What buffer weight and spring for a 10.3-11.5 barrel with a carbine gas system. I know that it is dependent on the individual rifle but what is a good starting point?



If you start with an H2 or H3 you can always take a weight out and add a spacer if you need to go lighter.

If you need to go heavier, the damn tungsten weights cost almost as much as just buying a different buffer.

My 11.5 with a suppressor needed an H3. Suppressors add a lot of gas back tot he system so without it and H or H2 would probably be fine.

In your shoes I would probably start with an H2. H3 would be extra safe as you can easily lighten it yourself.
