Suppressed in SD,
I have had an OSS for several months now and really like it. if you look at the posts I've made you can see all the info I've put on these forums about the OSS so far.
It hasn't been a lot of info. I did post some pics of the POI change the OSS made. I have also made a few other comments.
The biggest things I've noticed so far are the OSS looks like a monster sized can but really isn't . It only extends your gun length buy about 3-4 inches. Most of the can sets back behind the end of the barrel and seems to help give you abit better balance. The back pressure is very minimal. Most suppressors make your unfired casings in you AR mags black from the gases. They stay pretty clean when I fire my OSS due to the minimal gas back pressure. The sound reduction is also very good.
