so can you possibly convert to inches.. like with a caliper set to decimal? is it 1/2" by 20 threads?
so I don't know what the deal would be as far as shipping a moderator, but if make sure the threads are correct, how long the threads are.. and how long until the end of the air tube because you'll want the male threads past it.. I can make it out of brass and try to mail just the adapter unless you find out the moderator is ok to ship..I can make it out of Cold roll steel or it's faster and easier to use brass..
then I could mail it maybe as a gift, and if it works out you can mail what you think it's worth..at least enough to cover postage.. then you can put on whatever moderator you choose..
let me know if any of this sounds workable.. I can't imagine a terrif or anything wrong with just a small brass adapter the size of a small bolt..
I'd love to pass on the moderator but I assume that could easily make it complicated..
if I have to declare value, could just guess maybe $5 ? if you can't send anything it's fine..
just get me the dementions.. length of thread on the gun.. how much smooth area to pass the muzzle and then I'll make the make thread says the gun so you can use the same thread protector..
oh and I'll need the out diameter to clear the air tube..
I can make it all smooth or knurle it to match the knurling on the threaded end cap protector so it's easy to install and remove..
let me know what you want.. I don't think sending a small part the size of a small bolt should be a problem..
