can anyone post a picture of the business end of a fake 607 Moderator?
is it little bitty (.250"ish) or great big?

i found this in my dirty clothes,



and after some saw work, i had this,



and here it is mocked up.



what's the I.D. of others?

Looks good. They are same diameter as the Xm177 moderator AFAIK.

That one looks a little fatter or bigger than the usual ones. Here's one I slightly modified.

Here is the business end on mine.

Bricks and my65pan made ones are itty bitty. Never saw the business end of a real one.

There was a member who posted museum pics of a real 607 some years back, but I don't recall what the end looked like either.

IIRC,that was member 101airborne or something like that. Stoner has a bunch of his pics saved.Calling Mr.Lou!!!!!

Here are a couple I have collected. The first one is from a museum and the second I believe is from Stoner and did not have the finish yet.

Here's the business end of mine.  I'll look through my pics  and see if I can find the posted pics from 101ABN327, although I do not recall the museum piece having a moderator on it.
EDIT:  Hey, 101's museum pics did show a moderator, although the pics did not show the business end of it. Pic is posted at bottom of post.


John Thomas also posted a few pics of a 607/with mod that was on display at the Rock Island museum, if I'm not mistaking. His pics also did not show the business end. The pic of the end of mine was said by WATom to be very much like the one that he personally examined in a museum. I forget the name of the museum, although I believe it to be the one that held the 607 that he "blueprinted" to get the stock dimensions prior to his production of said stocks.

Braceman manufactured my faux 607 moderator.  It has a smaller hole...large enough for a .22LR and 5.56 to pass through without any problems.


Size comparison to one of Brick's XM moderators


Close-ups of the hole diameter with a 5.56 round and 22LR.  It swallows the entire 22LR up to the rim.












Picture of my dedicated 22LR 607 style build.  Went with the longer barrel to avoid the tax stamp issue.

You will notice in the museum pic that 5457 posted that the hole in the end looks very large. The large hole is a counterbore, with a smaller though hole. (not visible in the pic, but verified by WATom)

thanks guys, so much for using what was in hand.

This is the best photo I've seen of a real-deal (photo credit to Springfield Armory):


You can see the inner bore is small, then it has a larger opening at the end, but the end's larger bore is just the last 1/4" or so.

Braceman made mine also, I asked him to open the end up like the
Cone on a 608,, not sure what my reason was at the time,,,, but I like it
