HK Cleaning Gear

The chamber face area of HK-91 style rifles is a bear to clean. There's a factory chamber face brush available, but it has stainless steel brushes, so I'm a bit leery. HKParts sells the factory brush for $25.

There's also a U.S. manufacturer, E&L Manufacturing, of a similar brush. The clone chamber face brush plus the receiver cleaning brush and rod cost the same as the factory brush itself. Hard to tell what the relative quality is without having both, however. E&L has a brass catcher for the HK-91, although it's unclear whether that will function with a port buffer and claw mount.
