Hello. Went with the  556/223,10.5" bbl build, what's ideal buffer weight for this length bbl?  Carbine length gas/non supressed. Thanks for any help.

I have H3 buffers in both of my 11.5" rifles and they run fine suppressed or not. If you aren't using a suppressor, H would be just fine.

Edit: maybe I'm dyslexic, but I could have sworn the original title was asking about 11.5", lol.

Depends on your gas port and which length gas system, but I'd just throw an H2 in it and see how it goes. Odds are it'll be fine.

Mine has a standard carbine buffer, runs fine.  It would probably run fine with an H3 as well, haven't tried.  All buffer weight is likely to change is the ejection pattern.  Make it reliable, FIRST, then you can play with it
