First time posting, long time reader. I just got a 16” barreled .308 The Fix by Q rifle. Went to sight it in with factory Hornady A-MAX ammo and was disappointed with the 1.25”-1.5” groups at 100 yards. I then attached my AAC Titan-Ti .338 suppressor on the gun and at 100 yards it shot 14” lower that the unsuppressed shots. Why such a huge POI shift? On my .338 Lapua there is no POI shift and with this .308 it’s huge. When using the same suppressor on my AR-10 there’s hardly any shift also. So confused...

Why such a huge point of impact shift with suppressor

16” barrel and not sure which manufacturer. It’s an early serial number under 300 and thin contour.
As far as accuracy some barrels need some rounds through them before they tighten up and it may not like that ammo. I'm reaching here but It sounds like something is off or out of alignment. Did you check the suppressor by bore sight or a rod to insure it's not rubbing? Although with a .338 can you should be able to throw your hat through it. Can you check it now to see if there are any witness marks inside?

Part of the issue is the size and weight of the Titan 338 Can, it's huge and heavy.
You are hanging a weight on the end of the barrel, so it drops a bit, 14" is big, most are not that crazy, I would try a different suppressor, and it does sound like it does not like the ammo.
How the barrel locks up to the receiver could be part of it on top of the contour. Usually, when it's that big a shift there are other things at work. Because it is a 338 Can you may not get a strike but it is acting like it is not centered right and wants to skip off the can.
I would first swap out the brake, those are usually the weakest link.
Suppressors are variables, you are adding more negative variables to the system when you include a suppressor.

This, several people all said this, that Titan is made for heavy profile barrels.
Do a typical break in process, then shoot different weight match rounds. Start with 168gr/175gr FGMM. You should see under 1” with that gun and more like 1/2”
I am no expert with like others are on here so, just my .02 listen to guys who know like Lowlight and other long range shooters.
I checked alignment and everything looks really good. No internal strikes or anything. It’s a QD mount suppressor and I’ve used it on many rifles with no issues.
I shot 3 different types of factory ammo, the best was Hornady A-MAX 168g and only 1.25-1.5” groups. I tried Hornady Match ammo BTHP 168g and that gave 2” groups. Also tried some Browning 155g ammo I had and that gave 3” groups. I messaged with the man himself (Kevin Brittingham) and he said to try Federal Gold Medal Match ammo. He said no gun leaves his factory without first shooting a sub 1” 5 shot group.
No worries, I’m a seasoned shooter and long time hunter (I shoot better than all of my friends too). I have many rifles that shoot 0.25” groups with me shooting them.
