My 28" barreled RBL-12 which weighs exactly 7 pounds ( BTFE, SS ) with the thinner pad on the interchangable pad system measures 2 1/8 inches ( 54 millimeters ) from outside the breechballs and just shy of 1 3/32 of an inch between firing pins. With a splinter FE and a regular butt-plate (i.e., no interchange system) I am fairly certain the weight could be down close to 6 1/2 pounds. FWIW.
