Hi Bob,

The end of the barrel is usually called the end of the barrel..

The "crown", to be exact - is the chamfer degree from the end of the actual bore/rifling to the highest point on the end of the barrel. Many use these terms incorrectly and interchangeably - but they, indeed are different.

To be exact - the barrel crown is concentric to the bore, so that all points of the bullet exit the barrel at exactly the same time with the same degree of deflection at its exact moment of exit. If the crown, at its points, is "off" or "dinged", the bullet, at exit - is deflected inaccurately. For example - many 1911 barrels are re-cut and re-crowned at 45 degrees, based on the bore and rifling, and its expected use.

In short - the crown only has to encompass the end of the "bore" overall (including the rifling) diameter - and has nothing to do with the muzzle end (which is larger - and protects the "crown") and the crown ties into at it's highest point. That "end point" or the entire end of the barrel - isn't really the "crown", if you see what I mean???..

So - anyway, back on topic - the end of your barrel on your HK can be blued or polished (or shades, depending on the factory process) - and still be correct as noted..

The "crown" can be either as well, as still be correct. These two features do speak to how HKs were manufactured, again - IMHO....

Hope this helps....!
