I have to wonder if you guys are talking about the original RSM or the revised model they brought out ca. 1999.

The differences are:
Original (RSM #1) 24" HEAVY bbl, front swivel on stock, weight ~ 10.75 lbs in 416.
Revised (RSM#2) 23" Slimmer bbl, front swivel on barrel band, weight ~9.75 in 416.

While weight of the newer 416 is much more in line with my idea of a 416, the balance is still atrociously front heavy.
