All barrels are crowned. Not all have a recessed crown. Most barrels have a radius crown and a few have a flat crown with a slight bevel that you almost can't see.

that's not a "custom"'s an Elite II..

here's crown 4.7" barrel. guess if it's good enough for $2500 nighthawks like someone mentioned, it's good enough for me.

Default Okay, Missileman

As well noted by MasterPsmith and the Midwesterner, crowns appear on nearly all firearms. Crowning is simply turning the muzzle so it is square to the axis of the bore. The idea is to give the bullet an even 'departure' from the bore.

To add to the confusion, many barrels are crowned 'flat' and seem to be simply cut off square. Looking closely, one finds the flat part has been trimmed with a fine cutter, and or polished.

Older revolvers and rifles have a radius crown - noted by Master Smith. It is visible to the naked eye.

The treatment you describe is a 'recessed crown' (for obvious reasons) and the idea is this makes difficult the accidental blow to the actual crown, which can disrupt accuracy.

My apologies if I sounded snippy.
Finally back in the United States!

No offense taken--it's good to hear some advice and opinions from people who are smarter than me on this issue--that's why I log in to this forum. Thanks, and Happy Near Year!

Default patchworm

Ok, I know it might be difficult to understand but like the op said, water will wear down granite and a soft brass brush will wear down hardend steel with enough time. Use a bore guide when you gotta use a brass brush.

When you do not need a brass brush, use a patchworm. when you need something stronger then a patchworm, use a nylon brush (with a bore guide when possible).
