I was sent 2 Ruger M77 MK 2 springs by mistake. Eventually I got the correct springs for my Ruger.  These springs lighten the trigger pull from the stock 4.5lb to 3-3.5lb range.  They're from Ernie the gunsmith in AZ.  Only one spring needed per rifle.  Just don't need them.  I won't respond to questions about shipping or emails that say "do you still have this item". I can tell if it's a spam email.
