Thanks guys. This definitely seems to be the issue, as you point out. I'll check it out.
Thanks. You rule.They are the same.
Thanks. For the SCAR I plan to use a brake, actually, and FH for bolt guns.Yes using the SilencerCo shims you can time it on the SCAR barrel. However since you are using a flash hider I would just put it directly on and without shims and avoid the headache.
Awesome post and info. thanks!Yes, I took some pictures of it with my Saker 762 on my Scar 17 here: http://fnforum.net/forums/sbr-suppr...17-suppressor-concentricity-measurements.html
