Mark III (NCStar) Scopes

[Temporaryscars]

Does anyone else scope slide forward and backwards just ever so slightly?

 

[Brett248Vista]

Is yours on a quick release mount? if so, you need to adjust the tension on the throw lever (the scope manual covers how to adjust it) mine clamps down solid.. But you have to make sure you find the happy medium, not too tight, not too lose. The lever shouldn't require much force to throw it to the locked position, but you should feel it clamping down.

Oh, ok thanks!

To those interested in the MkIII Optic with DDAB Reflex...

Hate to bring this post back from the dead but after considering which scope to buy I've decided to go with MkIII seeing there was an option for reflex sight atop. Being the price was bit steep I started shopping around and was able to find the entire setup for about $100 which is close to what some retailers were asking for just the optic alone..

The ultimate sighting system: MkIII scope with quick disconnect mount, DDAB reflex with mount to go atop the scope sells for about $160+ as a package deal. Since NC sells the optic mount for the reflex separate I decided to piece it together and save couple bucks....

NCStar MRD34 Mark III Tact Scope Adapt 34mm $5.30
NCStar DDAB Cmpt Tac Red Dt Reflex Sight, Blk $38.21
NCStar STM432G 4x32 Cmpt Red/Grn Ill MD $55.19
Item Total: $98.70 +$10 Shipping Manventure Outpost

Maybe more of you might consider this setup now..

Subject: 3x9x42mm rubber armored Mark III tactical scope

Hello,

I purchased your 3x9x42mm rubber armored Mark III tactical scope for my

AR-15

I installed it as per directions, have to tell you I read bad reviews about this scope not holding zero, so I made sure all was tight and secure.

I was very happy with the price and the features. In addition, it performed great today, my first time using it. Everyone loves it.

Here is the problem, I believe the scope is mounted crooked in its factory rings, when looking down the scope my front sight looks like it is leaning right (Its Not)

I was not going to worry about it to much, then today I was shooting it and showing it at the Range for the first time, all the features ect. Everyone loved it but all noticed immediately it was mounted crooked.

I mean everyone that shot it noticed it. I love the looks and performance of this scope. as we all did. However, this is bothering me now since it is not just me but also about 10 other people that noticed it was crooked.

At this point, - What are my options? – is it something I can adjust?


Thank you in advance

The response

Mr. Gerber,

Hi this is Rich from the Tech Support Dept.

Our scopes do carry a Lifetime Limited Warranty. If your scope is defective, we will replace it with a brand new factory replacement.

I’ve attached our Warranty form to this email. If the following tips don’t help with your canted reticle issue, please send the scope in for warranty.

Please fill out the warranty form and send the completed from with your scope to the address on the form. When we receive your scope we will process the warranty and send you a brand new factory replacement. You may add in the notes section of the warranty form, to have one of our “Technicians to hand inspect the replacement before it is shipped”. The Tech will mount the scope on to our jig and make sure the reticle is plumb and level before shipping it.

Below are some tips that may resolve some of the issues with a canted reticle.

Of the canted reticles from a Mark III Tactical scope that I’ve seen, the vast majority can be attributed to an issue with the mount or an installation error.


For the most part the reticle is plumb and level in the scope body, where it is square with the elevation and windage adjustments. It’s usually attributed to the mount, if the unit was properly installed.

We get very few in for warranty, where the reticle is actually crooked in the scope body.

Installation errors that I have seen from other customers:

· You may have the mount rail tension adjusted too tight. If it’s too tight it will pull the scope to the left side, causing the scope to cant left a few degrees.

· When you install the scope, make sure the mount is push down onto the your rifles optics rail, before you begin rotate the clamp tight against your rail.

· Make sure the floating rail, next to the QR lever is level with the rifle’s optics rail before you clamp down on the lever.

Mount issues that may cause scope to have a perceived canted reticle, the QD mount on the Mark III Tactical come in two sections:

· The QD mount base is attached to the scope with two Allen head bolts. Removing these two Allen head bolts will separate it from the scope and the spacer.

· The spacer has a single Allen head bolt. You can loosen the bolt, and reposition the spacer off to one side a little to correct the reticle orientation, to make it more plumb and level.

