I have just gotten a SCAR 17 and it is much louder than my SCAR 16. I have used foam ear plugs shooting the 16, but they are not enough with the SCAR 17. My ears are ringing after a day on the range with the 17. My cheapo ear muffs don't work either when I push my cheek into the stock. What are you guys using for ear protection when shooting the SCAR 17?
