PABuck, yeh Im gonna use them for mine, you probably will be fine without them, but I chose to use them. they are only a few bucks for a dozen. I don't even know if you need them for the FMJ. They only weigh 2 gr so it's no issue with extra weight.
I choose to use them on the Axis series shafts also. IMO it's a little better even if it is not absolutely necessary.
Id rather the BAR take the pressure as the end of my shaft.