· Another thing with the spacer, is that it is made from aluminum and it is very easy to hand file. You can file the spacer at an very very slight angle, so when the QR mount base is re-installed it can correct the perceived reticle cant.

· When you are done and are able to fix the reticle cant, please apply some blue Locktite onto the threads on the bolts to make sure they do not come loose under recoil.

· Another option is to reverse the quick release mount. Remove the QR base mount and position the lever onto the left side of the rifle/scope. This will often times correct the cant in the scope.

· Check to see if the mount is parallel with the top of the rifle’s optics rail. Make sure the gap between the rifle’s rail and scope mount is uniform.

· If the small protrusion (see above picture in the red circle) on the QR Mount base (by the quick release lever), this protrusion should sit along the beveled end of the rifles optics rail. If it is sitting on top or partially on top of the rifles optics rail, it will cant the scope to cause the perceived canted reticle. This is usually caused by an out of spec rail (too wide) or the Scopes Quick release base is milled from the factory too narrow. You can file this protrusion smooth with the rest of the base with a hand file, it is soft aluminum and is easy to remove.


Thank you, Rich.

Hope this helps. Ilove this scope

I received my mil-dot Mark III from Amazon ($73, had a GC to use). Build quality seems good and the reticle appears straight and true. The illumination, all knobs and quick mount seem to work well. Will try it at the range this week but seems to be a good scope for the price.

I received my NcStar mark 3 6x42 two weeks ago. I've been out shooting with it. I put about 500 rounds through my rifle and sighted in scope in. It clams great to the gun and it of great build quality. No movement of zero to speak of and great clear optics. i love it and would recommend it to any owner. I plan on purchasing the parts to make it a "Ultimate sight type".

New optics came in and i figured id go back and post pics for 27 cause he asked it features a quick detach a built in laser and the reticle glows bright blue... this thing is sweet... oh and it 3-9x42mm

Did you find you needed a spacer with this scope, I've read that it sits a little low and makes getting to the charge handle difficult. The reason I'm asking is I ordered one and am trying to figure out if I need anything else for it, thanks.

mil dot power setting?

Just got my tactical 3-9x42 today and didn't find anything in the manual about what power setting to use when calculating distance. I'm assuming it's the highest since nothing is marked. Any input on this?

BTW reticle is straight and the only issue with the charging handle I had was not being able to grasp the right side. Still pretty easy to cock it with just the left side

 

[UpstateNY]

Hey guys. I received my armored 3-9x42 with reflex and integrated laser this afternoon. It looks like I'm not having any luck lately. First I had to send back my DTU for firing pin damage, now I find out my new scope has the canted reticle like others have mentioned in this thread.

I read the customer service response above and he gave a few tricks for attempting to correct the issue. Should I bother with any of these or just send the scope back for replacement? I don't really like the idea of having to file pieces of my brand new scope in order to get it working.

On another note, when I use the ~6-9x magnification and I focus the scope on an object, my reticle gets blurry. It looks great at the lower magnifications, but goes out of focus as I start to increase magnification and focus on the object. I can't even make out the mil dots and it all becomes a blur. Should it be doing this? I would think it would be more critical to see the reticle clearly at further distances as opposed to close distances.

Sorry for all the questions, but this is my first set of optics and I'm still trying to figure out how it all works. Thanks!

 

[Brett248Vista]

You need to focus the reticule using the focus ring on the back of the scope. As far as the canted cross hairs, I probably would send it back. I don't know if what was posted above will help or not.

Sorry to hear about your problems.

 

[UpstateNY]

Brett, that is what I was referring to. When I go to say, 6x magnification, and I use the focus ring to bring my target into focus, the reticle starts to gets blurry. This essentially makes the reticle unusable at 6+ magnifications. Do others see this issue with their Mark IIIs? Could there be something wrong with my optics as well?

Use the focus ring to bring the reticule into sharp focus. The target may not be crystal clear that isn't abnormal, but the ret should be sharp.

 

[UpstateNY]

That seems a little odd. So you're basically saying that you can't have both the target and reticle in focus at that same time, at higher magnifications? Is this normal on all scopes?
