OK suppressor guru`s, question

[erkinator 2]

Who has had, or not had issues with suppressor causing you to resight in your rifle???

Watched an episode of pigman last night and he had big issue when he mounted one on his person hunting weapon. I had not heard of this before,but then again. I`m a novice

Some have a minimum POI shift but repeatable. I mainly shoot 25 to 50 yds un-noticed using CCI SV 22 I'm gonna stretch it out in Macon with HV rds
I'm putting the 556K on the AR this week so I'll be ready for the Macon M&G to test it out past 100 yds.

Do some googling about POI shift. There are many factors that can make this happen and its common. when you attach the suppressor it changes barrel harmonics, add weight to the barrel, and swirls gas really quickly around the bullet. This can change the point of impact but as mentioned it should be "repeatable".

Pretty much this. You'll have to see what your can does. I sight my rifles with a can mounted so it's not really an issue for me.

Thanks all for the info

10/22 with a Zephyr XL has very minor shift toward the lower left (if I'm remembering that right- I haven't changed it since zeroing with the can and CCI subs)

AR with the specwar shifted about 6" low at 100 yards... big change. Always the same shift though. This is one of the reasons I need to switch that rifle back to a carry handle type rear sight- I need elevation adjustment. My Troy sights don't have rear elevation adjustment- I have to screw the front post in/out for that (Pain in the ass).

Rem 700 in .308 with a Deception, very little change. Really no change essentially. Maybe I just got lucky with that one.
