I just bought a Black Diamond XR last season. It was my first ML and I' m pretty pleased with it. Its not hard to clean, but I did have a problem once with the breach plug freezing after a bunch of shots with Triple 7. My biggest gripe is that the ramrod tends to rattle, but something wedged between the barrel and rod prevent that from happening. I keep thinking that the omega might have been a better choice though, mainly from hearing everyone' s great reviews.
