Question: Will this work on an AR 15 pistol?  Will it hold zero and not fall apart?  Thank you or your help
Document: I was skeptical about putting it on a 12gague shotgun but it worked perfectly. I slapped it on my Pardner Pump just to see if it could hold up. The thing was almost perfectly sighted in at 15 yards when I put it on. I used the little tools it came with and a couple adjustments later it was perfect. It is a little overkill for just shooting cans and pumpkins but it is holding zero dozens of shots later.
My wife was having difficulties with the iron sights on her new Ruger 22/45 Lite and we ordered the VISM Green Dot Sight with Integrated Red Laser to see if it would help. After attaching the unit to the gun's Weaver rail, we took it out to the range and it was already sighted in for both the green dot and the red laser at 15 yards.
I thought the laser would just be a fun way to &#34;shoot from the hip&#34; with the stock folded up. Due to the size, this would also make an ideal sight for a pistol, laser or no laser. At this time, I'm not going to be using it on anything larger than a .223, so hopefully it will hold up and stay zeroed. I'll see how it goes after a few hundred rounds and update if I have any problems.
Do not buy this or anything else that says NCStar! I installed this on my .22  and after 5 shots the green dot stopped working. The laser still works, but wouldn't hold zero. 2nd NCStar scope that I've bought that went bad.
This compact unit can't be beat for the price. And the fact that it also has a laser was the main selling point for me. The green dot is a little large, but adequate and bright enough to see easily. The controls work well and it was easy to zero. I put this optic on a Ruger 10/22. Works great.
when I received this product it was all scratched and scuffed up like someone had dropped it on the cement, also the front lens was crooked i could not zero it in moa dot barely moved when turning the dial, would have been a good product if it was made by a better company (and everyone wonders why china if stealing all are work, if the usa keeps up this kind of craftsmanship).
this is a great sight for the price. its holds up against 7.62x39 recoil with no probelms and holds zero really well.i give this sight four stars because there seems to be two greens dots one on top of the other, maybe i got a defected one but i didnt want to go thru the hassle of return shipping so i just figured out where to hold the dot to be zeroed in.overall i would recommend this neat sight to someone looking for a great plinking target sight.
I bought this for an OA93 AR15 pistol and it is better than the EoTech I had on this weapon previously. This is primarily due to it's compact size, the EoTech was big and heavy, and this sight is all you need in this particular type of application and the laser is nice too.
For any of you that are rating this sight one or two stars you are stupid. This sight is made for airsoft and airsoft ONLY!!! It is not meant for real guns so for any of you people who think it sucks because it doesn't work on your .223 rifle, it's because it's not supposed to!! AIRSOFTERS!!!! Buy this sight. Just buy it.
This is a pistol or air soft sight. Totally not what I was expecting in addition to the size a rail mount riser is required for the use of iron sights. The lenses are tinted and you can't see anything at night with the overly bright green dot. I am a LEO and I am not staking my life on this. What a disappointment!
Answer: yes
