They will fit on yours, easily because of the handguard is railed. They fit on my 6920MP-B but not while letting me keep my BUIS mounted, to do that I'll have to change out to a DD Omega handguard, and slide everything forward about an inch, all in all a better choice anyway, as the red dot acts like the front sight. At that point, with everything set right, I'll be looking through my rear sight, through the magnifier, at the red dot on my front sight post holding on the target. In theory anyway, better shots would probably do it better than I.
