Konus Spotting Scope Review

Up for review today is the Konus Spotting Scope 20-60x 80mm which I purchased from Midway USA  on sale for $198.00. Midway has some of the best prices around and I have good experiences both of the times I have had to contact customer service.

A decent spotting scope is a necessity for high power rifle shooting. The Konus scope has been talked about quite a bit with an assortment of good reviews, and Jim Owens seems to like it.

The Konus has a variable zoom from 20x to 60x and an 80mm objective lens with a sun shade. It weighs just under four pounds and is about 17" long. Here is the picture of the box that the scope comes packaged in.


Once you open the box you can see the carrying case that comes with the scope. The carrying case is kind of thin and nothing special but it helps keep everything together.


Unzipping the carrying case reveals the scope itself and the accessories that come with it. Included are a camera adapter and a plastic table top tripod.


The tripod works acceptably on the table but it is a bit wobbly and apt to tip over. I will be looking for a replacement tripod in the near future but the included one works for now.

When I first started to use the scope, the zoom adjustment was VERY tight and was difficult to turn. The eyepiece would come unscrewed from the force of turning the zoom. After a few minutes of use and turning the zoom and tightening the eyepiece, the tightness has appeared to go away and it is adjusting smoothly for now. I hope that it stays this way.

The scope also comes with a camera adapter for taking pictures. It screws on to the eyepiece and allows you to adjust the zoom even when installed.



Once I had it unpacked and setup and finished playing with the adjustments, I settled in to shoot and try it out. Overall I was impressed with the optics and the quality of the image. Even when the zoom was cranked all the way up the image was clear and color was close to normal. Having only used this scope two times now I would not hesitate to recommend it to some one else as long as you plan on getting another tripod.

I had intended to take pictures with my camera attached but I forgot to bring the camera to range so I took a few shots with my cell phone camera. I am hesitant to put them up since they were taken with a shaky cell phone but I will put one up and post another image that was taken by another reviewer with a better camera.

Leupold Mark AR Review

I have been in the market for some decent optics for my flat-top AR. With the economy the way it is I initially tried to keep the cost down and crashed and burned with the NCStar Mark III. Thankfully Midway USA made the recovery much easier with their no hassle return policy. After that experience I put aside some money for a little while until I was able to save up enough to order a Leupold Mark AR from Optics Planet with a coupon. I also purchased a one-piece Burris Scope Mount from Midway to go with the scope.

The Leupold Mark AR comes in a 1.5-4x20 model and a 3-9x40 model. You can buy it in Duplxe or Mildot reticles and the lenses are coated with Leupold's Multicoat 4 System. This system is supposed to result in increased brightness, contrast, and clarity. The view through the scope looked good to me although I did have some issues making out 22 cal holes at 100yds.



I bought the 3-9x40 version with the Mildot Reticle. It is a one inch tube in matte finish. 
The elevation knob is adjustable in 1/2 moa increments and includes a built in bullet drop compensator calibrated for the M193 round. A 55gr bullet at 3200fps. Leupold offers the ability to purchase a custom calibrated compensator for the load of your choice.
I mounted the scope to my AR using a Burris one piece mount.  This particular mount is really intended for AR platforms with shorter stocks. I was very impressed with the amount of eye-relief that this scope offered. The optics were clear and easy to see.
For the real test I used some more of the Black Hills 55 gr ammo that I got on sale back before the election of '08. I bought a whole lot at the time, one because I got a good deal, two because I was under the impression that Black Hills was some good stuff. I have gone through quite a lot of this in the past few years and I have not been impressed. It is supposed to be 3200fps but I have had it chrono from 2800 to about 3120 and everywhere in between. Not the most accurate in the world but it was cheap and good for plinking.

I didn't have a lot of time this day so I got it sighted in and then started firing 3 round groups starting at 9x. 3 at 9x, 3 at 8x and so on down to 3x. You can see the results here 21 shots at 100yds. Not the best shooting in the world but I am happy to report that I did not have any real change in the point of Impact like I did with the NCStar. The next chance I get I will take some of my handloads out and practice for a little while. Even though the Leupold and the mount together were about four times the cost of the NCStar, there is a noticeable difference in the quality and I think it was worth saving up to purchase.

NC Star Mark III Review

Up for review this month is the NC Star Mark III Tactical Scope. I got this from Midway with a coupon for about $115. I was kind of apprehensive about this purchase as I had read a couple of not so hot reviews and I am usually of the mind that you get what you pay for.

Anyhow this is a 3 to 9 variable power scope with illuminated mildot reticules. It comes with an integrated quick release weaver style mount. My intention was to put this scope one of my flat top ARs.




The package from Midway was packaged adequately as usual and I pulled the scope box out to take a look. The box packaging looked decent and I did not see any damage to the box.






 The end of the box shows the 3-9X with a 42mm objective. the actual model number is STM3942G.






I carefully removed the scope from the box and checked it out. One of the reasons that I picked this one is that it has the built in bullet drop compensator that is calibrated for 223. It is actually calibrated for a 55gr M193 round and I usually shoot 69 or 75 gr. Supposedly you sight it in for 100 yds and then you can adjust the compensator out to 500 yds. I never actually got that far with it.




Some of the negative reviews I read indicated that the mount did not hold onto the rail very well and would come loose. I followed the instructions and mounted mine, then put a drop of loctite on the locking screw.
I do not forsee this thing coming loose and after 200 rds it has not budged at all. Here is a shot if it mounted on my AR.




Here is another shot zoomed out a little bit with the included dust covers on.








Now I have never had a scope with illuminated reticules before so I wanted to try this out. Supposedly the illumination will help in low light situations. However I found that even on the dimmest settings the illumination destroyed my night vision and I could barely see anything well enough to shoot it. Here is a shot from the aft end of the scope at night.
It is a little out of focus but you can get the idea, it is very bright and that is lowest setting.


The view was only a little better with the green light. Again it is a little out of focus but you get the point I hope.








Alright enough of the fancy stuff how well does it shoot? I was not expecting great clarity out of a scope this price but at 100yds and with the scope at maximum magnification 9x, I could make out most ( not all ) of the 22 cal holes. Not that bad I suppose. I went through 200rds of 55gr ball ammo that I got on sale back before the election of 08. Not the most accurate stuff in the world but it puts holes in the paper. As I was shooting something seemed strange and I was not sure what was going on. So I opened up the bipod and set up the bench to make myself  nice and stable. I got the rifle sighted in so that I could put my shots into a group the size of a quarter at 100yds with the scope at  9x.


Then I loaded up the magazine hunkered down and put 6 shots into the center of the target. I then carefully moved the power from 9x to 8x and took 3 more shots. Then moved the power to 7x and took 3 more shots. I continued this at 6x, 5x, 4x, and finally 3x. You can see the results to the right. With each change in power the point of impact changed. After 5x I was no longer even on the paper. At this point I was kind of disgusted and it was starting to get late so I called it a day.


I don't know about you but the point of impact should not be moving when I change the magnification level. I could accept a little bit of a change but to be off the paper is unacceptable. There is supposed to be a lifetime warranty from NCStar on these. At this point I am glad I bought this with my American Express as I can definitely get my money back. I am undecided if I should deal with trying to get warranty replacement or just return it. At this juncture in time I cannot recommend one of these scopes. Let me know what you think in the comments.
