    It won't make a difference either way.

    We can all benefit from Stick and Grant's knowledge. When they say something, I pay attention. Everything I know about the M16/AR15, I learned from the Military, which wasn't very much. They gave me a comic book and a spray can of WD40.

    Guns are supposed to be lubricated properly; this is how I lubricate my duty gun:

    Inside upper receiver
    Barrel extension
    Oprod
    Piston
    Adjustable gas regulator
    Charging handle
    Ejection port cover spring and pin
    Forward assist (never used, but it's a moving part)
    Trigger springs
    Selector switch and axle
    Mag release
    Bolt catch
    Buffer and spring
    Bolt carrier
    Bolt
    Firing pin and spring
    Cam pin

    The inside of the upper receiver and the bcg gets the most lube, the other parts get a "light" coating; enough so I can see the lube on there. Never had an issue.

    As for the statement about getting dirt and debris accumulated in the receiver extension if you lube the spring, I find it highly unlikely based on my experience. That area does not get very dirty.

    And again, excessive lube is mostly an issue for external parts on the AR, and for crew served weapons, in sandy/dusty environments.

    I have never had an issue with weapons that are properly lubed. I have had and seen issues with dry guns, both crew served and AR's, in most environments, including in the middle of firefights (not my rifle, but weapons in my team).

    The devil is in the details, and my advice is to be meticulous in your approach, to ensure proper function when you need your weapon the most.
    It's not about surviving, it's about winning!

    When I install the buffer I hose the spring down with Breakfree CLP spray and then roll it on a dry shop rag to get the excess off and then install. Every few years pull everything clean buffer, spring and tube with Gunscrubber, braklleen, slip 725, etc. and then relube spring and install.

    Look, there are so many thoughts and OPINIONS on how to clean and lube (what portion of) the platform. Bottom line is if you are counting on it for defense of yourself AND OTHERS, you need to be responsible and insure you have it in the proper state of cleanliness and lubrication.

    Also, if you haven't noticed or caught the name, Arctic1 and Norway means it's cold and apparantly his gun isn't freezing. And yes, blah blah, he has a piston--which still has springs in it.

I don't see how reducing the friction between the tube and the spring can be bad. Feel free to run yours dry though if that's your prerogative.
    Most of the quality RE's on the market have a dry film lube on the inside of them.

    The spring (with rolled edges) does zero damage to the inside of the RE.

    In regards to the spring, this is a wear item (3,000rds) so the odds of it rusting before needing changed out is close to zero in my experience.

    Unfortunately, I have logged more training ours in pouring rain than I can count. It is so bad that many of my friends assume that once I step foot on the range it will rain.

    Point to the above is never once have I had a buffer spring rust.

    The FCG does benefit from oil. Look at geissle triggers for example, the manual says to grease the engagement surfaces and keep the pins oiled.

    Definitely helps, but not essential. I oil the FCG once in awhile and grease the sear surfaces.

    Tried lubing the spring/tube, but found it just got dirty. Wiped it all off and have never done it again.

    It's self lubricating. Whenever I decide to clean, it's covered in dirty oil and carbon from the BCG...
