S&W MP15-22

[foothillman]

Oh I agree. I absolutely love the weight and profile of it.

I am just hoping to work out the issues with this little plinker. I took some footage. I only got one flawless 10 round mag through it.

Yea...that would drive me nuts.
Have no idea if a non issue but holding the magazine could be cocking it during recoil/feeding.
I would hope the small amount of movement does not affect reliability.
Some people had issue with 10/22 magazine movement causing problems.


Hope it get resolved soon......

I agree I’ve built more than a few AR’s, currently have 7. I don’t want to waste time or money building what’s basically a toy, just a plinker 22lr. When I can buy one complete that runs great for under $500, it’s a no brainer.

[AR22]

I have put together many AR22s using CMMG Bolts.. Most at well under 500.00 if you shop wisely.. I do not care what anyone says.. Those SW will NOT stand the test of time.. I do not mean 5 years..I mean a real test of time..

I keep seeing people say the SW is reliable.. I have also seen many claim the opposite... Stormvet..What exactly is the problem you have with functioning in your assembled AR22s? Mine all run 100% and you cannot beat that record.. And they do have a plastic receiver.. I do not care what people say about the greatness of those plastic Firearms.. The makers did not come up with all this plastic crap to help us.. They did it for themselves.


But to each his own..If a cheaper gun keeps more buyers interested in the hobby..Great.. I myself just prefer to have a little higher quality in my stuff....

It choked on basically all ammo I brought, even CCI had some hang ups. I brought SK semi auto, Blazer, Federal Champion, CCI (various packs).

So far the most reliable 22 plinksters I own are the HK416-22 and the Ruger 10/22 (old model), they'll eat anything.

I'll swap out the extractor and see if it does anything. From what i've seen on Youtube, it does help a lot.

Where are you located?
If you come down to my range, On Target, let's just trade bolts.
You could run your bolt in my upper.
and I could run your bolt in my upper
I know what ammo works in mine.

Either way, we will get you an answer.

I will support the rifle, standing, with my palm holding or supporting the 10 rd magazine and do not have issues, with most ammo.
As I have said, mine chokes on Federal Automatch.
In fact, mine does not like plain lead bullets. The must be plated, or I will have issues.
The only conflict, so far, it hates ANY Remington rimfire ammo, especially, Golden Bullets.

Years ago, I was vacillating between the S&W and a SIG 522, and decided to get the Sig, the only other semi auto .22 other than my 10/22s (including Kidd). It has been flawless, 100% reliable feeding, and other than the occasional bad .22LR round, operates like clock work. Just took it out two weeks ago and shot 200 rds of Mini Mags thru it, an extremely fun plinker. No regrets.

I have zero functioning problems with the AR?s I?ve built, they are all 5.56. I just don?t care to build 22 lr. I consider 22lr to be a plinker and a toy more then a serious rifle and just don?t want to put the time or money into a toy.

I bought an M&P15-22 about 6 years ago when my oldest boy was about 9 years old. It's unbelievable how much fun him and his brother have had with it at the range. Younger shooters or people that have a hard time picking up heavy rifles just love them. They are light and adjustable to smaller stature shooters. It's been very reliable after thousands of rounds. I have had people comment on it after range sessions. I run mostly CCI through it. I even have the CCI AR Tactical stuff thats made for it though I can't tell any difference between that and just regular mini-mags. Fun rifle!

[FNGGlock]

My 15-22 has been great, even ran some CCI SV through it and it had no issues. Have had a few stovepipes with a bad batch of golden bullets, but otherwise no issues.
Definitely easy to clean. I don’t take the bolt assembly apart for most cleanings.

So I took it to the range and swapping out the original extractor definitely fixed my problem. Out of around 400 rounds fired, not a single stuck casing or failure to eject.

However, i'm having an issue with the case not even being struck. Very strange. I would eject the round, then I physically inspected it and no mark at all. So it isn't a light strike. I haven't cleaned it yet since my last range trip so I am going to give it a good scrubbing. I have a feeling the firing pin channel might be gummed up.

[ar15barrels]

Mine is brand spanking new so I don't see how cleaning it would fix it.
Literally out of the box.

Most guns are shipped with preservative grease on them to protect them for long term storage.
This grease is not necessarily good as a lubricant for function and should be cleaned off and then the gun should be properly lubricated for function.

This is mentioned in many operation manuals that people rarely read.

This is mentioned in many operation manuals that people rarely read.

I call your attention to page 27 of Smith & Wesson's manual for the M&P 15-22 rimfire rifle:

-Before using your firearm for the first time, it should be cleaned.

-Your firearm was treated at the factory with either a preservative or oil to protect it against corrosion during shipping and storage.

-Preservative and oil should be wiped from the bore, chamber and exposed areas using a clean swab or patch before using the firearm.

So yes, even the manufacturer says to clean the gun of their preservative/oil BEFORE USING the firearm. It's so important, S&W states it not just once, but twice! Apparently, they really don't want you to use that gun before cleaning it first.

But what the hell do they know? All they did was make the gun, right?



Sarcasm aside, there's a few other things to note about the 15-22 according to the manual:

Page 10, Bottom:
The match grade chamber found in the Performance Center M&P 15-22 rifle is designed specifically for semi-autos and is different from a standard chamber in that it will not accommodate the longer case of the CCI Stinger brand ammunition.

Page 13, Bottom:
CAUTION: Never dry-fire the rifle as damage to the firearm could result.

Page 14, Top:
Before using your firearm for the first time, it should be cleaned. See the cleaning section of this manual. (That's three places that state to clean the gun before using!)

Page 16, Bottom:
WARNING: THIS FIREARM MAY DISCHARGE ACCIDENTALLY WHEN A ROUND IS FED INTO THE CHAMBER, IF IT IS DROPPED OR RECEIVES A BLOW TO THE MUZZLE OR FRONT OF THE FIREARM. (THIS CAN OCCUR REGARDLESS OF THE POSITION OF THE HAMMER OR ANY OF THE VARIOUS SAFETY DEVICES.)

Glad to hear the FTEs are resolved. What extractor did you get?

Hmm, no rim strike, wonder if the bolt was fully in battery. Never tested it, but hard to know on blow back systems if it will allow the hammer to drop on out of battery bolts.

The S&W M&P15-22P's are a ton of fun too!! Neat little plinker direct from S&W!!

[deckhandmike]

Man I’ve had a 15/22 for like a decade and only cleaned it maybe three times. It’s so dirty it’s ridiculous and it runs great. About to dust it off and give it a cleaning as my boy is finally old enough to shoot it.

[BigPun762]

Ok so I took it to the range. Still haven't cleaned it lol.

But it's weird, it did a lot better today with around maybe 5-8 of the failure to strikes? I shot close to 400 rounds today.

And it seems to love Federal Automatch though. I ran around 100 rounds of automatch and not a single issue.

Here are some pics of the failure to strike. You can see the striker tries to hit but just leaves a dirty mark.
