Will this fit on a M-Lok Rail? What adapter would I need to buy?
Breanna on Jun 7, 2018
BEST ANSWER: Mlok refers to the slots on the rail that are usually on the sides and bottom of the rail. The top of the rail usually has a picitanny rail/slots. Optics should not be mounted on the rail though. (Unless it is a monolithic upper, somewhat rare). The top of the upper(non carry handle) will have picitanny rails and this optic will mount directly to the upper with the provided mount.
Is this a 1x unit?
Clint R on Nov 27, 2018
BEST ANSWER: Yes. There is no magnification
Vortex makes a 3X magnifier that has a swing away mount of you need it
It’s a slick set up
The heading says "4MOA Red/Green Dot", but nothing in the description mentions a green dot. Is it both???
AZCactus on Dec 8, 2018
BEST ANSWER: Yes. It it has a green or red dot. Just hold down the up button for a few seconds after starting up the scope and it will switch between red and green. It will stay on your last setting. I would not trust zero from red to green. They are very close in point of aim and point of impact but if you are competition shooting or doing anything longer range then zero on the color dot you will be using.
Would this be an absolute or lower 3rd co-witness on an AR with the A2 FSB?
Staeven on Jul 12, 2018
BEST ANSWER: The mount with that comes with it is a lower 1/3. Absolute co-witness mounts are available.
Out of the box, is it lower 1/3? Yes or no.....
Bushman on Dec 2, 2018
BEST ANSWER: Yes, lower 1/3
Hi I have a PSA AR, I believe this will fit on it with no problems. Are all mounts needed included? Your comments please Keith
Keith C on Dec 6, 2018
BEST ANSWER: Yes all mounts are included. The minute you get the package opened it can be on your rifle. I'll add in too that this is a fantastic optic, had mine for a year now and it's been great!
Is this parallax free like aimpoint?
Yukonstu on Dec 2, 2018
BEST ANSWER: Yes. To be honest for the money it's the best buy on an optic I've seen in years. Works well in any lighting and holds zero well. It does have a slightly larger dot than some other models but not really an issue.
will this fit on a colt AR?
badshot on Nov 26, 2018
BEST ANSWER: As long as your upper has rail on top and not a carry handle it will fit.
What battery does this use?
Mic J on Dec 2, 2018
BEST ANSWER: Nice optic. Love it. Comes with a battery. Worth every penny.
Does it only work as a red dot when under battery power? Or does the lens have etching for normal use?
golf k on Nov 26, 2018
BEST ANSWER: The StrikeFire II work with a projected dot. In short, no power, no dot. The glass is clear and not etched.
Would this red dot be able to withstand the shock from a 458 socom?
Marco M on Jan 7, 2019
BEST ANSWER: I'm using it on a .450 Bushmaster build and haven't had any issues, so probably yes.
Would this be a good option for a 300 blackout shooting subs. At coyotes in lowlight conditions?
Jennings D on Dec 2, 2018
BEST ANSWER: Yes and no as long as you are good with no magnification this is for more combat shooting
Extra high recoil rating? Please specify.
cjcastellano on Dec 2, 2018
BEST ANSWER: I’ve used on a 30-30 Henry. No issues.
Can this optic be mounted using a different mount other than the supplied cantilever mount?
Sandy S on Dec 8, 2018
I purchased this scope yesterday and typed in the code at checkout but it didn’t show that I got one?

Great optic
Optics works great personally prefer the green dot over the red. And as personal preference for looks, I’m looking to change out the mount.

A bit large for what it is.
I have nothing negative to say about the product except its size for being zero magnification i feel is a bit on the large side. Performs flawlessly under every condition ive had it in though.

I would definitely recommend this site.
I bought this site from PSA when they were running a sale, to try. It came with a cantilever mount and was easy to install. I put it on an AR that I had purchased from Wyoming Arms. First shot for rifle and site were right on the money. Excellent site for the $. The on/off/illumination buttons are difficult to manipulate, especially while wear shooting gloves. Turning site off is cumbersome. That’s the only reason I didn’t give it 5 stars.

Vortex make really good optics!
Really good dot optic. I also run Eotech EXPS and Trijicon MRO and this optic definitely belongs in the group. The light adjustment dial (brightness and color, red or green) is not the highest quality as the graduations are not pronounced and it is quite tight to turn. I run this on my carbine versus my ARPs as the added step of turning on the optic and dialing to the preferred brightness requires some extra steps before you can attain your sight picture and address the threat.

Palmetto State Armory is an awesome place to do business with.
Awesome red dot. Second one I’ve had. The first one I sold with the rifle it was on and regretted letting the red dot go.
So happy I’ve got another now.
