stalkingbear,do they make a 30mm tube in the FFII's or do you have to buy the signature series to 30mm tube,one of my biggest qeustions was also on the light transmission,I wanted yo buy the FFII in the 3x9x50mm with a 1inch. tube,I was told the 50mm with one in. tube would only let in the light capacity of a 44mm with a 1in. tube I was told to get the full performance out of the 50mm I needed to get the 30mm tube but the price goes way higher to get the 30mm tube that was one of the qeustions of the 4200 being a better scope because it had the 30mm tube.
