580 series
If you're satisfied with the accuracy and consistency, perhaps the first alteration I would consider is a smaller gas bushing along with re-torquing the gas block, also add a Wilson shock buffer. You can save money and down time by doing it yourself. Many here have used a 5/32" roll ground to proper length and inserted inside the existing factory bushing. Re-torque the gas block screws to 35 in.lbs. making sure the gas block halves are even on both sides. An improvement in accuracy is possible and you won't launch the empties into the next zip code. Good luck and enjoy!
