Hi guys and gals long time lurker here and have got a lot of great information here for my 15-22.

My 15-22 would stovepipe every second shot and in a 6 out of 10 shots. in the first 100 rounds I had about 60 FTE's so I adjusted the ejector but made little to no difference so I purchased the volquartzen extractor and installed in 2 minutes 700 rounds later NOT 1 FTE yes I said not 1 FTE after installing this extractor. This is a must install for this firearm.

To the original poster purchase this extractor and see if it fixes the problem first before shipping back to S&W and if you do ship it back switch the extractors back out. I wonder if Smith installs this when shipped back as they seem to fix the issue but nobody can notice anything changed with the firearm when they get it back and S&W will not comment on what they did.
