OK, now I get your handle, but that's only five...

Not just 5, multiples of each, except the extractor pin.

It's what happens when you use them a lot and don't baby them.

Strange to see ArmaLite mentioned here so much. Mine is the M15 A4 "special purpose". That's just what they call a heavy barreled flat top. I haven't broken anything on it, with about 2k hand loads fired.
A lot of reading indicated that the things that are likely to break are gas rings and bolt parts. Not just with the ArmaLite, but with AR's in general. With that in mind, I keep a spare bolt, firing pin and cam pin in the butt. With mine, I switched to the ArmaLite free float tube. I couldn't keep the retaining nut tight, so I put a short piece of bicycle inner tube over it. I keep extra pieces of that in the pistol grip.
Other changes are a Giessele trigger and a Magpul trigger guard. Ya just gotta' be careful when you're working on things, and they keep on working right!

That's pretty consistent with what I've seen from hard use of Colt M4 and M16 series carbines and rifles. It should be noted that I'm only listing my personal breakage.. I have "seen" a lot of Colts and FN's broken, some to the point of being turned in as unserviceable, I'm working to leave the ones that I didn't break out of the picture.. If I wanted to know what breaks all the time on Colt's I could just send a FB message to my old Armorer LOL!

Interesting and scary to me; besides field stripping I've never messed with my bolt or any piece of it. I've beaten the holy hell out of my Colt and it hasn't failed yet... Beaten to the point where I think my front sight is tweaked. She still runs like silk and reports with a boom when I pull the trigger.

I have noticed my accuracy seem to get more erratic, though I'm thinking that is a sign my barrel is going mostly.

I have built a bunch of AR rifles and put tons of ammo down range and never had any parts breakage.
The last one I just finished and I am trying a BCG sold by AIM that is a investment casting type part.
For the price and knowing AIMS reputation I figured it was worth trying.

Nice! I love a good flogging to see if a part breaks Report back in if it fails.
