RE: Warped ARF Stab- How to fix it?
Overdue Update- After trying all the ideas above (and more than once) I ended up calling Sig, explained the situation, and they replaced the warped stab. I can't say enough about how relieved and refreshing it was to find out that after all these years Sig remains the great company it's always been by practicing great customer service. Let's hope they get enough of our business to avoid the path to non-existance that so many other kit manufacturers have gone.
