my sons 15-22 is on occasion firing 2-3 shot strings on a single pull of the trigger. i know this is not only dangerous but technically a machine gun even if it is a manufacture defect. no modifications to the gun whatsoever and well maintained. however i am not the original owner, and according to s&w website the warranty only applies to original owner. anybody got any ideas or experience the same issue that can lend a hand and tell me what s&w fixed on theirs? thanks to anyone who can help.


UPDATE!!!!

just got off the phone with s&w. they replaced bolt, rails, firing pin, all springs in fcg, all pins. sounds like they replaced all the working parts in the upper and lower receivers. said it will be shipping out monday.

Well, call them and explain the problem with the ownership history. There's a good chance they'll cover it. Failing that, sell it to someone who would love to own it!

Contact S&W and explain in detail what's happening. I'd be willing to bet that you can still get the gun fixed under warranty.

In the mean time, take time to take the Fire Control Group apart. Is there an allen screw underneath the tail of the trigger(towards the butt end of the gun)? If there is, take the pistol grip off, taking care not to lose the little springs and pins held in place by the grip. Remove the allen screw. It is a mod. that if used incorrectly can cause un-wanted and potentially dangerous results.
Does it appear that there has been any mods. to the FCG?

Do you know the previous owner? Did you buy this from an individual or a local gun shop?

Have you cleaned the FCG well?(actually the first thing I should of asked)

Good luck and be safe.

hobie,

no mods to the gun at all i know for a fact. bought the gun from best friend ive known for 10+ years. i have been with him every time he shot it before i bought it. the fcg is cleaned everytime i clean the gun.

Cool.
There's another thread going on right now about the same thing. I'm going back there to read the rest of it.

Be safe!

guess im not the only one this is happening to. i have a brand new fde moe that i took out today too and had no issues from it other than some feeding issues that i believe may be ****** ammo. i usually run federal and i was running winchester today.

called s&w this morning. its going back and they are going to take care of it i presume. ill post updates as i get them.

Brian, I'll say it again, the last thing S&W wants out there is a gun with a major problem and their name on it. From what I've seen on old posts in this forum, they will fix it under warranty for you even though you are not the original owner.

just wondering but is has this only happened when your son has been shooting it or is that not a factor?

How are you cleaning the FCG "every time you clean the gun"?

Some folks think that cleaning requires complete disassembly of all parts. The FCG should not be removed from the lower receiver as part of routine cleaning.

If the FCG has been removed in the past and the hammer/sear surface inadvertently damaged, that could cause the problem indicated.

Also, I agree with HalfSwiss. Unless there is indication of user caused damage, they are obligated to fix the problem. Owners arrested for possessing (and continuing to use) an NFA weapon due to equipment failure is bad press, (Google discussions about "The Accidental Felon").

Sounds to me like sear damage or too little overtravel in the FCG. I know mine worked flawlessly up until I swapped the stock RRA 2-stage for a Geissele Super 3-Gun 2 stage and the Geissele has been a wonderful trigger for speed steel. I have Jard triggers in my Rem 597s do that and only playing with the overtravel adjustment has cured it.

Well stated! Absent some specific problem, there is no need to remove the FCG at all. Simply blowing it out with compressed air is sufficient cleaning under normal circumstances. If one feels compelled to do more, a squirt of GunScrubber followed by the compressed air will leave the FCG spotless. All that's needed for lube is a single drop of oil or CLP where the pins goes through the trigger and hammer.

Many problems can be traced to unnecessary disassembly, over cleaning and over lubrication.

Mine was doubling and S&W installed blue springs it fixed the problem.

my new moe has blue springs in fcg, my sons does not. it happened when i was shotting it too. fcg has never been removed from gun, or tampered with in anyway. i spray it with powder blast and then hit it with compressed air.

im a little pissed with s&w. i just got my label TODAY. to me for the issue thats going on with it and possible legal issues on my end, this should have been a serious priority for them. will keep you guys updated as i know more.

Your firing pin may be gunked up and sticking out, since it is a floating firing pin, when the bolt slams forwards the firing pin, due to forward movement may strike the rim. It should not with enough force to ignite it but it can.. (Same with the full size AR15 5.56/.223), it's called bump fire.

Remove and clean the firing pin and flush out that area, leave dry when re-installing the firing pin. If it continues, STOP and call S&W to get it fixed or find a good gun smith.. Good Luck...

The 15-22 has a firing pin spring that keeps it from floating like the .223. It could have gunk inside it tho as after many rounds of 22 can make it quite cruddy. I've taken mine apart to change out the firing pin spring and found lots of crud there. YMMV

s&w took delivery today.

I had a similar problem with mine. I marked all the springs and sent it to S&W last week. Got it back today and all my springs are the same. They don't even tell you what they did. I will take it to the range this weekend, But it looks like they did nothing......

well thats not cool if they didnt fix it. let me know if your still has the same issue.

Well got it to the range today and was shooting at 50 feet. I had one of the guys on a spotting scope. He was wondering how I was pulling the trigger so fast. Had a few doubles in a row. I guess I will ask s&w to break down for me what they did because I see they did nothing.

I was going to buy an M&P 9C , but if this is how there guns and service works it makes me unsure if that's what I want.......

damn brother. not a good sign i guess. hate they did that, its obviously something in the fcg. will keep you guys updated when i hear something.

Brian, I have a question. Is the double firing happening with the trigger held in the full rear position. Or I was thinking maybe your first fire might happen when you pull the trigger. Then when you release the trigger to reset the hammer the hammer disengages the disconnector but never engages the sear causing the second firing. If you do this quickly it might come out as 2 quick shots.
Or I like Aceman's theory, that is similar to how a full auto uzi operates. Check the firing pin spring.

its not an accidental bumpfire. depress the trigger to the rear and getting 2-3 rnds from that pull. its at s&w now. if its not properly repaired im going to be really mad. this is effectively a machine gun, and this needs to be remedied immediately.

Hopefully S&W takes care of it. It sounds like an issue in the firing pin/bolt (but still could be a disconnector issue). You are correct that it is technically a machine gun and in most states is illegal without licensing.
You would every right to be upset with S&W for sending it back as repaired if it still has the problem. I know I would be. If it gets sent back and returned in non working condition a 2nd time I would then just ask for a complete replacement.
In any case im sure they will take care of it, just the down time can be frustrating. At least you have another to play with

Don't worry. Mine did that same thing and after S&W got ahold of it it came back a million times better then when she left. Before I had an ammo finicky little bugger, but now she eats every kind of ammo out there and I have not had a SINGLE failure of ANY kind since. I can't even count how many rounds I've put through it since the repairs but lets be safe and say it's been a few thousand. Sorry to hear your 15-22 has been acting up, but I promise S&W will have it fixed in no time. Mine was returned in under 2 weeks so your time apart will be short :-)

Since this is effectively an automatic weapon under federal law produced after 1986, fixed that for you.
