POI Shift on cold bore shot

What causes the cold-bore shot to shift when shooting a suppressor? I've been having trouble with my silencerco Omega shifting about 8 inches high and left on my cold bore shot at a 100 yards on my AR-15, yet when I shoot it on my bolt actions it doesn't move it all

man, i do not know the answer to the question. but i do know that can would not be on that ar15 if it was mine. be worthless to me.

hope you can get some answers and get it worked out.

8 inches is extreme. Something, I don't know what, wish I did, but something is ALL jacked up.

I don't have much experience with the machine guns. But if that were a bolt gun, I'd be positive it was scope or mounts. Nothing else on a bolt gun could be capable of causing an 8" shot to shot shift.

Probably not anything else on an AR that could either?

I'm going to try to pull the suppressor off and shoot again sometime this week and make sure it doesn't do it without the suppressor

I had an old Gemtech HVT, that did the same thing, one flier on a cold can, the rest would be in the same hole, or really really close, I concluded it was the keyhole baffle design with none being staggered. I don't have time for that, so it's been long gone... I'm unfamiliar with the Omega, but when a company claims its the quietest can on the market, I usually sit back and take things into perspective first, and purchase later.
 
Yeah if it did it on guns other than this AR it would bother me but truthfully it's just this one gun I don't really think it's anything contributed to the suppressor design I'll do some more research and shooting and see if I can narrow it down to what it is
 
i just assumed you had owned and shot the rifle before canning it and therefore knew it did not throw the cold bore shot without the can. what is it they say about assuming? lol

I agree. You need to isolate the problem. Try the upper without the can and see what it does. If it cold bores fine, then I would say that Skinney might have been on to something.

But given that the can shoots fine off of other rifles, I might look at the mount between the can and barrel as a possible issue. Keep in mind that some cans pop pretty loud on the first round when the oxygen gets used up, so that could cause a harmonic issue. Just not sure why it would show up on that particular rifle and not others, except the mount for the suppressor.

Please keep us posted and let's see if we can put our heads together.
 
The fact it's tossing that shot out by 8 inches eliminates most possibilities. There just aren't very many ways it is possible to have a shot go 8 inches out of the group.

Eight inches out is not a "cold bore" issue.

If FRP is throwing a shot 8 inches I'll eat a coyote.

Mount... Not impossible I guess. But 8 inches, that is baffle strike territory. I can't think of any possible way the mount consistently throws only the first shot - and more importantly, throws it EIGHT freaking inches. That, is an insanely big number.

Don't know how a scope, or scope mount, only does that on the first shot and only the first shot either though. But I can't think of anything else, on any rifle, capable of throwing a shot off by such an incredibly huge amount, other than the sighting system.

Taking for granted of course that bullets are stabilized and no baffle strikes and all that happy kinda crap.

I'm kinda betting it's not only on the first shot? The 8 inch number is just too huge. Something is way loose/jacked up to throw a shot out that far and if so, it's not going to be on just a first cold bore shot. That might be the only time it's been noticed so far, but something that out of whack is going to show itself more than that.

Well I did some more shooting. I figured out what the problem is it was my scope is bad. Put a different scope on there and everything is dead on perfect.
