RA-tech WA hop up rubber (red) will boost the range alot, Also use .25's-.30's BB's. I would say get a new inner barrel but im not sure on the quality of the KA barrel.

I would also check the compression on the loading nozzle. (to do this take the bolt out and pull the nozzle forwards and cover the inlet and outlet and then push down, If it goes straight down with out any issue then you need to fiddle with the O-ring to make it abit tighter to increase the compression, If it goes down with abit of force and you can hear the air escaping then its pretty good. But if it requires alot of force to be pushed down then you need to find a smaller Oring)

I would also say get a G&P plastic loading nozzle, They are the best on the market
