With the arrival of the CROSMAN 2240XL I'm interested in a Rat Catcher again with the availability of the 5 &10 Shot magazines, shoulder stock, and I presume the high pressure air conversion previously available will still work, plus an 18/ 20" barrel threaded for moderators. Availability of open sights or red dot or scope. The custom shop used to sell the rat catcher, it would be great if crosman would offer it again with all of the above options as Co2 or high pressure air, open sight or pic rail, rifle barrels in 3 lengths with 12x 20 thread. I thought I saw an after market fiber air tank with regulator to supply the correct air pressure to the 2250. What do you think, have you noticed any other options?
