    22 Barrel and Suppressor Project

    Gidday Guys

    I feel the need for a 22RF build. I have an action. I have an idea. Oh lordy help me !!

    So an ideal barrel length for a 22 can be pretty short, say about 10-12 inches. If its going to be real short it could be a quite heavy or a bull barrel. If the suppressor was integral or machined into the end of the barrel then the short effective length wouldn't be a problem with the law would it ??

    I have in mind the design of a Manatis suppressor, the design is very simple to machine, basically what I'm proposing is to counterbore the muzzle end of a heavy barrel, machine in the suppressor shape and then make up a cover to bring it back to its original diameter and a finished appearance on an overall length of about 16 inches.

    The balance should work out quite nice, it would feel stable in the hand, but would be lighter than a full target barrel . . . the ideal might be to get a suitable aluminium sleeved barrel I suppose but I'm not going to hack up the Kidd one I have as an experiment !!

    Anyone know if this has been tried ??

    I know someone who had a extra heavy blank turned into a barrel/suppressor unit-alloy sleeve screws on by the chamber and then a cap on the end that attaches to the barrel to try and tension the whole thing. Each baffle has a o ring around it to seal the gap-these often come off when trying to assemble.

    It cost him a fortune!

    It's louder to my ear than a pistol with the same length barrel and a gun works .22mag can.
    But,it's short and legal. And very cool.

    As your going to be limited by blank diameter as to your baffle size(unless you get extra funky) I would try and maximise the internal volume to boost performance.

    I love short guns so have been tempted to get something similar made but the cost puts me off.

    Talked to a gunsmith about it once and he thought that if a run for made up for the 10/22 and the cost could be got down that they would sell well-but at that time he was a one man band with no time for new speculative projects and I couldn't justify the $ for a one off.

    Sig have done something along these lines for 9mm.

    This is a little different to what you describe, but its what I've done to my 10/22.
    Photos are my first attempt - second attempt is shorter but same design.
    Looks good, doesn't catch on anything, keeps that full heavy barrel look

    how deep would you counter bore and what then would you use to cut the crown? reamer?

    For the crown you'd probably just finish it by hand with a ball and cutting compound -the counterbore would be about 100 mm

    Gerbs - yep we're on the same page - is that a aluminium sleeved barrel (like a Kidd etc) that you've used ?? How short was the barrel on the second attempt ??

    Thanks

    Aluminum tube from Ulrich aluminum in Palmy (where I live), Maniatis suppressor, and I think the barrel ended up at 11in.
    It JUST cleared the stock, and overall (without suppressor) length was 765mm.
