I bought this selector along with the other M16 FCG parts offered by KS. I have not installed any of the parts yet, but every one of them including this selector arrived in brand new condition & you can def tell they are well made, quality parts. Glad I was able to get ahold of the other parts before they were all gone. If KS gets them in stock again, don't hesitate to jump on em cause they will go fast
Good selector
Review by
Military grade selector. Mine looked new with no wear marks. Installed in a semi-auto build along with the M-16 trigger and disconnect. Worked OK with a semi-auto disconnect and trigger, but not really the best. With the M-16 parts all went very well. Unless you're using the auto sear (NFA rules apply with that), don't put the selector to where the "auto" fire is. You won't get automatic fire, and if the rifle does fire the timing will be off and the bolt not in battery. Not good! But "safe" is solid and "semi" is clean and positive.
