Michael64,
It's on this page about 1/2 down:
12ga Tactical strippers
Look for "Choate conv kit 6rd only um84 molle compatible
CCK2" $14.00 "converts old Choate speed strippers to my UM84 ss belt clip includes lexan spacer, CAN ALSO RETROFIT 2 1/4"SS BELT CLIP molle compatible "
That web page leaves allot to be desired, but once you find them, it works well to order from.
