as much as I love these rifles, I was a little bummed to find that the drop arm spring on my varmint no longer works. I noticed it today when I was cleaning it. I emailed mossberg in hopes that they will just send me a new spring. I really don't want to send the rifle in, I figure the warrantee was void after I installed the tactical bolt knob anyways. If they insist I send it in , I am going to take it apart myself and try to find a spring on my own to fix it. I would rather not pay for shipping and their gunsmith fees to replace it.
