First, when you call for service, be polite. If you are not polite to my staff, I guaranty you will not have a pleasant experience. Remember the old saying, "You can attract more files with honey that with vinegar." If you call with an attitude, my staff has been instructed to put you on the back burner. If you are nice and polite, you will get quicker service.
Second, please read the manual carefully. I know it's boring but there's important information there. Many people do not understand that you need to set the gas correctly for function and durability. It's really quite simple - put it on the setting that throws the brass 8 to 15 feet from the rifle for any given ammo. Do not just leave the gas system on the highest setting, If you do, for some ammo it will kick like hell, throw your brass 40 feet, give you trigger slap, and damage your recoil buffer (a cheap part).
Third, please send us the following information: ...
A complete description of the problem, BE BRIEF. If you write and essay about your vast knowledge of firearms base on your long time relationship with your AR-15, we won't read it.
Fourth, if you post a bunch of whiny petty negative stuff here or anywhere, I guaranty very slow service. I have made that a policy. Yes, we've made lots of mistakes with service but that is behind us.
