I ordered a non name brand H2 buffer.  The first thing I noticed when I took it out of the package was there was no movement inside the buffer.  My other standard and H buffers have "balls" that roll back and forth when shook.  Is this H2 buffer broke? Or solid maybe?  
Should I use a solid H2 buffer?  It sure seems to slam the bolt home hard.....
Thanks for the help guys!

Not normal, disassemble it and see what's up.  Maybe one of the rubber pads was cut large or something and is hanging up.

ETA:  It's not a critical issue either.  I think the buffer's deadblow effect is to help with bolt bounce.  As long as the rifle functions correctly, it won't hurt anything.

Here is what you are looking for in your buffer. In it's common form Tungsten is not magnetic, so you can use a magnet to determine which of your weights are steel and which are not.

I've seen other buffers with no obvious movement till going through a shooting session.

Besides, the poster above me is correct in the weights doing a dead blow thing for bolt bounce. Bolt bounce is only an issue with full autos.

Well, I believe my 40$ H2 buffer is a POS.  I took the buffer apart, and it's solid!  Not hollow with tungsten weights as advertised.

Where did it come from? Tell us so someone else doesn't get taken also!

I say run it and see if it functions. I wouldn't worry about it if it works.

If dead blow doesn't matter for semi-auto and it weights correctly, why is it a POS again? People actually pay extra for silent buffers (Spikes ST-T2, PWS).

What does it weigh? What was inside? Is it possible that a company sent a 9mm buffer out the door instead of an H2 by mistake?

Because if a manufacturer advertised it as being an "H2" buffer while taking a shortcut like this, that's chickenshit.

Now if they said "H2 weight buffer" or something else that indicated that it wasn't a genuine article, that'd be something else.

The buffer weighs 5oz.  It appears to be solid cast with enough drilled out to install and pin the rubber bumper.  What concerns me is there is no back and forth action inside the buffer.  It's solid. Is that a problem? I've never seen one that didn't have weights that slid back and forth inside.  Is that going to be harder on the action?  Harder recoil?
I'm going to call the company and talk to them before I post the up here and talk to them.

Not saying you are wrong at all. Sounds like a marketing spin and they could actually kick the price up a little seeing how now it is in the 5oz zone. That said, I would send it back.

I don't have a 9mm buffer to take apart, but that sounds like one to me. Someome with more knowledge will be able to confirm/deny that.

I would use the right buffer for the job.

Yeah, it's definitely not going in a 9mm build.  The buffer was bought for a suppressed 10.5" 5.56.

If it's for a suppressed rifle, why not get an adjustable gas block and not mess with the buffer?

No name buffers are no bueno. The bumper I s alot of the time cheap plastic on the shitty ebay no name buffers. Ive seen the bumper break apart in person. Decent/good bumpers are much sronger/better made

All of my guns have UTG or Sportsmans guide $25 M4 stocks. I have not had a problem yet.

Because it won't remain adjustable for very long.

Reciprocating mass also comes into play at the rear of the rifle's cycle.  The weights allow for a momentary pause that allows more time for rounds to feed to the top of the magazine.



Bolt bounce is rarely an issue with semi auto firearms, but if you want to run a bump stock or shoulder bump then you it can become a problem.



This isn't full auto:
