Armasight hurting accuracy?

I have a Zeus Pro 50mm 640 30hz model on my 308 and can only seem to group 2-3 MOA at 100 yds with it. That gun with my day optic (nightforce 2.5-10x24) will shoot .75 MOA. I was wondering if others experienced the same problem or I need to contact Armasight? Any input would be great. Thanks

Really it's a thermal camera not a precision day optic. I'd think you'd need to spend at least twice to 3x as much to get precision. What we have is probably more meant to spray a column of guys with 50 cal or 20mm from an apc. It's good enough.

Sounds like product trouble. TxLawman has been using them for awhile and never misses!!:). BANG BANG. On a side note are you shooting the exact same way you would with the day scope??

Thanks for the replies. I do get to zero both in an indoor 100yd range from a bench. I've still hit plenty of things, it's minute of pig no problem. I just wondered if folks got the same type groups with the thermal as they did with their day optics.

Are you able to get the same point of aim every time you pull the trigger? There's a big difference and shooting at 10 X versus the three or four acts of a 50 mm thermal weapon sight. You also have an issue maintaining the same exact point of aim with a heat signature.

I tend to shoot the group at 2x digital zoom, so that would be 4x optical, as I have 2-8 unit. I will try a group at 4x with the day optic this week.

I've tried three different ways to aim center. Here's what I've tried and the last one seems to be the best one for me. 1) used the smallest hand warmer I could find, it still was too big a heat signature 2) cut a very small square 1"X1" and put cross hairs on the edge of that 3) cut horizontal and vertical openings that I use to align the cross hairs up with, it's had best results so far

I'm own to suggestions if you guys have any. I have the new style ADM mount on it and that feels right, no play.

Todd sights his in by putting a cold water bottle on a stump and if he can hit it 50 yds I think, then the gun is good to go, minute of pig if that is what you are killing is good to go. People get to anal about precision with night vision and thermals, it is not necessary.

If I read that right you are good at a indoor range with both on a bench. So?? You are good to go then. There is not a problem.

Not as accurate as a day scope but I think it's because of the sight picture not showing enough details to consistently shoot m.o.a. at 100+ yds. I shoot steel with mine and rather than holding on a small spot as with day scope's I have to guess center by using the whole target. At 100-200 yds this is a little difficult.

I get different results shooting in the same environment and position. Can shoot a sub MOA group, pop off day optic put on Armasight and goes to 3 MOA.

As for steel, I can hit a mini popper consistently at 100, move to 200 and hit it one out of three with the Armasight. Hit it all day with day optics.

Based on replies, minute of pig is what to expect. I will go with that.

I have a 42mm Zues. A year back give or take I experienced a 3 to 4 group. But found the screws on the mount were just a little loose. When I set or check the 0, I use a hand warmer. Cut one in half. Dump out half of the material, fold and staple on a sheet of copy paper. Then zoom to 4x.

Like slim, I use a scaled down handwarmer and then I work to shoot the exact same spot every time on the highest magnification possible. This allows me to aim small and hit small. That gets me the best groups.

I don't use the water bottles anymore I use a 1" thermal target from night vision guys. Part of the problem is thermal blooms even a small hot or cold target looks bigger with the bloom so grouping seems to suffer. Now that I'm using the small thermal squares I am able to dial it in very tight. But I also zero all my thermals at 50 yards no need for more in my opinion.

I changed suppressors on a 6.8SPC rifle (upper from hdfireman) and resighted at 1" high at 100 yards, my groupings were about 1.5" (shot groups of 3 or 4 rounds each , several times) using the Armasight 640 3-24x75mm (from Big Red Dog). The ammo American Eagle 115grn, target was a 1/2" plywood board shooting at a 2" square piece of reynolds wrap foil stapled on corners. Then shot a metal target out at near 200 yards and it was shooting about 6 to 8" low.

Went from 556 to 300BO to 6.8SPC now migrating towards 6.5 Grendel.

Well hats off to ******** from Third Coast, he messaged me and offered to send me a thermal zero target for free.

What Todd mentioned is what I'm hoping is the reason for the larger groups. I will report back next week after I use the thermal target.

Again, thanks for all the input.

My go to targets are using "muffler tape". It is the bright silver aluminum tape used for heat resistance. In fact,I believe that I first heard about it from TLM or someone else here.
It comes on a roll. The back side is extremely sticky. It is about 3 inches wide. I cut it into about 1.5" squares and put three pieces together. Using three,they seem to reflect the suns heat and stand out better on a piece of black poster paper that has heated up in the direct sunlight.I can easily see these at 100yds with my thermal.
Thermal (firearm) accuracy. - - -> I can easily "walk" my thermals zero over to the tape and after the final adjustments can put three shots into the tape squares at 50yds. This,during daylight hours. I never attempt to zero my thermal in the dark. It's a real PITA. --- pruhdlr

I went through this thinking as well initially. With my day glass I shoot ~1.5MOA with crappy PMC Bronze and just under 1MOA with 150g Hornady American Whitetail. My Pulsar only does 1MOA adjustments so I knew it was only going to get so tight, but once I found out where we are the average night hogging shot is well under 100 yards it was not anything that concerned me. I'd say half the time it's under 50 yards for us can't figure that one out b/c we don't wear camo, don't worry about scent none of that our hogs just go full stupid at night when they are out in the fields chowing. I read a thread on here suggesting aluminum foil tape and that did help me to get it a bit tighter with 1" squares.

Not everyone is shooting mags empty at running hogs, I'd like to know the most precise thermal for predator calling and head shots. I've seen an IR Hunter that changed POI with zoom level, would be nice to know if the new releases are any better.

Then find a precision thermal forum. Good luck.

Are you using a .22 or something?
