST ANSWER: Wow, Jim... You've asked this same question 4 times. Are you...ok???
Do you actually HAVE a Glock 23? The accessory is UNDER the barrel. The Holosun is a red dot SIGHT.
To use a red dot sight, you have to look through it.
So, how is that going to work?
Does it “shake awake” while riding in vehicle?
BBlack on Oct 27, 2018
BEST ANSWER: No, the sight has a built-in GPS to detect speeds over 10 mph (16.1 kph) and it disables the shake awake feature.
will this sight fit my PSA 16" M4 Nitride Freedom Rifle, Flat Dark Earth ?
Alan N on Oct 25, 2018
BEST ANSWER: Yea, no matter what color it is
can i mount this to my glock 23 accessory rail?
jim shawny on Oct 25, 2018
BEST ANSWER: Naw family. It’s a red dot optic not a laser.
Can it be manually turned on/off? Thanks.
Andy Tracey D on Oct 27, 2018
BEST ANSWER: Andy, use the internets and look at the manual on the Holosun site.
Yes, you can turn the sight on and off.
But with a 50,000 hour ON life PLUS shake to wake to greatly extend that, WHY, WHY, WHY would you want to turn it off?
How high above the bore of a flat top AR is the sight? I need to know to run some ballistic data. Thanks.
George M on Nov 2, 2018
BEST ANSWER: George, YOU have to run some ballistic data??? This sight, like most other decent quality red dot sight, is set up for 1/3 Co-witness for every flattop AR platform. The Holosun site, which you should be referencing, says "Central Height (in) 1.63"
Now, go crazy with your calculations...

will this mount onto the 40sw gen 4glock accessory rail?
jim shawny on Oct 25, 2018
BEST ANSWER: Probably will but why? It’s not a laser, it’s a red dot and pretty large for a glock if it was milled.
Is this as good or better than the romeo 5?
Chris M on Oct 29, 2018
BEST ANSWER: I think they are basically the same thing, and same great price. The romeo5 looks cooler though. I heard that holosun makes sigs red dots anyway...
Will this handle the recoil of a 12 gauge? Want to put it on my Shockwave.
Josh V on Nov 5, 2018
BEST ANSWER: The Holosun site says it will take up to 1,000 Gs of shock.
When you mount this on your Shockwave, please be sure to hold the Holosun close to your eye and take a video.
Will this fit any mount an aimpoint t2 fits? Do all holosun red dots fit any aimpoint micro mount?
Craig L on Nov 9, 2018
BEST ANSWER: This will fit the T2 mount. Most Holosun micro sights will. with the exception of the HS403A, due to the unique battery housing underneath the optic.
So this is a red dot and alarm clock
in one?
Reeper on Nov 10, 2018

This is my first rifle to look into scoping. Will this fit a Ruger PC Carbine?
Shampoo on Nov 9, 2018

It states "low mount", but I bought a Romeo 5 which sits too high on my CZ Scorpion; will this work?

Does it come with a battery?
Zared H on Feb 1, 2019
BEST ANSWER: Yes. It comes with everything you need to take it out of the box and go to the range.
What is the Max effective range in yards of course? Thanks!
Michael F on Jan 10, 2019
BEST ANSWER: Part of it depends on your eyesight. Also depends on the target size. I use the red dot for 100yrds and in on some of my 5.56 and 308's. I've used it on man sized targets out to 200yds, and you could probably go out farther, but it's not ideal at those ranges without a magnifier.

TheRog on Oct 27, 2018

Well built, affordable MRO
I put this 403 GL sight on my Ruger PCC. I find it to be an accurate and intuitive addition to my basic rifle set-up. It holds zero after being taken down, transported, and reassembled. That's more a feather in Ruger's hat, but I'm pleased just the same. I like it and am impressed so much that I got a 503 GU for my 590A1 shotgun. Best thing going for eyes that are past their prime.
