Umarex notos/carm magazine question…..

I agree. If you use a focus wheel it is almost 100% required that you have R/H mags! I think that was the main reason that Carm decided to offer them. A second thought is to keep in mind that the larger Carm mags are tall! You may have to use higher risers on your scope rings to move the barrel or larger parts of your scope higher to clear them when inserted. Carm mags are so much better quality and it justifies all these changes.
