Or will a carbine length receiver extension and 3oz weight work ok?
Thos is for a 20” barrel that uses rifle length gas tube.
Hope this basic question is ok in this forum.
Thanks

yes.
Eta: Hope I didnt cause confusion. I meant yes it will work with carbine RE/buffer, not yes it needs a rifle RE. Oops.

Carbine tube, buffer, and spring.
Not sure what weight buffer to use.
The Canadians use such a configuration as their C7A2 service rifle. IIRC it uses an H3 buffer or equivalent.
Someone will probably recommend the Vltor A5 kit as well. I can't recommend it from any first-hand experience, but I seem to recall that it was designed with a 20" barreled rifle in mind.
It looks like rifle and carbine buffers have the same length of travel, but the rifle system has a longer buffer in a longer tube and has heavier weight in the buffer. If that’s the case, then it’s pretty simple to find tungsten weights to make a carbine system buffer and tube work with a rifle length gas system on my 20” barrel. Yes, the tungsten weights aren’t cheap, but it would add flexibility designing a system.
If they’re not using tungsten, but the actual buffers are the same size (C = H1 = H2 = H3 (size)), then do heavier buffers use lead for weights instead of steel?
The H6 is the official carbine buffer to use with a 20" rifle gas.
My experience is that you can really run any buffer with a 20" rifle.
My 18 inch SPR (rifle length gas) runs fine with standard carbine buffer and spring.
