I racked the charging handle, pulled the trigger, heard the firing pin go click, but the rifle doesn't fire.

Its not the ammo (new matchgrade), as it happens each time I place in a new full mag, or pull out a partial mag and then re-rack a round.

Anyone have any idea what I may be doing wrong?

Is the pin hitting the round? Is there an indention on the round?

Is your FP in all the way? ummm, any way you can post some pics?

Also, take your BCG out, and you can push the FP down and see it come out of the bolt. Does it do that?
 
Ok, I did as you asked and the firing pin came out, about (guessing here) maybe 1/32nd of an inch.

No, there were no indentations on the shell after I ejected it and re-racked.

Could it be I'm not racking it violently enough? I'm stumped.

All you need to do is pull the charging handle back all the way and let it go don't ride it.

Have you tried hitting the forward assist to make sure the round is fully seated?

I tend to recommend that people never perform a function with their rifle that centers around the words 'racking it violently'.

Not much need for that. :rolleyes:

Your bolt is not locking up. Can the rifle fire a round if you drop one in the chamber, and close the bolt manually? By this, I mean 2 tries; first by letting the bolt fly home with a round in the chamber. Second by releasing the bolt while holding the charging handle, and letting the bolt come home slowly. Almost certainly, the bolt will not close, and you will need to use the FA to seat the bolt. Push it firmly, but do not do the 'Nam slam' on the FA.
We want to understand if the bolt is not able to rotate in and lock.
If it fires both ways, then we are back to a magazine issue, or something related. If the bolt closes hard and fires, then the rifle is fundamentally okay. Might need tweaking. If the bolt does not close enough to fire in either scenario? Need to look to the bolt interface, and how everything is set up. And, how are we lubed, and where?

A bit of poking and prodding, and this will get figured out.:)
 
Next I go the range in a week or two, I'll try both procedures and get back to you, probably by message.

Lube is milspec.

Also, the M&P seem to be set up very tight, and as such, I think they will need some breaking in; it seems to be a round count of 2-300 when they come in to their own.

Good luck with it!!;) Paul.
 
The new MAGPUL PRS Stock and "Raptor" ambidexterous charging handle I installed, wouldn't have caused my problem, now would it?

Just curious as to the variables I didn't mention in my original posting.

I suggest locking the bolt open, then inserting a loaded magazine, then using the bolt release to load the chamber. Leave the charging handle locked in place. It should fire. I suspect the charging handle may not fit and may slow the BCG down when "racking" to load when the bolt was forward on an empty chamber, therefore causing the bolt not to lock up. My M&P 10 worked from the beginning with no malfunctions and I have only 100 rounds on it. Of course, I still have the stock charging handle in place. My expierence indicates that these guns do not need breaking in. Just leave it stock and feed it quality Made in the USA 308 ammunition. I have Raptors in my M4 carbines and I want one for my M&P 10.
 
Besides the obvious of putting the stock equipment on and verifying function, let's talk about your rifle. Most of my experience has been with M16s while in the military, but the principles should be similar.

How long have you had it?
How many rounds have you fired through it?
When did this issue start?
Is it consistent, or intermittent?
Have you cleaned the bolt carrier completely? Not just wipe it down, or spray it with cleaner. Take it completely apart, and scrub/scrape everything out of it.
Have you cleaned the bcg locking lugs in the upper receiver?
 
Appx 1 month new
350 rd count to date
Immediately
Intermittent
Yes...cleaned it at time of receipt and after returning home from each range visit...and used Milspec Oil for lube.
Yes, cleaned lugs.

I spoke to CS at S&W this morning and they want the rifle returned, so I appreciate everyone's help.

Now its a waiting game.

Will update on what S&W says when they return it (hopefully soon) !

Thanks guys...

Just a word of thought after purchasing a new firearm.
1. Read the manual
2. Clean and lube as recommended.
3. Reread the manual
4. Fire in as received condition to check for problems before swapping parts. Fire the recommended amount of rounds if there is any. Tempting to replace parts but hard to trouble shoot problem if you don't know it is fully functional from the factory.
5. If no problems start your personalization of your firearm. Note if any problems occur then swap parts beck to see where problem is.
6. Did I mention to read the manual.

You probably already know this but reminders help refresh one's memory. If anything to add I'm sure someone will chime in.

just my .02 which I go by and works for me.
 
I would have suggested a very close inspection of the bcg/firing pin assy, looking for odd wear marks and burrs.

Hopefully you get yours back faster from S&W than the last weapon I sent to them for warranty work.

If you have snap caps. Take a piece of paper tape, and put it over the back of the round.

Slide the round into the chamber without a mag, rack the charging handle then fire.

If the pin is hitting the round, it should make an indent in the paper. then youll know that its at least making some forceful contact.

Good way to check without firing a live round.

Also you can take a BIC brand pen *or a pencil with a GOOD eraser and drop it down the barrel after pulling the charging handle. Fire. If the pen doesnt shoot out of the gun. Your not engaging correctly or the FP is not functioning right :-D

*tricks i've learned during gunsmithing without a range* :-D
 
Murphy's Law...

14 days ago my New M&P10 was received by SAW for Repair/Tweeking.

So today August 5th I call 'em to learn the status of my return.

Well...they all went on a company wide vacation shut-down from July 31st through August 11th.

Wish they would have told me that when I spoke to their CS Rep so I could have been the one to make the decision to wait on returning it (and stay armed) or in Sniper's lingo "Send It".

I'm bummed out and I am at the point to where I'd like to sell it back to SAW considering everything I'm reading on this Forum about the 10 being problematic and/or troublesome for a handful of owners.

Ugh...My Frustration lives on.

You sayin' that the M&P 10 is the only firearm you have??:eek:

I am cool with it, but that's a helluva first gun to purchase to protect yourself..........:rolleyes:

Be patient. Once they do their thing with it, and make it work, then you get to play with it, and see if it will digest every type of ammo you feed it.
Personally, my recommendation is that if it comes back better, but is still a bit of a picky eater, then start reading up on the recommended fixes for the rifle we have already suggested.

I hate to tell you this, but the fix for that rifle is often a couple of 3/8 oz. egg weights for fishing, or a couple of steel bearings around 1/4-3/8" diameter. They are rarely really complicated to tune up.
 
after about 150 rounds down range, and switching my lubrication to Moble One Synthetic, mine runs like a sewing machine... and groups are tightening up...I am not getting rid of mine
