As I recall, the db suppression was actually very ordinary compared to a number of other units on the market. The ability to replace the SRM module certainly looked like a good thing, but I don't think the market really embraced the unit. I was very seriously interested and watched every video available at the time and read every article that I could. I think the OSS was really targeted at full-auto usage where all of its virtues would really come into play. Without full auto, I don't really see the unit as being exceptional.
