Question: What size batteries do I need for the Reflex and the laser ?
Document: So I keep going back and forth on this. I purchased in conjunction with the Sightmark 3x magnifier. I have other reflex sights and this one can hold it's own with the best as far as clarity and durability. I like the laser on it with the pressure plate. It can come off easily and I didn't have to re-sight it when I put it back on. The dot doesn't warp on mine with the magnifier like some others have reviewed.
I did not need a rail extension to see over the front site/gas post.Negatives:-It is far too easy for the attached laser site button to get pressed while in a case.-The included neoprene sleeve doesn't fit well.
I was thinking that I might need an expensive eotech sight until I used one of these on a AR 15. I was able to punch a hole out of a target and it  has not lost zero so far. I have just put less than 200 rounds with it on so far but I am very happy and its hard to beat the price. I have not used the laser much, but more rounds to come.
Picked this up a few months ago and got it sighted in. Holds zero just fine and works great from 25 out to 400 yards. The battery that was supplied still works fine but the one for the laser died after a few days cause the switch is lousy. Since I don't really care about the laser it doesn't really effect me. If you don't need the laser get the Ultra Shot Pro Spec NV QD instead and save a few bucks.
My honest opinion it works just fine with shotguns this sight was built for a .50 cal but I don't think it can handle that much power.Haven't tried the laser yet it does make a nice add on. Haven't messed with the night vision either cause you need other things to make night vision work. Overall this sight is very solid and built well, if you're looking for a halo sight that won't break the bank look into this product you will not be disappointed.
This is a good product for the money, and I would definitely purchase another if the need arose. Does not compete with higher end brands such as EOTech, which feature full-field holography and are therefor truly parallax free. This unit is parallax free only if the user is looking through the center two-thirds of the sight array, so not really a big deal. This particular model also features a side-mounted red-beam laser with both a toggle and a remote switch.
I purchased this sight - Sight Mark Ultra Dual Shot Pro Spec NV QD SM14003. The feel of the Optic is strong and stable. Feels heavy and well made. The quick release is solid and tight. The 4 reticles are as bright as they need to be and have 5 settings which include 2 NV setings for that use. The 4 types of reticles are awesome bright and clear. The laser on the side was exactly what I was looking for and one of the main reasons I purchased the Optic.
for the price, it is a fair deal. the laser has never worked and I tried 3 different sets of batteries. Other than that it is accurate and works good.
It took 3 months to get in the mail and then the laser didn't work, tried two sets of batteries, brand new and would not turn on. The holo sight seemed ok but I never mounted it or used it becuase it was junk. waste of money. Save the trouble of returning it and don't buy it
I received the item few moments ago. The reticle is clear and bright. Works great in low level light as well.system works well. However, the package included the batteries for the optic but not the laser. Packaging and description said batteries included. So be sure to pick up AG13 (LR44) batteries also.
Answer: yes
