Gunsmithing Barrel threading not flush with the crown?

[USNavy06]

Hey guys quick question. I picked up a barrel second hand and had questions on the barrel threading.

The crown is recessed and the threads are forward from the crown. I’ve never seen a barrel like this and was wondering if I should just chop this thread extension off and thread at the crown.

This will be used with a suppressor. It’s also a Lothar walther rim x .22 barrel if that matters.

Let me know if this is good to go. Thanks!

Maybe there’s some rimfire voodoo I’m not aware of but that doesn’t look right to me.

A few do it that way, Anschutz does for one--at least on some. It's to prevent the threading from impacting the bore diameter....

It's typically a good thing...more operations, machine time, and cost. Shoot it, see how it does.

Sounds good I just didn’t want to blow up my suppressor haha. Just haven’t seen threads like that before.

Right....but just like any other second hand ( or new) barrel you are putting a suppressor on, check it.

I.e alignment rod, look down the bore with the can on, a few into paper to be sure they are not doing something squirrelly, etc.

ANY barrel can have issues.

Good luck,

That’s how a proper rimfire thread should be imo. Keeps it protected and keeps it from flaring the bore choke.

Thanks. I’m just getting into the rimfire world so I wasn’t use to seeing muzzle threads like that.

This is exactly how RF treads should be cut, although the diameter of the counterbore is comically large it accomplishes the same goal
