I bought this gun back in November and posted a few pics in the "last gun" thread. I knew about the recall when I bought the gun. It is an old recall, goes back to the 1990's I think. I am not sure how serious it is, I haven't been able to find anything dramatic posted on the internet. I tore the gun down and did have the old firing pin. It looked fine to me and I was going to hunt with it early in December but the trip got cancelled. There is plenty about the recall on the internet but here are my experiences. Winchester is still honoring the recall. (as of Jan, 2018) I called the 800 number (800-852-5734) and gave the lady my serial number. She confirmed it had not had the part exchanged and asked me to mail in the old firing pin. About three weeks later, I got an envelope from Winchester with a new firing pin and a new bolt sleeve locking pin. In another envelope, I got a check for $30 to cover the gunsmithing. I put the gun back together and have to go to the range soon. (it is 16 degrees today) We'll see how it goes. It should be fine.
If anyone has one, the old pin is just a round firing pin, turned on a lathe or whatever. The new pin has a flat section on the forward part. It slides thru the bolt sleeve locking pin so that part was also replaced.
I did see on the internet that a lot of people have had problems with taking these guns apart and putting back together. I have done it twice, found a couple problem areas. First thing that bothered me was assembling the bolt. It didn't look like the new firing pin protruded from the bolt face, until I realized that it did when rotated to the locking position. Second was putting the trigger assembly back. First way I did it was with the recoil spring in place. Got it done but it was a pain. Second time, I put the trigger assembly in place, pinned it, then put the recoil springs (2) and the guide rod back and it was not a big deal. Also remember that the bolt and op rod have to be all the way back to get the action out of the stock. I think it gets easier after you do it a few times.
I have some pics, the old firing pin is on brown cardboard, the new one is on blue.
Hope this is helpful if anyone has has one of these.
