No love any more for the Pulsar? Is it too 'old' a design? I've got 2 of them - HP in .177 and standard power in .22. And thanks to AOA's 'pre-owned' drop this week, Pulsar #3 (HP in .25 cal) will be heading my way very soon. Pretty incredible 'pups in my experience - reliable, pellet-on-pellet accuracy, lots of shots for a smaller air reservoir, best trigger I have ever used in a bullpup, and it is so convenient to be able to be able adjust power levels so easily in the field using the in-built electronics. But yes, as everyone knows, they are pretty heavy.
But another one I would look at would be the Uragan. Regular length, or mini if you want to go really compact. Tons of shots per fill, accurate and built like tanks.
