Stepped Fluted Barrel

[kwintz]

Just recently aquired a new rig. It has a fluted barrel that is stepped, as in half of the barrel(1st half by the bolt) has a larger diameter than the second half. But consistent longditudinal fluting along the whole length. What's the benefit of having the stepped barrel?

Yeah, I would like to see a pic of this barrel myself.

No one gives any advice until pics are posted.

For some reason it only allows a URL link, i cant upload photo.

You need to upload it to photobucket or Flickr then link the pic... Accounts are free with them and quite secure.

The only reason I knew of to step a barrel was for a Reflex suppressor. Have to take down the barrel od to have the rearr portion of the suppressor slide over. Other then that I am at a loss other then aesthetics.

Like tapering the barrel, this would reduce muzzle heaviness, shift center of gravity to the rear, perhaps enhance balance, reduce weight.
Cylinders are easier to turn than tapers.
Apart from that, can't think of any functional reason.
Maybe it was done for the sake of a different look.
Can you track the rifle back to whoever made it, and ask?

definately puts the meat where you want it.. but it does look turned down for the muzzle brake contour

That looks very nice.... Gives me an idea...

Not a good idea when the stepped surface has flutes cut into it. It would damage the back end of the can.

Looking at that barrel it seems to be a way to reduce OD and weight without having to screw with tapering the barrel. It actually looks pretty good IMO.

Barrel has a "Jennings". Stamp, as to the exact history im still waiting for it... Cousin said it was full custom build with the builder now deceased, being his last build. There's an info package I'm waiting for that has all the specs, load info and history. Can't wait to actually spend some time and put a bunch of rounds through it.

Do you have any pictures of the full rifle? I'm sure many of us would love to see how the barrel completes the rest of the image!

I’m not trying to ne an a¬¬hole but personally I think it’s a manufacturing error. The lathe operator miss read his/her mic and adjusted the cross feed on the lathe too much. So not being a high tolerance OD and the barrel’s ID finished, the overall appearance looks fine plus leaves interpretation. The error was caught midway of the pass and then the decision was made to leave it. The time spent up to the point of the error cost too much to scrap knowing the end result would look and function as normal.

There is no way. With that depth of cut the barrel would vibrate like a son of a ##### durin the pass. That step took several passes to form meaning it was done on purpose.
