    1 size fits all I shot .25 through mine although they do sell a specific .25 cal mod.
    the bore is 7mm as in it takes a 7mm hex key to unscrew the face plate.

    The BSA VC (variable choke) moderator has different collars for each caliber. As a moddy, it stacks up quite well to the HW, but it does depend on the gun. It is quieter on some guns than the HW, and louder on others. I don't know the science behind it but that's my experience.
    Good deals with these members

    The clearance hole is about 7mm so no issues with up to .22. The .25 is 6.35mm so it is best to get the .25 specific moderator.

    The VC and the HW have similar internals but the VC has plastic baffle washers and in a old article in airgun shooter the VC was quieter using a Sound Level Meter, so perhaps one of yours has plastic baffles

    Doesn't the VC have caliber specific end plugs to restrict the outward flow of air? I have no idea if they are any quieter than an HW but when I put the HW on my R10 Mkii all I hear is the action and a puff of air coming out of the barrel. Any quieter and I might have to really check to see if the gun had fired.

    Yes .177-.25
    The only way you can say that one silencer is quiter than another is by using a Sound Level Meter because individuals hear sounds different

    Venting out the first chamber with added padding does make a noticeable difference when you measure the dB levels in front of the gun. Other than that you can tune the dB peak to higher or lower frequency. Shrink tubing the silencer is also beneficial.

    Did you buy them new or used ? if used someone might have modified/buggered up one of them, I bought a used A&M that had been played with & was rubbish, sent it back to them & now it's fantastic.

    The internal washers are also 7mm bore so if using .177 you could go a bit smaller which (in theory) should quiet it a bit more.

    not much inside at all really , baffles on both HW mods are like plastic hair curlers , with little bit of felt.
    is that it ???
    maybe more felt might help
