As I can tell by experience the Magpul XT panels interefere with the Larue QD sling attachments in a 7.0 rail system (I know it can be cut/modified but I dont want to).
Does KAC panels fit other rail systems other than KAC? If so, which size (11, 9, 6 ribs) fits left and right sides of a Larue 7.0 without the need to be modified?
KAC panels also interfere with the QD mount on the LT handguards.
Your pic shows a locking tab - many railed handguards have cutouts on the first and last rail positions; the tab “grabs” these cutouts and prevents the panel from moving around.
You want an 11-rib panel for the LT 7.0 if you want a single panel to cover the whole rail.
