MUZZLE DEVICES - WHY FEW OPEN CROWN DESIGNS?

[Edsel]

Most designs have this "dirt trap" that causes molten lead and hard carbon to permanently affix themselves to the crown.

By far the most common design.

Only a very few examples have an "open crown" approach, such as these.

While the crown does get dirty, it's relatively easy to clean with a cotton swab.

Anybody know the rationale for the former?

A muzzle break has to have several flat surfaces to apply the pressure to in order to counteract the recoil. An "open crown' as you say is just a muzzle device but not really a muzzle break.

Are you certain about that?

Your second statement makes absolutely no sense.

I do know how a brake works, and the two "open crown" examples I posted up there are fairly effective muzzle brakes.
