I picked up this Grade VI Citori Trap back in the 90's when I had my FFL for just $1,500.00 new in the box. A distributor, (I believe it was Green Supply), had a closeout on them at the time. The only difference is it's got pre Invector Plus Choke tubes. It takes the regular Invector models that are a bit shorter and are not interchangeable with Invector Plus chokes. I have a full set of tubes for it, so it really doesn't matter that they don't interchange with my other Citori Trap Grade I, or my BT-99. All three smash clay like a pi$$ed off Italian wife smashes dishes!
