Default M&P 15 22 extraction probes may be entire bolt carrier group

I mean we all bustin our chops to fix this dang thing by replacing the extraction pin,,,looked at mine not replaced yet,,it looked fine still a fine sharp point I've barely taken in my back yard more fewer than 4 times max I've put thru it 2 magazines,,however I did buy used but in excellent shape not a scratch ,,not in box,,so what are odds it's why ol smith and Wesson both ain't sayn nothing ,ain't trying to recall nothing specially if it's the entire bolt carrier group or does replacing the extraction pin seem to fix the issue,,will replace mine this weekend,,,,what kinda luck u have????

Default 2012 post stating 99% of m&p 15 22 extract problem is user error

I was like may be true in some cases but what about coming directly out of box first fires extraction problems?? I won't question someone's knowledge because their knowledge is a lot greater than mine for sure but my opinion yes smith and Wesson has a solid name but doesn't mean the are free from error,,,this was in 2012 too,,so also goes to say it's been a problem apparently,,still not rectified or completely fixed by smith and Wesson,,all I do kno is I'm gonna replace my extraction pin clean cavity really well,,,but ask me I think it might be kinda funky perhaps like I stated eariler may be the entire bolt carrier assembly,,which again my be why smith and wess ain't volunteering nothing,,it's a nice piece of small armory,,,tho all polymer but be that as it may,,it's aggravating every third shot extraction ejection problem did notice pin did pull it out back pin put another in the chamber spent shell hung around didn't fully kick out which might have somthing to do with the extraction positioning,,not a genius let me kno what y'all kno or thing

So what problems, exactly, are you having? In order to obtain assistance, you will need to state your problem clearly. Just ranting (incoherently) isn't going to solve anything.

There are several things which could lead to a Failure to Feed, Failure to Extract/Eject or Failure to Fire, for instance:

1) A broken firing pin. You indicated this is a used firearm. Perhaps the firing pin itself is broken.

2) The bolt carrier rails are slightly bent, or have a burr. This will impact the bolt, perhaps causing failure to eject/extract. It can also slow down the bolt carrier, resulting in a failure to feed.

3) Extractor needs replacing. As many have noted, for whatever reason, after market extractors tend to do a better job

4) The ejector is bent. The ejector is the small piece of metal with a hook that is attached to the barrel. Its job is to eject a casing that has been extracted out of the housing. If it is bent too far up, it will create resistance against the bolt and slow it down, causing issues similar to bent rails in (1). If it is bent too far down, it will not engage with the spent case, and can cause failure to eject.

A very concise and accurate description of the FTF/FTE issue which occurs in the 15-22. Well done Sithlord...this should become a feature in the 'Notable Thread Index' sticky.

A extraction problem may be as simple as a good scrubbing of the chamber/barrel with a cleaning rod. And I know for a fact that on the Ruger 10/22 and Victory 22 pistol that extraction problems arise if there's a buildup of carbon on the face of the bolt. Before anyone starts tugging & pulling on parts with a pair of pliers, Let's first field strip the poor thing and give it a good cleaning.

Most....issues I've seen with rimfires are the result of a lack of maintenance

I left off

5) Are you staggering your rounds in the magazine? This can lead to failure to feed issues as well. Newbies to the 15-22 often have this issue.

Most of the feeding problems I have seen on the 15-22's have been related to the ejector. The ejector needs to be as high as possible without rubbing on the bottom of the bolt and as close to the center rib as possible without rubbing. These ejectors are not heat treated to spring temper and will be bend relatively easily. I check mine reguarly and have to reposition it every 500 rounds or so since it seems to bend outward with use.
