Hello all...
Does anyone know the inside diameter of the Benjamin Bulldog transfer port sleeve?
Also, does anyone know the rifling twist of the Benjamin Bulldog barrel?
Thanks in advance!

The twist is 14", be much better if it was 20". The plastic sleeve is about .250 or so, if you are increasing port sizes, just leave it out. Mine didn't have one, just the later ones. Regards, Tom

I measured the one I got from crosman parts.
