The biggest problem with these guns is that they do not hold up as well when shooter errors occur.

Most common shooter error?..... improper/short seating of bullets and-or continuous broken pellets that slowly/gradually weaken steel wall. Strength issues also with bolt/plunger actions & breechplugs.

So if you are a new ML user that's clumsy, absent-minded, forgetful, lacks concentration... etc....buy a T/C,White, Savageor Knight instead.
