This one is rather tricky. The connectors for the Gunbarrel will be different from the Real Grade connectors.Â
OPTION 1
I will suggest that you cut the connector from both kits, and combine both to make it compatible to Real Grade Strike Gundam.
OPTION 2
You can also just glue the Aile Striker connector to the gunbarrel striker, if you don't want to transform it into standard mobile armor mode.

This recipe works perfectly without any modifications on HG 1/144 Aile Strike Gundam
