If you do not contact Shilen about the problem, they cannot even make an attempt to remedy the situation. They are very reputable and my interactions with Shilen have been first rate.I'm not sure they would. If it is likely any other company, they will find a reason that it isn't their products fault....bad installation, user error, yada yada yada.
Even if they did, what are they going to do for me?...they won't have any barrels available until early '27 or so. At my age, I might be dead by then.
If there is no effort on your part, then you shouldn’t even comment on their potential response.
