AR 15 buffer noise

yessir and from what you're describing it sounds like your buffer is missing some weights and probably why it's shifting back & forth. if your gun runs good w/o the missing weight, just fill it tight w/cotton balls.

Haven’t shot the lower yet. It’s a PSA lower I bought from them new last week.

maybe they used 1 heavy weight that didn't fill up that space instead of 2-3 lighter weights? or someone forgot to "fill it up". weigh them on your kitchen scale & compare.

Should they weight the same?

3 oz is standard BUT people often change the buffer weight to tune their guns.

There is 3-1oz weights in it. These are just a lot more noisy when they slide then my other ones. Guess I will swap it with my other non hunting rifle.

Just ordered the spikes t2 one so hopefully we are good

The Spikes T2 Buffer is a machined billet body filled with crushed tungsten powder. This tungsten powder buffer takes the snap and jerk out of the average carbine AR system and replaces it with a Cadillac smooth, easy to control action that's quiet too.

Ok I know I’m probably splitting hairs but you can hear the weights/buffers in my buffer when you tilt the gun back and forth. This isn’t a big deal but I’m setting this gun up with a 350 legend as a hunting gun and don’t want the extra sound.
Any advice on how to get rid of the noise? Should I get a different buffer? If so what kind? I have other AR’s that don’t make noise so I guess I could just swap the buffer from one of them. Lol

They have specialized buffers that are "silenced" buffers.

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 cold 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. No matter which way you go still put a light film grease on the spring. It prevents wear and quiets the spring a lot.
