    I know air gunners are pretty creative. Let's see what you come up with. I have limited mechanical skills, so no mills, lathes or cnc machines. I'd like to see you from the cheapest of the cheap to the ones that cost more than the a.g. itself. I'll post mine up when it is completed.

    Well OK, I'll bite.

    I have not finished the work.  It has not even been shot once.  Perhaps tomorrow, weather permitting.

    The finished unit will have a side wall of carbon fiber (if I decide the weight savings are worth it).  At this time it is PVC water pressure pipe.  Strength is not the issue, weight is the issue.  This thing weighs about five or maybe six ounces, which can be trimmed some by changing the baffle design.

    ID is 38mm

    OD is 42.5mm

    Functional length inside is 120mm

    OAL is 150mm

    Internal volume empty is about 12 cu. in.

    There are 5 baffles, each 20mm tall inside.

    There is an expansion chamber at the barrel end which is about 1.5 cu in.

    The baffles are stacked against the muzzle end end cap.

    There is a 1/2 x 20 UNF nut embedded in the end cap to attach to a rifle.  I can print that cap so that the nut is not exposed.  This will do for prototyping.

    A touch of flat black paint should improve the appearance of the device but I won't need to do that till I've tested it.  Who knows how bad it might be clipping?

    That is way cool! Thanks for sharing!

    Have rules changed? I thought discussing the construction and design of moderators was prohibited, but I see several threads in here and at least one of them was moved by a mod/admin to this new section.

    I believe you are confusing this forum with another outdated forum which had all sorts of censorship policies and rules.  I could be wrong, I suppose.  You could flag the thread and run it past a moderator.    😉

    They seem to know the posts are here, no need to flag anything. I'll just read and store info.
