It does look better with a "bull barrel" design. That being said, look at those paltry energy levels! I hope that's a misprint, but if they're planning on releasing a .25 caliber version with only 28 ft/lbs of energy, then just skip that caliber. I'm getting 27 ft/lbs with my first generation .22 caliber Compatto. I never understood the reasoning behind British made rifles like Air Arms, Brocock, and even some Daystate models with .25 caliber options but power output in FAC only slightly better than a .22. If you're going to go, go all out and make it a 35-50 ft/lb version. I never considered an Air Arms S510 in .25 caliber simply due to it's low energy output for such a caliber.
