Eliminating Buffer Weight Slide

[scoobydo]

Would opening up the buffer and adding spacers to the tungsten weights affect performance?
I know the thing is supposed to make a spoing noise, but it is the buffer weight-shift I am talking about.
I heard some people eliminate it by adding spacers and making it solid-feeling and others who say the weight-shift is needed to eliminate felt recoil.
Is there any definitive info on the subject?
If it is all the same, I would rather space it to eliminate the shifting "thwap" noise.

What's the problem are you trying to reduce the reciprocating weight or eliminate the sound?

If you want to reduce the reciprocating weight you could go down to a lower weight buffer and add a LMT enhanced carrier or buy a red springco spring.

If you wanted to eliminate the sound you could lubricate your buffer spring and add a loud brake or buy something JPE makes.

Am I interpreting this correctly by saying that you want to keep the buffer from sliding at all?

No, nothing to do with the spring or carrier.
I have an lmt basic waffle kit that comes with a heavy buffer.
If you hold the buffer weight in your hand and teeter it back and forth you can feel the weights inside shift/slide back and forth.
If I take the roll pin out (to access the weights and spacers) and add more spacers to eliminate the empty space, will thus affect performance?

No, this only pertains to the weights and spacers inside the buffer.

Use a scale, remove weight, add lighter weight spacers to take up more room.

Op, you using 22lr in that ar?

I dont think he wants to remove any weights, if i am reading his post correctly, he just wants to make his buffer more "solid" so when you shake it it doesnt sound like s spray paint can.
I cant think of how it would hurt. But I dont claim to know much either.

Yes, but if you just add spacers without removing weight, you increase the weight of the buffer. If you want the buffer to remain the same, you'll need spacers that weigh less than the material you're removing(so they take up more space) and keep the total weight the same.

Although considering the various sproings, clicks, and bangs that happen when using an AR-15, I think complaining about the weight in the buffer moving is silly.

Correct.
Its hard to explain without somebody thinking I am talking about the spring or the noise it makes.
My thinking was that it could not hurt.
However, I am not as informed yet.

You could try out a 9mm buffer. I have a 9mm buffer from (I think...) Rock River Arms, and it's pretty solid. There is no discernable shifting of weights within the buffer, although it is heavier than a standard 5.56 buffer.

Spikes Tactical buffer is another option. It uses powdered tungsten rather than solid weights. The shifting of weight is still there, but without the clacking sound.

You must have visited the Spikes tactical site and read up on their high speed low drag tactical buffer that doesn't have any moving weights.

I don't think I have ever even noticed this. Like was posted above, with all the other noises and vibrations in the AR platform, what is one more slight wobble? It doesn't effect accuracy, it doesn't effect weight, and it might effect how your rifle eats certain rounds unless you get the buffer weight exactly what it was before. Why fuss with something so minor?
Sorry, OP. I'm not trying to sound like a jerk here, just pointing out that spending time and effort fixing this is like worrying about scratching up the lower on a working rifle. Who cares about it as long as it works right. Now if this is a Safe-queen/range toy shot from bean bags only type gun and it bothers you that much, by all means fix it.

[scoobydo]

I have been informed that the shifting is there to eliminate bolt bounce which could cause a failure to feed.
Thanks all for your help.

Just buy a Spikes Tactical buffer. They make them in different weights and they are filled with tungsten powder and don't make noise or move.
