Solid Scope for the Money with some Limitations
By John Deaux
I put this Triple Duty 8.5-25x40mm, model number SM13011, atop a Lewis Machine Tools LMT308 yesterday evening, then took it to the 1000 yard range at Quantico Marine Base. Yeah, yeah: Expensive rifle cheap glass. let's just say it may not be the right scope but it's the right now scope. I selected it on the recommendation of a fellow at a local shop who could have steered me into some pricier models but he said that he found it to be a fine scope on his own rifle until he could save up for something top of the line. I think that is a valid assessment.I didn't have the benefit of a proper boresight, being pressed for time and facilities I just locked it on the gun with an American Defense Recon 30 quick release mount and got to business. I was able to get holes in paper at 1000 yards after 15 rounds and then had five hits. Three hits--while in the 7-ring--landed within a silver dollar which exceeded my goals for the day as this was my first shooting at this distance ever. I did this at 8.5x magnification. Clarity was sufficient at 8.5x to 12x (I didn't have need for more for my purposes) and all the functions (focus, windage, elevation, diopter) worked fine.A totally valid complaint is that this scope ought to have somewhat more vertical adjustment. Mine had 60.75 MOA of throw from low to high. I had to apply ridiculous holdover to make it happen even at maximum elevation adjustment. I literally put the top of the heavy post even with the top of a berm behind the target--the crosshairs were on the big plywood "21" of my lane. A 20 MOA base would be a requirement for this scope for 1000-yard work, and you need to keep in mind that this will just bring you up to center of mass even at max elevation adjustment. But there are plenty of legit scopes out there with less adjustment than this one.I am ambivalent on the eye relief. It tends to be a little sharp in the dropoff and if you move a little side to side you can lose sight picture. You have to be settled down behind it. I can see how someone could be bothered by it but I was able to make it work and quick.The illuminated reticle feels a little like a gimmick to me, but it could be of use under certain circumstances and it is nice to have a choice of green or red and some brightness settings. The illumination is of the entire mil-dot portion in the middle. Not the heavy posts to the outside.Speaking of mil-dots, this scope features a mil-dot reticle but uses 1/8 Minute of Angle adjustments on the turrets. So, just keep in mind that 1 MOA at 100 Yards is 1 inch, but 1 MIL at 100 Yards is 9.14cm or 3.6 inches. So, bottom line you just need to keep both those systems in mind as you use it. One dot off to the right on a 100 yard boresight equals a 29-click adjustment.Speaking of the turrets and knobs in general. They require some work to get going. The magnification ring in particular was a little tight and I found it the most bothersome of the bunch but over all I prefer this stuff tight at the start as long as it doesn't get all sloppy later on. As for the turrets with the adjustments being 1/8 MOA I would have expected the tiny little click of tiny little gears and it felt a lot beefier than I expected. The turrets have what I consider a strange peculiarity: Each full revolution is 8.5 MOA. Printed on the turret you get 1 to 7, gradated off in 1/8 MOA increments, then a set of lines showing how far up and down the turret is with lines protruding horizontaly left and right from a vertical line, each one indicating 8.5 MOA--which was a bit of a head scratcher in itself--then you get another half MOA to complete the rotation back to 1. By the way, I take that 1/8 MOA adjustment precision with a grain of salt.Long term durability is something that I cannot comment on as 20 rounds of .308 is not enough of a test. I was pretty gentle with my work M4 when it had an ACOG on it, I am even moreso with this sort of scope and wouldn't recommend banging it about, laying it on its side to rest on the windage turret or parallax knob, or other tomfoolery.Regarding the glass itself, I had no problems on daylight. The fellow who sold it to me said that he loses about 15 minutes of daylight at dawn and dusk compared to fellows with better coatings, which is a consideration.I spent $239 for it. I thought it a pretty good deal at that price. For anything less than $200 I would think it certainly worth it, even if it turns out later on that you don't like some of its lower-quality characteristics. It is probably a good learner scope and you can probably use it to figure out what you want later on. I think one's ability to use this scope is only limited by one's limitations, provided you don't get a bad build which is completely possible given where it comes from, the People's Republic of China.

damn good scope
By Clayton D. Davis
This scope is everything I could want for my AR. The mounts that come with this scope suck, but the scope itself is truly amazing. I've got this mounted to my Rock River Varmint A4 24" and I'm glad I ordered the 8.5-25x version instead of the 4-16x. The extra magnification is really nice when doing 1/4" groups @ 200 yds. The sight picture is nice and crisp throughout the magnification range, and the grren / red illuminated reticle is nice for low light environments. The lockable turrets on the windage and elevation knobs are nice and clean and parallax side focus is a nice feature to have over the adjustable objective lens that many other scopes feature. For the money I could never see paying any more for a scope when this thing does everything a much more expensive scope does just as good. I looked at a lot of scopes before finally concluding on this one and liked this scope better than the nikons and bushnells that I looked at that cost about 3 times as much as this Sightmark did.You can not go wrong with this scope. Buy it.

By Scott ODonnell
I loved the price of the scope. I watched and waited for it to drop to $148 and bought it. I based my order on reading reviews on amazon. I mounted the scope using Weaver 30mm High rings on a UAG base for my Remington 700 SPS Varmint 223. I probably could have went with medium rings. Today was the first day at the range, and zeroing it. It stayed solid at 100yds, I was placing rounds on top of each other in the bullseye. I have to give the gun a lot of that credit too....what an awesome rifle.As for the scope; I found it hard to get the right eye relief. It was difficult to zoom in to 25x and get the target in focus. I had to zoom out to about 16x at 100yds to get it focused, but I could still see where my shots were hitting. I know that you are supposed to focus first and then it should be good throughout the zooming, but it didn't seem to work for me. I had trouble getting it into the lowest 8.5x. It seemed to need to be forced a little. I like the high turrets and the 1/8 clicks.Ranging with the mil-dots sees awkward to me. Per the userguide, the mil-dots are Nato-standard. I dont really know what that is, and the little guide they send detailing how many inches each mildot represents at each power level, is impossible to remember as there is no "mil" setting on the power ring. For the price, the scope is accurate and solid. I might be able to make use of the Nato mildots. Perhaps I just need to be more educated in this standard. I am pretty much going to use this rifle/scope combo for target shooting and the occassional 3-gun comp where a precision rifle is needed. This scope will do just fine for my needs.9-8-12Update:I corrected the focus issue. I removed the scope from the rings and then remounted it and it worked perfect. Don't know the why or how, but it fixed the problem. Found out from Sightmark directly that mil-setting is at 10x.Sightmark is quick to repsond to questions and concerns, even through their facebook page. Sightmark as a company gets two big thumbs up.
