Looking at one of these options and wondering if any users have experience with one or preferably both and might be able to guide me in the right direction. I’d like one thermal scope that can be swapped between flat top AR’s in 5.56 and 6.8 SPC and a bolt action 7mm-08. I’d use the set up to shoot nuisance feral hogs, beavers, and coyotes on my property. Typical range of shots on target would be in the 75 to 100 yard range and not likely to ever exceed 125 yards.

I'd suggest the Rattler style with single ADM mount for transferring among guns. IIRC the 50x640s have higher base magnification so FOV is reduced. I got a rabbit @ 100 yds with a 35 640 - 16x magnification.

I have the Iray and I like it a lot. It is currently on a 6.8 but think I’m going to grand put it on a bolt gun real soon

I like the Bolt much better. I just got back out of the rabbit hole today and picked the IRAY Rico RH50V2. No internal battery to ever go bad years down the road either. They are on sale right now for 3900 at most places.

Let me maybe save you some money. If the 75 to 125 yard shots are on hogs and coyotes, you could get away with a 384 resolution readily. Beavers on the bank would not be an issue either at that range and you could still do beaver in the water. After all, you should be able to zero with something like a tiny hand warmer or ice cute at 100 yards .

Don't get me wrong, more resolution is better than less and if you can and want to afford more, you certainly should go with 640 or better, but if money is tight, consider 384.

I think I would take AGM over Infriray because of the processing (not refresh rate) lag common to a lot of Infiray scopes.

According to our tech rep "With the distances and weapons mentioned on his post I would focus on the base magnification being lower on the adder so he will have a wider FOV, and the value of the American Defense QD mount that ships with the unit allowing his to move from the weapons he listed right out of the box with a true return to zero mount, without having to spend more money on additional mounts/rings.

Pulsar Thermion 2 XG50-640 is on sale for about the same price point too.

I was looking at many of the options discussed in this thread and ended up finding a great deal on a Bering Super Hogster A3, and I'll be honest - it's a much nicer scope than what I'd anticipated considering the reviews. It's just a really clean image and it's compact and easy to use. I couldn't be happier with it. Just a consideration. I think the Hogster is more of a mid-range scope than the Adder & such (I believe Bolt is also more of a mid-range scope).

Thanks for all the sage advice. I suppose I might occasionally take shots out to 150 yards (and it would be nice to have the optics to allow that) even though most of my shots on target would be within 100 yards. I have an AGM Rattler already, but it is a very low resolution model (I think maybe 256?), and it is fine for up to 75 yard shots, but at 100 yards, it doesn't give me the detail I'd like. I guess that's why I am thinking about 640k resolution although I appreciate the poster who put a plug in for 384k. That would save me money for sure, but would I regret not getting a 640? That's the question in my mind. I do like the idea of the "value added" ADM mount that comes with the Adder.

You have not stated which model you're considering, but I have some comments.

I used an AGM TS35-384 Adder for a while, and there are several reasons I would recommend it...one reason being battery life. It will run for a good long while on a single charge. I think 10 or 12 hours is not beyond what it can provide.

Another reason is the User Interface. Before I had the Adder I used a Pulsar (damned if I can think of the name of the model) having a bunch of buttons on top. I found operating the thing to be a little tricky because it was kind of hard to keep track of all those buttons by feel. It was a very good unit and still is, but I wanted the Adder because of the more appealing form factor. As a bonus I found it much easier to run through settings and options and stuff with the control scheme it offers. MUCH easier.

The Adder's performance was perfectly acceptable, too. Identifying animals beyond 100 yards was no problem whatsoever. Being sure of what you're about to shoot is obviously a priority, but even with a less capable optic you can often ID critters by cues other than body shape. A sounder of hogs is one of the most easily recognizable subjects just because of the way they move, the composition of the group in terms of different body sizes, etc. etc. But having an optic that clearly shows body shape at distance is highly desirable---the more ways of confirming the better. Coyotes and other critters that may roam at night in much smaller numbers can be more challenging to identify.

I think a 384 Adder would serve you well. If you want better for whatever reason, then by all means stretch it out and snag a 640. Overkill is not a bad thing in this pursuit. Bottom line is, I think you can't go wrong with the Adder.
