Hi,

The cast majority our customers have less than 3 clicks of adjustments (ie, less than about 0.75 to 1 moa) going from unsuppressed to suppressed. In most cases, the poi change is due to deflection of the barrel: a stiffer barrel will have less change. However, in the remaining minority of cases, we've noticed that the rifles have a larger shift. This is usually due to one or more of the following: thin barrel, weird harmonics, additional forces on barrel that affect dynamics (e.g. gas guns), or some other rifle "build" issue. A shoulder that is not cut exactly square or threads that are not concentric to the bore could also cause it.

In the end, if you look through the breech and the suppressor looks centered and you're not getting baffle strikes, and it's repeatable and accurate, I would recommend to just shoot it.

hope this helps
Zak
