What buffer/spring for mid length?

[vossman]

I have an 18inch Daniel Defense mid length barrel I am gonna put on the DD Armory upper once it's ready. My lower has a standard carbine buffer and spring but i am not sure it will work with the longer gas system. Am I gonna break something if I try to run it with the carbine parts?

I run all mine 16"ers with H buffers. No problems at all. Very soft shooting as well

sure you can run the standard carbine tube,spring,buffer with any barrel length including a 18" middy. You can play with the different springs (like x-power wolff) and/or buffers H,H2,H3 etc.

So is the buffer I have an H buffer? Sorry for the dumb question.

You can run it with the stock parts. I doubt it would be any more overgassed that a 16" barrel with a carbine length gas port.

Does it have an "H" on the face of it?

I run a Carbine buffer and spring with 18" rifle length systems. Runs like a champ. The longer the gas system, the less the gas pressure and depending on some other factors, volume. So you would not risk damage and actuall y you end up with a rifle that is not so harshly over-gassed so increases longevity.

My buffer has no markings on it so...... I am just gonna press on and shoot it then. Thanks all for the help.

As long the gun throws brass 3 to 4 o'clock of the gun, it's all good.
