I am running supurlative arms piston systems on 2 of my rifle length ars. Takes a little patience learning the system but in the end I would not look back. I found it was necessary to go to an adjustable buffer weight in order for it to cycle properly.It is much cleaner system and accuracy was not an issue.The buffer system will really do wonders on recoil
.Supurlative is all so an adjustable gas block that is needed if you run suppressed. Be cautious of what your inside hand guard measures as some handguards will not work. I really recommend supurlatives systems.
Good Luck Rick
Thanks for taking the time to comment and your real world experience. As I said I'm running suppressed all the time so I'm simply wanting something that runs cleaner AND won't be detrimental to accuracy. I'd rather have a dirty, accurate rifle than a clean one that doesn't shoot!
What barrel lengths are you running and average group sizes?? Did you notice any difference in accuracy after installing or have they always been piston guns??
