[QUOTE="Ah1356, post: 1558191, member: 108701"] The POI shift is not really related to MV, at least not in the obvious way. The can is not causing the bullet to go slower and hit lower. In general the suppressor can add a little speed, so if velocity were the primary cause here it would hit higher. I haven’t studied it formally, but I think generally the difference is harmonics, and the direction of the shift can be up or down, left or right, depending on your barrel/suppressor/load. My suppressor is fairly heavy, and on a 26 inch barrel my 0.2 MIL POI shift down is pretty small. I don’t think your 2.5 MOA shift is surprisingly large, especially for a carbon barrel, which I suspect is not terribly stiff. So long as the shift is consistent, just account for it and you’re good to go. [/QUOTE]
