You are most welcome smile
I agree, I see no reason for this happening.
With the barrels off, the forend mates up well to the receiver
With the barrel on, the forend has a gap that can not be compessed.

I am at a loss with one exception. JUST A GUESS!!
That being, the forend barrel lug came off and was re-soldered in the wrong location,
and with the V of the banjo lug holding the forend out.

And since the forend is not tight to the barrels the lug may also have been repositioned too high also.



Tough to figure out what to show and get the light right
