A question and an issue for you AR15 knowledgeable guys

[JEVapa]

It is a normal 10" free float handguard. I am familiar with hearing the spring in the buffer tube. This is way above just noise. It is a very noticeable wobble in the entire rifle probably causing the spring to bang against the sides of the tube. It continues for around a half second before settling down.

Take a video and send to me. The barrel shouldn't wobble. At all. It will vibrate but not wobble. If it's wobbling, then the barrel nut is loose.

Maybe it's going too fast and you're getting bolt bounce and you just think it's wobbling.
What kind of buffer is in it?

It's a standard A2 fixed stock rifle buffer and tube just like on the original M16s. That is why I was asking if anyone has ever seen a heavier buffer for that style. I can't find one.

They don't make them. They're already 5 oz which is an H3 weight.

I believe slash makes them, but you'd be better off switching out springs first in my opinion. My first thought would be bolt bounce.

I like slash's buffers. Heavy Buffers | Products | AR15 Rifle

Can you verify you have a Rifle buffer spring and not a carbine spring in the rifle tube. Sounds like maybe you have a short spring in a rifle tube.

I got 2 different thoughts. One not enough pressure pushing it back. And the other is too much gas and over running the system.

That is if everything it put together properly.

This. Im willing to bet absolutely its bolt bounce.

Let us know what you figure out!

Everything on the lower nice and tight? I like to use Tubbs springs but I do not know if that is an option for you.

What about the upper/lower fit? Any play? Takedown pins being weird at all?

I'll add that 7.62x39 ARs are inherently prone to malfunction. Mostly a gas/dwell time issue and sh*tty mags. Use only Duramags to eliminate the mag problem.

mine has not failed yet do have duramags fingers crossed

O heck fill the stock with JELLO that will settle it down.!!
