This is my second build. The first was a basic carbine, so it was pretty well straight forward. On this one,,, I need some help.

I'll be using a 18" intermediate length gas system barrel. NOT MID LENGTH! I have a ST M16 NiB coated bolt. I have the UBR stock. I'm pretty sure I need a carbine length spring,,,correct?  But I'm clueless as to what buffer to use. What do you guy's suggest. I think I gave all the critical info needed. If not, please let me know. Thanks.

Carbine length spring, I would run an H2 or H3

I prefer the H2.

I'm just curious where intermediate length gas system lands within the carbine, mid-length, and rifle length gas system?

It's in between the mid length and rifle. It's 1.5" shorter than the rifle. It's supposed to make for a great shooter with a 18" barrel.

If you plan the gas port sizing correctly you can use a light carbine buffer with the added benefit of reduced recoil.

youre saying that a car buffer will result in less recoil than an h2 or h3?

Wasn't there a discussion about this recently. Something about calling Noveske and asking them what size theirs was. I looked, but can't find it.

A heavy buffer is more weight flying backwards then forward.



ETA To try and describe how it feels, a carbine buffer is quick in how it feels. An H2 kind of dulls it, an H3 you can actually notice the extra movement when it goes forward. Or atleast my mind has me convinced you can feel it. And I cant really tell much difference between a midlength and a carbine gas system other than the carbine sorta feels like it recoils faster.
