S&W MP15-22

[stormvet]

Automatch is probably my favorite cheap bulk box 22, I?ve shot a lot of it. The only time my 15/22 has failed to fire was ammo related, very strong hammer strikes. Firing pin gummed up or weak hammer spring maybe, I?d check them. Those rounds you posted were barely touched by the firing pin.

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.

My experience with Automatch is the exact opposite. my 15-22 seems to hate Automatch. I get a FTE or FTF every magazine.

My rifle seems to have issues with any ammo that is just plain lead. Any plated bullet runs just fine.

I run generic Federal or Winchester bulk. I about one or two FTE or FTF in every brick.

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

I bought my granddaughter a 15-22p. She loves it. I liked it so much I bought one for myself and put a franklin armory binary trigger in it. It is a blast to shoot. We've had no issues with either of them.

I took some footage. I captured two failure to strikes at 1:43 and 2:25.

Looks like the bolt isn't going into full battery when it happens.

I was gonna get one but took an old upper flipped the gas port and put in my cmmg 22lr conversion bcg. Put it on my lower with pic rail adapter on it.

He switched to CCI in the beginning and it was still giving him issues. But he posted a video of what he did to the rifle and all he did was replace the extractor.

Mine is brand spanking new so I don't see how cleaning it would fix it. Literally out of the box. My HK416-22 did not jam once straight out of the box.

I recently got a Baikal MP161k.



It's a blowback detatchable magazine fed semi-auto just like an M&P15-22 or 10-22.
It is completely missing the extractor and detent and spring.
I ran half a dozen full mags through it with absolutely no malfunctions today.

I was worried that I might have a misfire and the cartridge would be stuck in the chamber because I don't have an extractor but my worries were unfounded.
The gun ran flawlessly.
I still want to put an extractor in it though in case I ever do get a misfire.

I have a 1st Gen m&p 15-22. Like when they literally first started selling them. I haven't used it in quite some time, but I think last time I took it out, it was double firing. Something about the bolt not closing?

According to published specs, that Baikal .22 weighs 10 pounds!!! Is that accurate?

no, the bolt face was not cut deep enough.

Maybe that weight includes a wood crate?

My rifle without any accessories other than an empty magazine locked into the action weighs 6lb 1.6oz
My rifle is missing the extractor and spring though so a complete one might run closer to 6lb 2oz.

Well 7 months later, I finally got the thing running good now. I have shot probably over 1000 rounds since I changed some of the parts and haven't had any issues so far. I only shot 40 rounds in this video but nevertheless, the S&WMP15-22 is now one of my favorite 22s I own. I was shooting some Aguila 40gr rounds in this video:

What parts did you change?

Since the start of this thread I took out my MP15-22 a few times and sometimes would have 1-2 stovepipes a session shooting probably 200-300 rounds. On the last one I was using up some old Aguila SV 40 gr ammo that is a bit weaker and had probably 5 or so ejection issues. With Mini Mags I rarely had any issues. I saw a few Youtube videos on checking ejector alignment and found mine was bend a little down, I bend it back to align better with the bolt and figured I may as well throw in the Volquartsen extractor. Took it out and it was running flawless with various ammo including SV CCI/Aguila, Golden Bullets, Minimags, etc. shooting a ton of rounds fast, slow, etc.

It is well worth looking at the ejector alignment and swapping the extractor if you have any issues. Mine has been pretty solid, but not 100% with some of the weaker/inconsistent ammo. The changes seems to have remedied it, even before that I liked it. 22 semi autos can be finicky and each one may have a trick or 2 to improve them if you have issues.

For reference it would be good for the OP to post what was done to his to fix it.

I swapped out the extractor for a Volquartsen as well.
