Volquartsen sells a lot of Ruger MKI-II-III & MKIV’s, the Upper or barrel is made from aluminum with a 22 sleeve. How does the breech end hold up from the bolt slamming into it over time? I’m sure these are used in bullseye and one year a lot of ammunition goes down the barrel. Volquartsen has a great reputation for accuracy and I hear no negative on how well the barrels hold up.
Thinking of a Mamba Barrel for my MKIV, don’t want to spend the money if the barrels don’t hold up. Larry
