Thanks. That’s a good chart. But it confirms. There is little to no to negative advantage to a 16” barrel over a 12” barrel.
If I build a 10mm PCC it should be an AR pistol not a carbine.
Now, if the alphabet agencies would just decide what they’re doing about barrels, braces, and suppressors I could get on with planning a build.
