I'm new to the hobby and searched the best I could, to no avail. I have a line on an older R9, pre muzzle brake, at a price about $100 less than a new one from PA or AD. Looks to be in great condition and owner says is was not shot much. So are the older ones better or should I go with the muzzle brake no sights new version? Also, what year did they convert. Thanks in advance. CV
The cocking shoe is a big improvement, but you can do a lot worse than any version of R9!
