Here's the deal. I installed Guarder hopup sleeve on my AK couple of hours ago because TM one developed a hole in it during last game. Used KSC .2s to test fire the gun. No backspin whatsoever. BBs would have the same trajectory at any hopup setting. I tried several different things including some of left over TM .25s. For some reason .25s work perfect... Good range and normal backspin effect.
Any idea what's going on? I'm totally confused here. Used same KSC bb's with my other AEGs/Guarder hopup sleeve and everything worked well except for double feeds every now and than. I think even this same AK used to have Guarder sleeve on it back in the day.
Btw, this AEG shoots around 395-400FPS.
