The 11/111 Hunter XP (NOT the Trophy Hunter XP) package guns come with the round receiver/non-Accutrigger configuration. You might want to go ahead and pick up a Rifle Basix or SSS trigger to replace the one it came with, especially since it seems like you're going all out. If you can't return the Warne base there's a fair chance you'll be able to trade someone for the correct base in the classifieds. You got one hell of a deal, congrats!
