It does the job just fine - Luth-AR Double Tungsten H2-Buffer

This buffer is... okay. It's exactly what it says it is: an H2 buffer. I noticed a slight difference in recoil impulse—it’s a little smoother and a tad softer shooting than a standard carbine buffer. It cycles reliably and does what an H2 buffer is supposed to do.

There's really not much else to say about it. It's a weighted piece of metal in a tube. It works. The build quality seems solid and it looks well-made. It wasn't the cheapest option, but it also wasn't the most expensive.

It's not a flashy part that's going to change your life, but if you need an H2 buffer to tune your gas system or reduce recoil a bit, this one will work just fine. No complaints, no excitement. It’s okay.
