    Edited 04/27 to add - Per Steiner Customer Service, there is no plan to introduce a rail mount option. You're limited to "slip on" or "clamp on" or "how do you say Germans have a twisted sense of humor" mounting options.

    Greetings all. As stated in the C35 Gen 1 thread, I was primed and ready to jump on the grenade. When the Gen 2 dropped and I ordered it the morning after I saw it appear on Gunbroker.

    The unit comes with batteries, cables, a charger and no way to mount it on an optic. The rail mount is not yet available, and I can't wait till it is because while the slip on is quite adequate, you're limited to a very specific bell diameter without swapping about. I bit the bullet and bought a Burris Smartclip 59mm for my VX-6 3x18x50.

    Initial impressions are positive. Unit takes two 18650s. They can be hot swapped and it only needs one to run. I only did that trick once because with two in, I was never in the field more than ~5 hours and they were never in any danger of running out.

    Start up to image is about 10 seconds. Menus is easy. Zeroing was easy for me - I got lucky and everything was in enough alignment that I was minute of pig from the first shot. The VX-6 is a surprisingly good host - from what I'd read on the interwebz, 6X is where pixelation is so bad you can't make out a pig from a manbearpig. Horseshit. I shot most groups at 18X. Caveat - the eyebox error is about .0001mm - but, sitting on a cart that has a rest built in, you have that luxury. In all seriousness, about 8X is where you go to noticeable pixels and at 18 you're maybe 16 bit resolution BUT, more on that later.

    I was extremely skeptical about the slip on clamp. I stand corrected in that the system works somewhere between well enough and very well. If you're willing to put in the time and work at getting repeatable to the point you're zoomed in to 18X and referencing exactly where your reticle falls against, say, the menu screen - results can be very very acceptable. With the limitation of trying to get it moving pretty quickly, results are still minute of pig with no worries.

    In practice, in the field, we had a textbook coyote hunt. I'm using a 20" Grendel with Hornady 123 SSTs. Put a pig carcass from the afternoon hunt in a field, threw out a call, had two yotes come in. I told my buddy to throw out a countdown - he said he wanted me to get something with the new toy and that he would shoot on me. For the record he has one of the newer AGM 640 50mm dedicated scope type things and that is a pretty slick unit as well. I watched the coyotes work toward the carcass and was playing the with zoom. True story, I got up to 18X but was steady and was watching a 16 bit dog walk, sit down and look at me. I could make out the ears at 170 yards. I threw out a 3, 2, 1 and the coyote was DRT. My buddy had put down his gun down thinking they would carry on to the carcass and didn't get any shot as a result.

    When it comes to accuracy and return to zero - its good enough. All shots are 100 yards. I witness marked the unit and that keeps it level enough most of the time vs reticle reference. I zoomed into 18X and referenced off where the reticle fell under the letter A in the menu. If I made it a point to fuss with it and try to get very very close to the point I'd based an adjusted group from, it is MOA-ish capable across multiple remove/remount. The rifle is a sub MOA gun and makes everything involved look easy, so it had a running start. The smallest group was a series of removing and remounting 4x, shooting 2 rounds at a time at 18X with all the care. Basically the other groups represent various zoom and effort of alignment combos, but the real test is coming soon. Next range trip I'm going to shoot 50 rounds, one at a time, so 50 RTZ remounts using the external reference marks ONLY and taking what I get. I am going to note WHERE the reticle falls but I'm not going to correct. From there, I believe that I'll be able to figure out the approximate box where its 1, 2, 3, 4 MOA off based on the reference. From there I should be able to determine the ability to know I'm going to hit, say a 2x2" reasonably reliably. I'm very curious to see the results.

    I'd guess around then you'll be able to buy a rail mount :rolleyes:

    Menu allows for 3 weapon profiles, screen can be dimmed down to be easier on the eyes, I'm generally happy with the purchase. This could replace my 'ol Armasight Zeus the way things are going.

    Horizontal string was 1, remove, 1 remove, 1

    3, remove, 3, lower mag and only minor fussiness over reticle alignment

    2, 2, 2 with a little reference effort and 2, 2, 2,2 - every comma = remount until it was as good as I could hope for and then very careful pressss of the trigger.

    I found and bought the Burris eyepiece adapter to see how it did as a spotter. The answer is "not great". The Burris eyepiece limits FOV and is mainly a thread protector.

    So, more soon. I need to swap the mount and then get back out to the range. I'm waiting on a couple things to come in but I'm excited about the potential.

    Final thought, I want a rail mount - but - the way the unit is shaped I dunno how it is going to work clearance wise with 1.5" mounts.

    Third hunt update in post 50

    Wow, that's not a bit of a change, that thing is entirely different.

    My trials and tribulations in running the rail-mount stem exclusively from the scope-to-thermal offset that happens on rail-mounted things. The objective mount looks weak, but it should align far more naturally than rail mounting. That said, rail mounting is hella more secure, and doesn't hang a weight out on the end of my scope...

    Thanks for the details, glad it was a success.
     
    1) I was surprised to see the unit does NOT have bolt holes on the underside. I suspect it is going to use a system like the Burris where it threads the rear into a mount that comes under.. or goes backwards??? Fair warning, based on how the underside of the unit is shaped, I don't see how a rail could articulate under the footprint of the unit @ 1.5" rail to centerline. I will not be shocked if Steiner eventually says... yeah.... no soup for you. At that point all I'll be able to do is shrug and accept that I'll restrict the other guns that are set for it to 30mm/34mm tubes AKA a razor 1-X or whatever direction I end up going for another mount. I do agree that the concept of trusting the slip on clamp against gravity over time seems like a losing proposition as there is a material in there to avoid marring the scope and blah blah blah I don't like the gun being slung with it on. I have a feeling that ends with bringing the gun up and realizing it isn't attached as it lays in a field behind you once that material has too many reps or whatever. Gravity always wins. Locking metal/metal better.

    2) It does record, and very easily - click the menu knob counter clockwise to start and stop video. I haven't even begun to mess with that and didn't think about it for the coyotes. I'll mess with all that stuff down the line, I'm back in reality in the office and raising children and so forth until my next trip in May. Hopefully I'll be able to report back more with regard to repeatability then.
     
    I think you are on to something, would be surprised if Steiner releases a rail mount for it.

    All gen 1 C35 were delivered without the rail mount in Europe as far as I know, hence having to use adapters to scope mount.
     
    Steiner told me they were going to release a rail mount but then the rep kindly and honestly said he has not seen or handled it and that they were waiting on zee Germans.

    If they do NOT release a rail mount, I predict these do not catch on like wild fire. It might allow for MOA out to 300-350 with real effort, but that will take a contentious user with a little luck and a lot of patience.

    Americans like rails. At the street price the Steiner would likely still be the best deal going for a very specific niche however if I knew for a fact it would never be rail mounted I don't know that I would have bought - but - it has proven to me that the clip on concept is viable. You'd be looking at $3500 in hand with a clamp in general and there are a lot of other options at that price point that are either dedicated or have a clip built in.
     
    Per Steiner, they tried, it doesn't. Hoping to hit the range tomorrow and put it through the paces again.

    The Pulsar PSP-V looks like it would have promise and I think non standardized thread pitches are the work of the devil in this kind of application.

    Looking at that mount, I don't see any threads in there - it appears to be a rubber insert?

    That would make me VERY nervous with the amount of meat involved. The slip on/clamp on has a lot of purchase on the bell but it is still in the back of my head that gravity can and will win in time.

    At the end of this rainbow, surely we can get a mount that is metal/metal with some sort of interface for locking in as opposed to clamping and hoping.

    That's not correct!
    When you look at the detailed photos, you can see the aluminum ring that has threads on its internal surface.
    2024_04_23_08_14_34_Window.jpg

    The way the mount works is that you thread your device into this ring. The ring has a spherical surface on its outer diameter, allowing you to adjust the angle of the thermal device until it matches your scope. Then you tighten the clamp around the threaded ring, locking the assembly into place.
     
    Well good, because Steiner sent me a message today -

    "We have been informed that there is no plans for picatinny rail mounts to be produced for these devices.
    They are only able to be used with objective clip on adaptors."

    ROFL. They got me.

    Gonna need one of those PSP-V's with the correct thread pattern.

    Had a great range trip today. I didn't do extensive testing with the thermal, just some zero verification and then was working back to 500 with the rifle/scope combo that this thermal forced. That has worked out very well in that I didn't realize my VX-6 and Grendel were meant to be, but the reticle lines up *perfectly* back to 500 yards in practice so on some level I have to thank them.

    I just ordered a 30mm smart clip. I'm still amazed Steiner went backwards with a Gen 2 unit and is not planning to offer a rail mount...

    While the unit has 3 profiles, it is less than convenient to have to swap the damn smart clips. This also means I'm down close to $400 between two clips. I'll be running some tests soon with regard to repeatability, quickly, using the slip ons. I'm going to set up one of the profiles for a 22 which will allow for some extensive zero shift testing.

    .... praying for a clever and timely aftermarket solution.

    It is especially mind-boggling since there is no reason for this step backwards.
    It used to be the case that mounting such devices directly to your weapon via a rail mount was illegal in Germany. That's why we even have all these scope objective bell mounts. I hate them, from an engineering perspective they are a terrible idea. But it was the only legal solution.
    However, the laws have actually changed for the better. Nowadays most municipalities allow direct weapon mounting for hunting. So it's a mystery why Steiner decided to not even include a hard mounting point at the housing. If you're too lazy to design the Picatinny mount, fine. But at least give us a housing mounting option.
     
    Considering the Gen 2 is supposed to be an upgrayydd, and has beeter tech specs, upon reflection I really am disappointed. This limits the utility tremendously by comparison.

    Well, I'm going to shoot it - a lot - with two grendels and the 22.

    Looking forward to determining the accuracy potential and repeatability.

    My man. Please do. More pics would be greatly appreciated of where there is interference as our set ups are similar.

    I got the 30mm ring in and it can't be indexed.

    Steiner is sending me another one of the knurled rings for the back of the unit to give the depth necessary, and it should be able to be flipped to give some chance at indexing but :unsure::unsure::unsure: as to the thought process.

