    What length of thread is required for Huntertown Arms .22 RF Guardian?

    I noted that the standard length offered by High Desert Dog for a 10/22 barrel is 0.400" with other lengths being optional.
    I'm not sure now what ADDCO listed, if they even did.
    And I have a Savage Mark II FS-VR enroute which I don't know what length of threads it has.

    I emailed Huntertown Arms several days back but have not received a reply.
    I'm not slamming Huntertown. For all I know they didn't receive the email. Or they are swamped to the point that they can't get to it yet. Stuff happens.

    Thanks in advance.

    .400 is the standard for most 22lr silencers, Savage threads theirs too long, I think about .600 give or take a few like M16/AR15's

    I appreciate the input.
    It sounds like I'll have to work something out with Savage. A spacer maybe, or just shorten the threads. When it arrives I'll measure the thread length.
    Thanks again.

    My MKII FV-SR is threaded .475 long. It's a little longer than normal, but not too long where you need a spacer. If you want to be pickey, an AR15 peel washer is .075 long and works perfectly on my FV-SR to make thread length exactly .400 long.

    That's good to know. Thank you.
    When the gun comes in this week I'll get some measurements and in the meantime be looking for a source of peel washers. I need to order a few small AR parts anyway.
