I have a Pulsar thermal scanner and a Sightmark 4K Mini NV scope. I very much like this combo. Having said that, I have had the opportunity to use my friend's Trijicon IR Reap Thermal scope and it is a true game changer. However, this setup is much more expensive. If you got the $ and don't mind spending it, I would recommend a thermal scanner and scope. One thing I have done to avoid having to buy CR123 batteries for my Sightmark is buying a 10,000 mAh external battery pack with a QD lever mount that attaches to my rifle's pic rail directly in front of my 4K Mini (bought mine from a company named Perceptive Outdoor Gear). BTW I use this on my bolt-action hunting rifle (don't have an AR) and I mount my 4K Mini far enough back to get good eye relef, which leaves enough space in front of the scope to mount the external battery. The external battery is supposed to be good for about 8-10 hours.
