    Zak, I tried a search and couldn't find info. I have an ultra 7 30 cal which I LOVE! I am getting an ultra 9 and am thinking an 223 ultra 7 for 204R, 223, etc.
    I know ultra 7 and 9 are good on 204/223, but I really don't like having to change them too often.
    Question - is the ultra 7 223 quieter than the ultra 9 on these smaller calibers?

    They will be very close, typically within about 1 dB

    What thread adapter would you recommend with your suppressors going 1/2x28 to 5/8x24 to use the 30 ultra 9 on a 223 rifle?
