I get the impression that many people who either consider buying or do buy a suppressor have little idea as to how a suppressor will affect rifle performance. I certainly have/had no idea as to how loud one will sound, how much it might affect POA/POI, how much it will affect group size, what I might see in POI shift when I remove and reattach the suppressor, etc. Many seem to focus only on dB with numerous YouTube channels dedicated to suppressor reviews that address sound, attachment, dimensions etc., but few that address the other important variables. Of the three rifle suppressors I have I've only used one so far, and only on one rifle, so my experience is limited. I have two more rifle suppressors on order so hope to add to this thread over the months with my personal experience. With that in mind I'm hoping that some "scientific" data might help members here have a better idea of what to expect. dB data is hard to obtain and virtually meaningless unless the test conditions are the same but the variables below are generally much easier to obtain and quantify. If I obtain more data for a specific configuration I will update the data in a post if I'm still able to edit. If not, I'll start a new post that references the original configuration. Finally, I have no dog in this race. I will NEVER "massage" the data to make a suppressor or rifle appear to be better than they are so let the chips fall where they may. I look forward to seeing data from others to help me make an informed decision in the future. I'm in the process of obtaining my FFL and SOT so that I can sell and manufacture suppressors and I have no financial stake in any brand.
