Recently picked up a kral knight/nemesis and sighted it in at 25 yards and shoots great so far but my mind is always going and wondering what I can do to make it better gauge replacement tweaks mods etc. I have the .25 and it had a real bark so added my sumo to it is the sumo a good option or should I get a different. I know its very similar to the jumbo so any info would be greatly appreciated. Should I add a regulator and a carbon bottle anything to make this my top shooter until I get the funds for a higher end.
