I asked this in the Rifles, Uppers, Lowers, Barrels sub-forum and got zero replies so hope you guys can offer suggestions here.
Hope the title makes sense. I'd like to completely cover the side sections between the picatinny rail sections with the panel pieces. Doesn't look like it's possible given the two panel sizes available are 5.5" and 4".
If my suspicions are true and KAC doesn't offer panels in sizes to accomplish this is it possible to;
(1) add one of the 3" 8 rib pic rail pieces then a 4" standard panel
(2) modify a couple of the standard panels (cut & machine new mounting holes)
