Yes it is. It is also not germane to his question.

True, but I like to spread the message of the Medicine Stick as far as I can.
On Topic: I never used the Trail Carbine much(even with the scope) and I always hand my Brush Gun off to Cass as soon as I get one. Though from what little experience I have had with these two weapons I personally like the Brush Gun more. I've never felt the need to use it in VATS and haven't had any problems with it. The Trail Carbine can fire two extra shots, has a little over triple the HP, has lower requirements and its ammo isn't quite as rare. The Trail Carbine is more useful in earlier stages, though it'll probably be quickly replaced by the Hunting Rifle. The Brush Gun which is more powerful, has a higher DPS, weighs less and has a higher crit damage will be more useful later on when you start facing Deathclaws and either Legion veterans or Ranger veterans...or both.
I'd say ignore the Trail Carbine, give the Brush Gun to Cass and use a fully modded Hunting Rifle instead.
