I've searched back 3 months and into the archives and found lots of interesting info.
From what I have seen, the 5.6 oz 9mm Buffer (carbine buffer is 2.88 oz - 3 oz) in a carbine will result in less felt recoil and slows down the rate of fire in a full auto carbine.

So other than that, why would someone use one besides for a 9mm conversion? Will it help rifles cycle with lower powered ammo?

The heavier buffer slows down the cycle in ANY rifle. This makes the rifle easier to handle, reduces the "slam-bam-slam" wear caused by carbine-length gas systems, and otherwise improves functioning.

I'm using the standard carbine buffer in my 16" RRA.

To be honest, I didnt notice any change in felt recoil between my 20" w/A1 stock vs. my 16" w/ 6-pos stock. In fact, it almost seems easier to follow through on shots w/ the carbine than my 20". Almost like the recoil is less...or the muzzle jump is less.

It cycles WWB, rem umc, and wolf just fine.

Try the normal carbine buffer first.

In that case I'll keep the stock buffer.
Thanks!

I have a 9mm buffer in my carbine - shoots fantastic and I notice a distinct difference in felt recoil. YMMV. I like it.

My other two AR's have stock buffers.... I may try a 9mm in my 16" middy and see how that fares.

i run the mgi rrb in all of my rifles and it was a very noticeable change

I don't mind the recoil from .223, it's very weak and I can handle it all day long without any problems. After 500rd or so of 7.62x39, my neck gets sore and I have a headache. If I had to complain about .223, it's that I never have enough ammo at the range. I burn through .223 like gasoline through my Ford V8.

My carbine was ejecting quite a ways forward with the standard crbine buffer so for shits and giggles, I decided to buy a RRA 9mm buffer to see how it worked. It has slowed the cycling down enough so that it ejects at about 3 o'clock.

It is basically counteracting the higher gas pressure that is in the carbine gas system by forcing it to move more wieght when unlocking the bolt.

I like it. Hell, I even put one in my mid-length, although it wasn't as needed there as it was in the carbine.

I figure if I shoot Wolf, it's going to even out in terms of recoil w/ the stock buffer.

I know I should try it, but would Wolf cycle with the 9mm buffer? I used a Wolff XP action spring on my AR rifle and Wolf would not cycle. When I used the stock spring and stock rifle buffer, M855 would eject cases at the 12/1 o clock position. Wolf was ejecting at 4-5 o clock.

i have had zero problems with any ammo using the mgi buffer

I have the RRA 9mm buffer in my carbine and my father has the standard buffer in his carbine. You can tell the difference with both recoil and muzzle rise. They are both less. As always, YMMV

+1 with Enidine and 9mm buffer... even Wolf.

So the probability of the 9mm 5.6 oz buffer working with Wolf ammo in a 16" carbine is 100% assuming everything else is working?

Should be...

Once again

Buffer weights control the functioning of the firearm (keeping the firearm from shooting itself apart, etc)

Cyclic rate is a secondary function.
