AR 15 buffer noise

[kc30121]

There are two things that make noise. One of the first thing I resolved with my first AR. The buffer ( the piece that sets inside the front of the spring ) has weighted balls And the spring. To get rid of that horrid sproing noise take the buffer spring complete out and coat the spring with bearing grease. If you want to get technical Mobil28 is mil-spec grease. Do not get to liberal with the grease or your gun won't cycle when it real good out. That also lubricates the inside. Option two is to buy a spikes buffer. They use tungsten dust to dampen the chatter of the weighted balls. They are just big bearings and can make s hell of a rack with cheap buffers. I usually opt for the Spikes adj. stock kit. One it has the nice quiet buffer and two the buffer tube is coated with dry film. It cut down on wear and makes for a real quiet and smooth action when charging the weapon. A lot of kits have sprirl groves from machining inside the buffer tube and that makes a different racket itself. Go to a gun shop that has Spikes buffers. Shake it back and forth and it's virtually silent. Do those two things and it will quite your gun down emmensely. If you want to invest in the Spikes kit it will sound like a completely different unit. The buffer alone in is 24 to 29 dollars. The complete kit cost around 79 dollars. Follow these procedures and you will illiminate the pesky racket.

I ordered a new spikes t2 buffer but I would never ever put grease in a area on my firearm that’s designed to run dry. Putting grease in the buffer tube will only cause problems down the road. It maybe a quick fix but grease isn’t suppose to be in there.

I've had a light coating of grease on my buffer spring for 10+ years... How much further down the road until I have problems?

Really not sure. I’ve never done it and have a really good friend that gun smith for a high end gun manufacturer around here(head down firearms) and he has always said never put grease or lube where it’s not designed to be on a gun. I called him after I started this post and he also suggested that’s spikes t2 buffer. I just texted him again and asked if I should lube that spring and his response was “hell no”. I can only go by what he says as I don’t have the experience obviously has building guns. Wasn’t trying to be rude just going off what I’ve been told about this subject.

You can talk to 10 different builders and get two different answers. A light coat of and mean a light coat is going to hurt anything. The fact you have had it on there for 10 years speaks for itself. I have one that's had grease on the spring for 14 years. Still runs like a champ and if I take it down and inspect it, it still looks brand new. Hasn't bothered my gun so I will do it my way and let those who don't do it there way. We could argue the point for fourteen more years and my gun will still be running. Might need a new barrel before then but I would be willing to bet if the spring still holds it pressure it will still look new. I treat my guns like I treat every machine I own. It there is two metal parts that continuously present friction it gets lube.

The Geissele spring is quiet.

I meant 10 different answeres. That why some old guns feel sloppy and shot to hell.

Curious what you coat the spring with? It was the weights in the buffer that was making the noise not the spring

Get an armaspec captured buffer system. Jp than JP and you lose the “twang” of a standard buffer tube system. Only about$80.

Vseven makes teflon coated springs, tubes and buffers.

The weights made the noise for the OP, but the first time I shot an AR and heard the "twaaang!" I said "No way."

I did some research, and found that you can lightly coat the buffer spring with grease to kill the twang. I gave it a light coating of synthetic moly wheel bearing grease, and it worked (and works) great. Less noise, smoother action.

Recommended it to a friend; she packed her receiver extension tube with grease. That didn't work so well.

Her rifle worked fine again after we dug out all the extra grease.
