I have a Kral Puncher Knight (nemesis) that came from the factory in .22 cal. I bought the .25 barrel/probe upgrade kit and have failed miserably at installing it. After multiple attempts it seems like I cannot ever get it "straight" ... it shoots so extremely low/right it's impossible to even try to shoot safely. Any advice on a way to fix it ... or should I post a "WTS half working kral puncher knight that comes with a pile of .22 and .25 parts"? Or is there someone here who does repairs/service that might be interested in servicing my money pit?
