Hey, these are nothing but 25MM grenade launchers with integrated laser range finders (LRF). I thought they were some kind of new assault rifles which they are not. Basically air bursting grenades. I like the way the LRF automatically sets the range on the grenade fuse leaving the firer with nothing to do. Ranges are commensurate with those of automatic grenade launchers. The problem with this as with all other kinds of automatic launchers is that one can't predict the damage done with any degree of certainty and so the danger and therefore the need for caution will remain as the attacker approaches the objective.
All snipers worth their salt change positions after firing and that will negate the utility of this weapon. Also air bursting anti-personnel grenades are indiscriminate and may result in collateral damage. Not sure if it fires bursts though. Bursts of two to three rounds/grenades will make it very handy indeed.
On the whole, its sighting system makes it unique, other than that, it is just another automatic grenade launcher.
