O.O Always. always, always remove the inner barrel from the gun before cleaning it! Also, don't use paper towels. Use a cotton tshirt cut into patches or something similar.
First remove the inner barrel, disassemble the hop up and remove the bucking and clean everything thoroughly. Reassemble making sure that that the bucking is seated properly on the barrel and that you get the nub back in the right spot. check it by dialing the hop on and look through the barrel, the two fins should be protruding down into the barrel evenly. Try that as see if anything changes..

Paper towels are ok to use if you have no other choice but it can scratch the inner barrel when used dry and also leave lint/fiber inside of the barrel (depending on the quality of the paper towel).

Note: You can clean you barrel without removing the hop-up so long as:
- The hop-up is off
- You stop the rod before the hop-up chamber

.22 caliber/5.56mm cleaning patches are pefect.
I've tried aftermarket buckings but the KWA give me the most reliable performance.
Several small parts to lose so find one of the Youtube videos on the process.

Cleaning the barrel seemed to improve performance a lot. I can hit a man sized target at around 150 feet pretty accurately. While this isn't the largest range I could be getting, I feel as if my "bad aim" and general newness to airsoft rifles is causing range to drop, basically I'm not aiming accurately enough. Thanks for all the help and tips, I'll be sure to use them in the future!

After cleaning bench rest the gun to determing inherent accuracy. Rest it on sandbags (which I'll bet none of us have) or something equally stable. 50 feet is a good starting rang. Hop up Off. Add one (1) click mark at a time (BBs are cheap). Different mass BBs make a difference. My KM4-CQB likes 0.28g BBs (Elite Force biodegradeable). This will eliminate you from the accuracy matrix.
