Sig Sauer Optics Expands with LevelPlex Equipped TANGO6

While most precision shooting is typically done static on the range, the tactical and competition world has been pushing the limits of what both rifle and shooter are capable of. Often the shot is not for the ideal seated position on a bench and requires the contortion of the shooter, rifle, or both to make a critical shot.

Critical to success under those circumstances is the shooters ability to know and account for the cant of the weapon system, bringing the optic and barrel into their ideal vertical position. Typically, this has been accomplished through the ubiqutous bubble levels, common to levels in household tools. These levels certainly have worked, but they do have their risks including breaking, not actually being level with the scope (As they are typically mounted seperate of the scope), breaking camo (they are typically neon green), etc.

Sig thinks they have a good solution to that problem using digital technologies. Their latest TANGO6 riflescope featres “LevelPlex”, a digital solution which indicates to the shooter level placement inside the optic itself. As such, the only potential for error or breakage is in the optic itself, not a third party accessory.

Sig claims the LevelPlex technology is “6 times more accurate than a typical bubble level.”

LevelPlex is integrated into Sig Sauers Electro-Optical divisions latest TANGO6 optics. LevelPlex is in three models, “5-30x56mm, 4-24x50mm and 3-18x44mm, while a capped close quarters 1-6x24mm non-LevelPlex model is also available.”

All Sig optics include their “Infinite Guarantee”, which basically means that so long as you dont mess up the optic, they fix it. Reading the numbers, sounds like this will give Vortex’s guarantee a run for its money.

    Any word on battery runtime? Doesn’t seem to be indicated on SIG’s web site. I’d like to mount one on a Galil ACE 308.

    • Harry’s Holsters

      We have 50k hour battery lives on Aimpoint, Sig and Primary Arms red dots. Hopefully this technology will somehow translate to magnified optics. I’d love a battery that would last for one year!

      • Minuteman

        My ideal setup for both my AR and Galil ACE 308 would be my TA02 and TA110 with RMR type mounts for a Leupold Deltapoint pro. But there don’t seem to be any mounts or adapters available for the setup I have in mind I really love ACOGs, just wish they weren’t so finicky about mounting red dots other than the RMR as I stronglt prefer open style sights for red dots instead of looking through a tube. Aimpoint is only so and so, meh. MRO @ 1 doesn’t cut it for me either. I want an open style sight over an ACOG. SIG’s offering looks like a good compromise though, but I need to have some more solid specs before spending the buck. 700 hours, 3k hours. That simply doesn’t cut it. My general requirement in any optic is meet or exceed ACOG LED battery runtime because that is the benchmark for a good magnified scope. That thing is tough as nails and has excellent glass.

        • Harry’s Holsters

          You could always go with a 45 degree mount for the red dot.

          • Minuteman

            In case I don’t find a compatible scope tube mount offset will be the only remaining option indeed.
            What I don’t like about Aimpoint sights as well as the MRO -all of these sights are top notch though- is that I’m looking through a tube and I feel that there’s excessive clutter around the diopter, which obstructs vision. There’s just too much going on. I prefer the EOTech dot as I’m super fast and accurate with it, but EOTech sights are unreliable and have very limited battery runtime. So the best option is an ACOG and an open style red dot sight mounted on top. So far, only RMRs and Doctor Sights will fit. But RMR’s won’t hold zero, are unreliable and I’m not a fan of Doctor sights.
            My objective is too have optics commonality across the board (ACOG LED w/ overhead RDS combo on each and every rifle that I own).

          • Minuteman

            Very interested in this SIG line of optics though. Can’t find anything online about battery life. Which is really make or break for me. You can’t really beat ACOGs , MROs and Aimpoints though. They run and they run and they run. The VCOG is a tank as well, and altough the battery only last 700h, it’ll still be able to operate under daylight conditions.

    Ron Cohen can, and did, mess up the Sig P226.

    And people want to buy OPTICS from him?


    • Flounder

      Can you elaborate on that?

      edit: What did he change about the P226?

      • Minuteman

        QC when downhill when Cohen became CEO. He did the same thing to SIG Sauer as he did to Ruger. SIG quality is back to what it was though, so rest assured.

      • Frank Grimes

        Ron Cohen is the same guy who was hired at Kimber to increase their sales.

        He did so by making them produce a significantly lower quality product with a significantly higher price tag.

        Series 1 Kimbers were awesome, post-Cohen Series 2 Kimbers are products of cost cutting by using all kinds of MIM crap and foregoing QA/QC checks, and stamping “Custom” on all of their assembly line pistols.

