Which is still a bunch of crap. One may make:

A. Trigger Plate Action
B. Boxlock

With A., the lockwork is attached to the trigger plate, and comes free with it when the trigger plate is removed.

With B., the triggers may be part of a floor plate, but the locks are mounted inside the frame.

TWO distinct, seperate, designs.

A Remington 1100 is a 'Trigger Plate Action'. It sells for less than $30,000.
