Below is from another post, but the answer is a magnum exists, it's not a 983 anymore.
"Curiosity got me on the 22's.. out of the following:
XT-22 has 15 rifles, 11 plastic and 2 hardwood, 1 laminate and 1 walnut.
XT-17 showed 9 rifles, 3 plastic, 2 hardwood, and 4 laminate
XT-22Y shows 4 rifles, 2 hardwood and 2 plastic.
That's 28 .22 caliber rifles and only 1 is Walnut! It's a .22 WMR, XT-22MTW...whatever that means. I say lets take a simple concept and screw it up, while we're at it throw in some funny impressive names ...hell, that'll sell them plastic jobbies!"
