They fix a problem when confronted with one ... then appear to go back to business as usual until need to address an issue arising again.

As to a MATCH grade barrel from the factory ( LW logical choice ) they do so for a few select pistol models already. Rifles in .177 & .22 cal never heard of it happening so far
