If it were fired from a lightweight launcher a case could be made for it having higher recoil than Rcl 3, but it's an underslung weapon so the total weapon system's weight is going to be 3.5+ pounds, and Rcl 3 seems reasonable (that the rules say you can mount it on a heavy pistol possibly not so much).

Throwing a 25mm grenade 2,000 yards is ambitious but doable. The russian AGS-17 can do it, though it weighs over 60 lbs. The OICW program wanted to do it in a man-portable fashion, but never made it out the prototype phase, citing weight as one of the primary obstacles in continuing the project.

I think a man portable grenade launcher that can get 2,000 yards of range on a 25mm grenade is quite doable. I just think it should weigh 6 lbs or more.
