I just got a new (to me) AR15 lower, and I'm noticing that after every round is cycled the spring in the stock rattles away really noisily. Should I swap it out for a new one, ignore it, or do something else all together? I've never noticed this in any of the other AR15s I've shot.

My AR15 technical knowledge is a bit limited, so any help would be appreciated. :)
 
Frist by your post it seems you are new to the AR world.
- if I am wrong please foget this part
- if i am right then :welcome: to AR's

Second
- Mine did the same thing, its normal. After a few hundred rounds you will forget it ever did that :D

Have fun

HINT: Your only choice to fix this problem is get yourself a 10 round mag (LAR of course) and empty it as fast as possible, this fixes a lot of spring issues :ar15:
 
The sprong is normal on carbines. A light "sprinkle" of lube on the buffer/spring will help some, get a heavier buffer or get a middy or rifle length gas system which does not sprong nearly as much.

True enough, but lubing the recoil/buffer spring isn't necessary, it accomplishes nothing other than to collect crap when firing.

The spring/buffer and spring/tube are contact points. Heavy lube on the spring removes the noise in my experience and from all the AR manuals I have. (Although I agree it isn't a neccessity) What crap are you getting all the way in there to worry about?

I agree... even with thousands of rounds worth of fouling, the worse that will happen is that it just gets squeaky again. It's not like the buffer spring is of tight tolerances in order for the firearm to operate well... as long as it shoots back and then springs back forward, you will have a working firearm.
 
You can lightly grease it - if the npise really bugs you. The grease will work as a better dampner than a light lube -- but remember not too much.

If its a duty gun - lubing it would be a bad idea - but its a civilian gun and it it enhances your enjoyment - then do it...
 
The contact between spring and buffer tube is minimal and not a load bearing surface. The manuals you mention probably list a 25-300 zero which is also a useless piece of trivia. The tube and spring are generally the cleanest areas of the rifle after firing but carbon and foreign debris(grass, sand etc) does work it its way into the tube. If you use oil it all ends up inside your lower receiver or being blown out of the rifle altogether, so how effective was it? I do clean then wipe my spring with an oily patch or a tough cloth to apply a thin protective coat. The tube gets wiped clean.

But Kevin, everything I lube enhances my enjoyment! ;)

That's why I use grease. How can one complain about a greasy tube? ;)

Ha two comments one stone!

P.S. The manual(s) only indicate use of grease on the spring if the sproingy noise bugs ya. (Which it seems to bug our boy cancer, and did me because it was remarkably loud on at least one of mine. My Panther you don't hear it at all... of course it is a much louder rifle in .308)
