The one concern with suppressing the Ruger GSR is that your suppressor (or mount if your suppressor uses one) is not indexing on the barrel shoulder, it indexes on the front sight (which is pressed and pinned on the barrel behind the threads).
The concern is that the front sight base may not be square thus causing the can to pull to one side or the other when tightened and increasing the chances of a baffle/endcap strike.
Check with the manufacturer of the suppressor you intend to use and see if they have any guidance with respect to using their can on the GSR.
