What are these parts? Did they come from my rifle?

[braveally]

I saw this on my shooting area today and just want to make sure these didn't fall of my rifle or something. I'm new to the platform and just took my new M&P out for the first time. I had no problems with the rifle though. So can someone identify these parts and how i can verify the are not mine?

When did you find them, at the range shooting or at home cleaning?? Looks like it might be the spring and detent pin that holds the buffer and spring in the buttstock. More info would be helpful.

looks like the bolt catch spring & detent but don't know how those could fall out. did you clean it first? perhaps somehow there were extras in the box

I found then on the bench i was using at the range. I have not made any adjustments to the bolt catch and didnt open the action at at all while at the range. Im hoping i just happen to cone across these parts and nothing unexpected happened.

Not unless S&W uses a plastic plug...and spring looks short.

Really no scale or perspective of size but my only guess would be a non-milspec extractor spring and insert.

These parts came from something else. There are not AR-15 parts. They came from someone else's gun/gear.

When I find spare parts, I put them aside, if they came from my gun, sooner or later I would be the first to know.....

The best time to discover parts from your firearm are after you completely disassemble it, clean it, put it back together, and discover one, two or three thingies laying on your bench.

There are lots of great videos on youtube on assembling the Ar family. It is a very simple rifle

I had no idea that you would get that bench after that guy with the Taurus product.

I am the REJECT man for the range (Range Elected Judge in charge of Ejecting Cool Things).

I finally had to kick him out after numerous stovepipes, failures to fire, double taps, and all this even after I loaned him my ball point pen to fix his Taurus. Ballpoint pens, especially those made in China, are known to be excellent original spare parts for Taurus.

He never did give me back my spring and push button.....looks like you own em now.

Yep, I agree.

 

[arnoob]

Erm, nope. It doesn't look like the buffer retainer or spring, at all. Don't look like standard AR parts to me

 

[Kadonny]

Yeah, not anything I've seen in a milspec rifle. I've built quite a few so I sort of remember what all the springs and detents look like....and none look like those in that picture.

 

[cyphertext]

It almost looks like some type of swivel stud... can't tell if there is a hole in it or not...

 

[braveally]

In either case, my rifle seems to be functioning correctly. Very likely that it was left over from someone before me. I've put them in a small ziplock and stored them in my safe for keeping. Thanks for the help everyone. Because I'm new and have a habit of breaking stuff, I get worried when stuff like this happens.

Looks like an AR front sight post spring and plunger, but can't tell what size it is. I actually found something similar at an indoor range I was at.

The front sight post detent is cylindrical with a small...protrusion,
on top. It's metal and lot longer than it is wide, and spring runs up inside it.
