Have a question for you seasoned builders.. I'm building my first and have a heavy buffer and going to use a 16" barrel. My question is, should I use a carbine or mid length gas system?  Thanks in advance

Who makes the bbl? Gasport size is important. FWIW, my BCM 16" LW midlength uppers run 100% w/an H2 buffer & Wolf XP spring, even w/PMC Bronze (YMMV).
16" I prefer midlength, 14.5" I prefer carbine.

I haven't purchased a barrel yet. Not sire which manufacturer I'm going with.

For a 16", I'd choose to do mid length gas system. Longer barrel than the carbine, longer gas system than the carbine is probably ideal. (and supposedly is)

Why have you decided on a heavy buffer before deciding on anything else?  I agree that a midlength gas system is a good idea, but with that you won't need anything like a heavy buffer unless the barrel you get has a badly oversized gas port.  In other words, if you get a barrel from a decent source, a standard buffer will be fine.

Rookie sh!t starting with the buffer....in a year or two you'll see..
Take the good advice and read/study more.

Mid-length for me, also I start at H2 with a CS flatwire spring.
So far I have had one weapon where I had to go to a lighter buffer.
Since I already have them it is not like it is a big deal to change buffers or springs.

I used to have the tubb flat wire spring. It's too noisy for my. Went to a SprinCo white, I love it.

Another vote for midlength.  Softer shooting than a carbine, in my opinion.  I prefer a 16 inch barrel because I can mount a bayonet but 14.5 + pinned comp midlengths are the shit as well.

I am pretty new to the AR scene, but I am pleased with my two 16" middies. I also like Black Hole Weaponry barrels.

Yes, Direct Drive it is rookie sh#... I'm learning as I go. Picked up the buffer at a show dirt cheap so its not a big deal if I have to change it out. Thanks everyone for their sugesstions.  It's been fun for me doing this build. And I've learned a lot and still have much to learn.

I'd also say Midlength.

I usually start with a H or H2 buffer and see what it does.  Standard carbine buffers are cheap and everywhere.  

Personally, as far as gas systems go, I like:

Pistol on 7"-9.5"
carbine on 10"-13.7"
Mid length on 14.5"-16"
Rifle on 18"-20"

I have built all of the above and formed my opinion based on the performance.
