    [SUB][/SUB]I just purchased a lightly used Anderson Manufacturing AM-15. Despite the shortage, I paid a fair price (thanks Northwest Armory). My intention for this is a accurate varmint rifle.

    first question, I can hear the spring when I shoot and I don't like it.
    Is there a product or practice that will quiet the noise of the buffer spring in the tube?

    Second question, there is some wiggle room between the upper and lower when closed. There doesn't seem to be any wear that would cause this and doesn't seem to effect anything. Is this anything that needs fixing? If so, how?

    Thanks in advance

    Don't wear any hearing protection, after awhile you won't notice the spring noise anymore.

    Your always going to hear the spring/buffer "twang" using standard type buffers. If it annoys you that much you could take your chances with a spikes powder buffer ST-1 or ST-2. The wiggle between upper and lower is normal and if under .020 checked with a feeler gauge is within mil-spec. If the wiggle bothers you place a 5/8"od 1/2"id by 1/16" o-ring around the front upper receiver take down post, wiggle gone.

    Brimstone Gunsmithing advertises a Trigger work and Reliability package for $80 : "The 'spoon on a cheese grater' sound of the buffer spring will be gone". I can't comment on the AR work, but Dave does do outstanding work on a 10/22 trigger, so I'd expect the same high quality work on an AR. BrimstoneGunsmithing - AR 15 Trigger/Reliability Package

    That sound is part of the charm. Kind of like a Harley, nothing else sounds like it. Learn to love it.

    Grease the spring. It cuts a bunch of the noise.

    Grease the spring or try a springco buffer spring. Some tubes have a very rough bore and will always make noise. If thats the case you can try polishing the tube or just replacing it.

    Shoot it? then shoot it some more, then some more. Then keep shooting until you're focusing on your target and not the noise :)
