Question: does this take the cr2032 battery?
Document: Enough to take out a deer but not the fly on its ear.
The optic is great but the instructions referenced a tool to use that was supposed to be included which wasn't, had to take to a gunsmith, an added expense.
First impression, WOW. This thing comes in great packaging, warranty info, extra battery.Looks great on my gun, and fits WITHING A CENTIMETER over my flip up rear sigh, if you have magpul BUS then the throw lever will not sit totally flush against your receiver though.
another thing I noticed was that the rheostat knob contains the battery under a cap on top that just screws off and I can see this coming loose and dropping the battery out in the field. these things all seem minor when compared to the nearly $2000 price tag of an ACOG. if it falls apart, I'll update you
My Magpul rear flip-up rests perfectly under the eyepiece. It comes in a cardboard box with manual, warranty card, cleaning cloth, the battery is installed already, and a spare battery is also included. I have faith in this scope, and I would recommend to anyone looking for a combat style gun sight.
Got mine in the yesterday. Fit well to my dpms ar. Seems well made. Only four stars because I haven't been able to take it to the range yet. Will update if any problems.
That also means you don't have to have the power on all the time, which extends battery life. Batteries are CR2032, quite common. Only bad point is that it is not a variable magnification, although NCStar does make one with variable mag. The 4X mag limits the field of view too much under 100 yards. But if you don't need variable mag, you're doing good to get this sight.
The battery powered illumination is quite useless for me at least. I felt it is too bright even at lower sittings, but that's just me, others might find it useful.well that's all for this review. I recommend this scope for anyone on a budget, but still need a decent scope for target shooting and hunting or saving up to buy a quality scope.
The optics were good, and the reticle was bright. It attached very easily. However, the turn knob to get the thing to come on was the hardest I had ever tried to turn on before. I have other optics, and this was not easy. Also, the design of the turn on knob is also the knob to open the battery compartment. The battery compartment opened with numerous cycles of on-off in one direction. Not good.
went to the range with a friend and borrowed his mkIII for my m4. once it was zeroed at 100 yards on clay pigeons all I had to do was turn the elevation from 1 to 2 and it was dead on at 200 yards. this was really nice so I ordered one as soon as I got the chance and cant wait to take it to the range
Answer: yes
