I am new to the AR world and have exceed the 5000 round mark earlier this weekend. If this has been asked before, please accept my apologies. I did attempt to search for my answers before posting this set of questions:
How does the wear and tear look on these parts:
It appears pretty typical to me. Don’t see anything that would cause me to think something was wrong.
Is it having issues? Are you new to the AR platform? Just curious.
I apologize for not including the facts that I have zero issues with this weapon (M&P15 MOE OR). I was in a hurry to post the message before I started dinner for my boys.
Push down on the ejector, how much resitance is there?
Your action spring is possibly due to be replaced. Some will wear and last better than others, it’s best to measure it. There is a given range within 10" that can be found by searching the forumMaybe new gas rings. With your bolt installed and cleaned in the carrier and fully extended, does it stay extended under its own weight? This can help check the gas rings Assuming the extractor still has “sharp” edges it should be ok. If you are worried about it you could buy the BCM repair kit and replace the spring. See Igunz reply.
Wear looks normal, above recomendations are just preventative maintenance.

Why would you tell him to replace the action spring and gas rings? The requisite for replacing these items has nothing to do wtih round counts.
You measure the spring and if it falls below acceptable lengths you get a new one.
Gas rings are also tested after being properly cleaned. The method of doing so has been discussed numerous times.
The extractor spring can be tested by pushing down on the spring. If it feels mushy then it should be replaced.
A smart AR person will always keep little items like this handy. 
As far as how the carrier group goes together:
The bolt fits quite snuggly into the carrier and does not move when I stand the CGA on its back end or on the bolt face.
The firing pin shows no wear on the tip, but accumulates a coating of carbon that required the use of a brass pick to remove all of it.
The edges of the gas rings appear to be nice a sharp still (At least looking with a magnifying glass).
The rifle prints 1.5" groups at 100 yards with my 9x scope (With my Aimpoint PRO, the group is due to me ;-).
I use the weapon for my pig collection program and it does quite well with the standard American Eagle 5.56x45 NATO 55 grain loading as well as the American Eagle AE223 55 grain loading.
I tried Black Hills Ammunition (55gr to 77gr), group size really wasn’t different enough to justify the cost difference.
Besides, I have yet to have a pig argue after I place a 55gr FMJ just in front of the ear and behind the eye.
Those were the areas I would look at for preventitive maintenance. Those items can show wear in 5,000 rounds, thanks for mentioning that round count is not the best judge of wear I should have said that first. If everything checks out drive on, but if the OP is worried about it, IMHO these would be the things to check/replace.
OP, with your bolt installed and cleaned in the carrier and fully extended, does it stay extended under its own weight? This can help check the gas rings. What length is your action spring currently?
ETA: Edited my oringinal recomendations as well.
Here’s some pics of my piggie getter.
Edited:
Added a pic of the buffer spring with a measuring tape.
Since size matters, do y’all think it needs to be replaced?
Your spring is still good. 10 1/16" is the minimum.
Thanks for the assists everyone. I normally shoot American Eagle 55 grain FMJ AE223. However, I just found a good deal on the 5.56x45 NATO 55 grain FMJ from Cabela’s and jumped on it for 400 rounds. The NATO stuff is roughly 300fps faster than the 223 stuff. Group size does not change and the POI is close enough out to two hundred yards, the piggies will not care.
Mike, where in Texas are you located?
Near Mansfield, TX, you?
Those parts look great to me.
I have a bought a little more rounds through my BushMaster and it is still going strong with just a little wear on it and from shooting a lot of steel case Wolf ammo .I put a BCM extractor on mine and it is still holding up :neo:
Your carrier rails look better than my unfired “but hand cycled” LMT. :lol:
yeah… to the OP- what kind of oil are you using? it’s working. 
When out hunting (The fields can be quite dusty) I use Mobile 1 Synthetic 5w-20 liberally.
When target shooting, competing in carbine matches (Just started those), or when it is wet outside, I use Mobile 1 Synthetic Bearing Grease.
After shooting, I usually just run a Hoppes Bore Snake through the bore twice, strip the carrier group and clean it as well as wipe out / down the buffer tube and buffer.
When I clean the bore, I use Gunslick’s Foaming Bore Cleaner (I use a pipe cleaner and compressed air to clear the gas tube).
To clean everything else, I use Safari Charlie Gun Lube. This stuff is awesome for cleaning the areas around the gas tube end in the upper as well as the charging handle slot and the bolt and carrier assembly.
I like your lubrication of choice.
I am now worried about the next post :jester:
