How close is the CFX barrel to the BSA? I'm beginning to think Gamo just took the barrels from the BSA for their CFX, literally, when they merged to two companies. Why else have a dovetailed sight when you can't drift it? Anyone know if the latching mechanism is the same? Seen a really nice steel shroud for the BSA underlever and wondered if it would fit a CFX? Just not a big fan of that factory shroud, plus would be nice to put something like a globe sight on a CFX.
