It is obviously designed for classes that don't care about weight. If it gives better AP and you don't care about weight why wouldn't you use it?
Because if you already have the base AP mod, the increase in penetration isn't really all that great. It's not going to fire through WALLS, right? Only light cover/enemies. If you've already got a maxed AP mod then that's about all you'll ever need in most situations, unless you have like 4 guys perfectly aligned behind a railing...which isn't going to happen often.
As for the increase armor reduction, this is also rather minor. Sure, you'll get a few extra points out of every shot, but the extended barrel will increase your
base damage by 25%. In all but the lighest of weapons, this wil lead to higher damage number than the armor reduction will.
Sure, you could take another mod besides the Extended barrel, such as the new scope or an omni blade, but you could do that with just the regular AP mod as well. So really, about the
only people that will really benefit from it are Destoyers or Demolishers that don't care about cooldown, and want max armor penetration and a scope...everyone else will probably just stick with the AP mod.
