Here's a video I made with my iPhone shooting the SAS Reaper and Arbiter on my 16.5" 308 and 16" 5.56. The Arbiter is noticeably quieter, not sure if the sound in the video reflects that, but the reactions in the video should tell you how stark the difference in sound was. For reference, the Reaper sounds to me exactly the same as an AAC 762SDN-6, which it probably should considering their similar sizes. The Arbiter is in a class by itself for sound reduction though. The dealer stated that he found the Arbiter to be quieter than his dedicated Surefire on the 5.56. Anyway, I'm not a filmmaker but I hope the comparison helps anybody trying to decide between the two. I've got some pics of them side by side also to show the difference in length and all that, but I'll have to upload them later. The difference in weight is almost none.
