Per SMGLee info :
there is still plenty of those 553 being checked out. ask the armory chief and he heard hothing in regards to the lever or any mounting issue...Only Aimpoint I seen are in the BUDs armory....seen like most of the front line guns are equipped with the 553 nowadays...
Still no signs of any Daniel Defense RIS2 in inventory....plenty of KAC RAS with Colt M4 SOCOM H-Bar give to the Teams via SOCOM.
Another interesting trend I notice is the move from ACOG ECOS to the Elcans DRs for the carbines...
