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.
Can you still use the stock sights on a Ruger PC9 with this mounted?

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.
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
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.
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.
Out of the box, is it lower 1/3? Yes or no.....
Bushman on Dec 2, 2018
BEST ANSWER: 1/3 lower than what ?
When mounted on a flat. Top it is lower than a spark but not by much
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: Battery Only. You need a prism to have the etched.
What battery does this use?
Mic J on Dec 2, 2018
BEST ANSWER: Nice optic. Love it. Comes with a battery. Worth every penny.
Would this be a good option for a 300 blackout shooting subs. At coyotes in lowlight conditions?
Jennings D on Dec 2, 2018
Can this optic be mounted using a different mount other than the supplied cantilever mount?
Sandy S on Dec 8, 2018
Extra high recoil rating? Please specify.
cjcastellano on Dec 2, 2018

Solid Red Dot
Now I have several different red dots varying in price and quality, this one is a very good sight, it has been accurate and has not had any issues. It does take patience to turn on and it is heavier than some, but it is durable and easy to get batteries for.

Great scope for the money
Excellent scope with good accuracy on the range. It is easy to sight in and the red dot is easy to see and get on target.

For the price, it's really quite decent.
The laser is not overly well collimated and the dot is not a dot, but something that looks more like a tiny outline of the state of Georgia with Atlanta and Savanna shown as dots, when you get into the eye box it is good enough for most close in work. At $179 it's good enough, and if you really want better prepare to spend 2-4x more. I dropped the rear lower pin, sighted down the barrel, matched the dot to the barrel, and the fine adjusted from there.
