I'm considering a 13.7" Ballistics Advantage barrel in 5.56 (carbine gas system) in a pistol build.  I've read all kinds of stuff about carbines or middys having issues with pistol tubes/buffers.  

What would be a good buffer in my build?

Dependent upon the ammo you chose to use, but for quality ammo, you should be fine with an H or H2

thanks.  I'm thinking I'll stick to 75gr GDHPs since I've been sitting on about 5k of them for years after PSA had a sale.  I only see them discount the 64gr GDHPs these days

Im not sure how much, if any spare parts you have on hand. I have accumulated a few bits over the years.
If you have to buy one, I would start with an H2 for that ammo and barrel.

Or just build your own with KAK  configurable buffer kit and make any weight you want and then some.

I have a 10.5" pistol with the carbine gas system, 5.56mm.  I use an H2 and it has worked great so far, only have put 70 rounds through it but no hiccups.  I also have a 7.5" with the pistol gas system and use an H, also with no hiccups, but about 500 rounds so far.