        He did the same thing to Sig. A P226 you can buy today is a far lower quality gun than a W. German marked P226 from 15 or so years ago. You’re going to find vastly more (poorly) manufactured MIM parts (made in India!) and overall a more cheaply built lower quality pistol.

        Unless you want a super cool gold plated Kenny Rogers edition P229 “Gambler”, I can’t think of any reason to buy anything Sig in NH currently makes. I would trust a Ruger more.

        If you know how to buy Sig Pro 2022s so you can assure the pistol is fully German made (Ilaflon finish, triple serial numbers, etc) you can get a great pistol.

        I have never seen one made wholly or partly in Exeter, NH that worked, aside from the one so poorly built it was literally 2 feet low at 7 yards. That worked ok.

        • Minuteman

          Just for the sake of the argument, what alloy/steel da/sa pistol would you otherwise suggest? Something CZ or Lionheart? Say if SIG didn’t exist, where would you take your business? I like Lionheart alot but it’s simply too small for my hand as the LH9 was made for Asian hands and outside that market would only do well in the hands of petite framed women. Just my $0.02

          • Frank Grimes


            No issues with CZ, either.

            Though it’s not alloy framed (and my favorite model is not DA/SA), do not discount the H&K P2000 either. They can frequently be found for $600 or less and are absolute top shelf and are more ergonomic than any Sig I’ve ever used.

          • Minuteman

            I think I might go for an Arex Rex Zero 1S. I’m impressed after having seen Tim’s elements & gauntlet test. Maybe it’s time to ditch SIG alltogether.

          • Frank Grimes

            Yeah I can’t speak for their QC being “back to what it used to be” but I don’t think QC matters if the parts are junk to begin with.

            That’s like inspecting dog turds for quality.

            Remember the ATF fiasco when they were testing the P250 in the trials for their new duty pistol? The ATF had so many malfunctions with the P250 that they ran out of the forms they use to officially document malfunctions.

            Sig said that “The ATF placed too much emphasis on reliability”.

            Don’t get me wrong, the ATF doesn’t deserve functional firearms anymore than Nazi Stormtroopers do, but that attitude that Sig had completely sums up the type of products that modern day Sig is putting out.

          • Minuteman

            You’re right! I remember. That’s definitely food for thought man… One note: I have yet to find a google image of a ‘P226 kaboom’. USP on the other hand…. Even 1911s kaboom. I have never in my entire life seen that happen to a P22X series pistol. Has SIG become a different company under Cohen? Most definitely! As for parts being trash, I am still utterly traumatized by the MK25 having failed miserably in Tim’s elements and gauntlet test. There was a time when things like that simply didn’t happen to a SIG pistol…

            Anyway, let’s think real hard about what’s there in the alloy/steel 9mm realm, in random order; WC Protector series, Lionheart, Arex Zero 1S, CZ, Beretta (not a fan of the exposed barrel), Kahr K9, Para Ordnance, SR1911, Hi-Power albeit with trigger job. Did I leave anything out?

            It’s hard to tell man.. I think I’d go for the Protector. Wilson Combat really is in a league of its own.

          • Minuteman

            SIG’s QC is back to what it used to be though. I also like the Wilson Protector VERY much, as I just love 1911s. The only gun with an action, fit and finish matching Wilson is Lionheart. Those LH9s are beauties and of impeccable quality.

  • Ebby123

    This is a step in the right direction.

  • Flounder

    Nathan can you double check that warranty? I know Sig has a multiple part warranty and some parts expire. Although I haven’t gotten a trustworthy answer as to what it actually covers.

  • 22winmag

    Cool tech, but it’s no Leupold.

    Drop it. I dare you.

  • Minuteman

    I like 1911s and P22X’s a whole lot. If my hands weren’t so big I’d jump on the Lionheart boat in a heart beat.

    • Frank Grimes

      Shoot 1911s then 🙂

      • Minuteman

        I love 1911s. This is our pistol, America’s pistol and what our grand fathers, great grandfathers and great great grandfathers went to war with to fight for just causes. It served them fine and what served them fine would serve us fine. 1911s have a soul and so much significant history behind them. I honor and cherish our great nation’s history and have a special place in my heart for the weapons that stood up against tyranny and restored freedom. The weapons of our two great generations are a reminder of what true freedom is all about and that we always ought to defend it, never bowing down to those who dare tread on it. The 1911 is a national symbol, our badge of office.

      • Minuteman

        Thanks for mentioning Beretta, you’ve got me interested in an M9A3.

        • Frank Grimes

          It’s a pig though. Obviously try one first if you have smaller hands.

          • Minuteman

            I have big hands, not like Hickok’s, but they’re big.
