About a month ago I called S&W because the mag. that came with my 15-22 was doing the mag snag thing. I was told to send in the mag for inspection which I did. I then went and bought three additional mags and I began experiencing the same issues with them. I called again and was told to send in the rifle and the three new mags which I also did 13 days ago.
On Wed. Fed EX came with two of the new style mags to replace the first one I had sent in and today he brought my rifle with new springs in place and three new replacement mags.
My rifle was at S&W for three business days before they had it on its way back to me.
Outstanding service from the moment I called and dealt with extremely polite and helpful customer reps. to their treatment of my problem.
I just put 200 rounds down range with nary a burp. I'm a happy camper.