    So what you're saying is it would fit under a 30/34/ACOG without modification....

    Those are my primary optics I'm trying to use at night - I can live with the slip on crap for the 50mm objective should it be time for that system.

    1.5"?
     
    Three cheers for Trash Panda. Wish I could get back another little bit on the ACOG but there are plenty of options that will work fine.

    For the money, it is still a great deal. While it has fleas, they all have fleas, and the screen resolution allows for use of 10X+if you have a good stable platform and aren't in a rush - but I think that usually applies to 10X magnification anyway.

    Fellas, I found a solution that I hope will work. The plan is to spin an adapter (40mm outer diameter) that will thread into the 33.5x.75m part of the c35. This adapter will be cut roughly 2 inches long. The plan is then to use an adm aimpoint mount with upgraded 40mm recon ring to secure it to the rifle. With a lower 1/3 adm mount, this should sit level with a badger 1.70 c1.

    Frustration with the rail mount situation. I'm looking at getting the mount milled a little flatter so that it can fit under a couple other scopes and hopefully to allow a second bolt to secure it - currently it only uses one due to being flipped.

    My last planned trip got cancelled due to work but I've got one coming up soon. I will likely put at least another 10-12 hours on it and will have more academic and practical feedback at that point.
     
    TLDR - The Burris Clip on adapter can be made to work and is in practice, in the field, minute of pig repeatable. Detailed RTZ testing later.


    So, the universe works in mysterious ways and I ended up with a NOX35 that put the Steiner onto my oldest son's rifle. He's shooting a 556 with the OG 1-4 Razor, which is a great match up.

    All these groups are fired from a not tactical tripod, i.e. less than $100 and just has a valley to rest in, not a multi thousand dollar hydroball clamped in situation, all shot at 90 yards.

    We've checked it across the three days we weren't setting rained out on steel by going off/on/off/on, firing three rounds on each gong for each iteration. Day three I needed a clean gong to verify something else so we have six shots on one, but it went off and on in between and produced two groups where I could see the shift, but predictably so. In practice, they have seen two pigs and killed two pigs this trip - we've been hampered by that tropical storm a bit, but have eaten our way through it and managed a couple pigs, a coyote, and some quality time nonetheless.

    So - takeaway is I'd like to thin out the top of the mount so that it slides under a 30mm scope a little more easily, but I suspect on a concrete bench and bag situation we're gonna find a 1.5" rifle can reliably produce say 4" groups clipped off and on. Not perfect, but what is - in practice, this beats humping a second rifle out there and is for sure minute of pig.

    Hanging gong is 9", post gong is 6".

    Slightly redacted email to Steiner...

    First, the gigantic step backwards from a Gen 1 unit being rail mountable to the Gen 2 unit being exceptionally limited by comparison is, to be frank, laughable. The mounting options for the C35 make it analogous to an athlete bound to a wheelchair. The tech specs mean the 2nd gen should be hands down the best value on the market, yet I can't recommend it...
    I *fully* understand the concept of the slip on clamps as well as the capability allowed with a rail mount. I bought the C35 with the belief a rail mount would eventually be released...
    Slip on clamps do not allow use with an ACOG or any scope that has a short step in the tube on the front end - i.e. Vortex Razors - which are historically two of the best pairings with clip ons...Slip on clamps require significant work to get realigned...
    I did find that using a Burris adapter, I've been able to create an imperfect rail clamp. It only fits under 30-ish MM scope bodies which means it doesn't work with some of the optics I really hoped to use. Attached is a picture of it in front of my son's scope. If you'll note, a slightly shorter and skinnier adapter wouldn't be half bad for people running up to 35MM/ACOGs...
    You need a rail mount for the AR dominated US market. It is that simple. I can't believe it was released without the capability. I'm surprised you sell the unit without at least one method to mount it in general.

    Unless they machine an appropriate mount, we're left with adapters. I'll be curious to see what they or the aftermarket come up with as the best solution. It is a fantastic unit from the standpoint of image, screen resolution, battery life etc but it's outright silly to say only factory option is slip on.

    Aftermarket is working on it. It takes a little time, unfortunately.

    I'll be curious to see if anyone comes up with a gadget that fits on a rail with a release under the batteries.

    Its such a great tool other than that massive detail. Gen three, they could position the batteries on a side to prevent the overhang on both sides.
     
    Steiner really impressed this trip. I got the bigger coyote at 305 yards. Images are through a Leupold VX6 HD 3x18 at 3X and 18X.

    The pics with my son and an NOX 35 are pigs that were hit with on a countdown and a let him have all photo credit, but the smaller one specifically I'm pretty sure was all me ;)

    Steiner notes - I zero'd it before the hunt and left the unit on the gun as our cameras showed all activity at night. I verified zero on site with minimal adjustment. The fucking site got turned on in a case (?) as it went in with full batteries and 10 hours later was dead as a doornail, but it never displayed any issues the rest of the trip so I'm contemplating how to make sure the on button is shielded in the future.

    Without any on/off zero shift drama, I have to say I was very, very happy with the performance.
