You are looking for increasing your effective range. i.e. you want to reliably hit something further out than you can now.

1. BB Weight (Free, sort of...since you're going to shoot BBs anyways)
You've got to be using 0.25g BBs at a minimum to get any kind of consistency at distance. 0.28/0.30 are really nice too to result in a more predictable shot pattern.

2. Hopup rubber (almost free, easy to swap, can be frustrating to find the right match)
They're so cheap and relatively easy to swap out. Make sure it's not torn, scratched, oily. Clean and consistent. Love the guarder clears...other guys prefer something else. Try LOTS of different ones...spend some time fine tuning the hopup. You'll hit a sweet spot with the BBs you're using with the rubber and the power level. Make sure your nub is long enough and isn't mishapened. Try a harder or softer nub with a given rubber.

3. (FREE, PITA) Keep your barrel and bbs clean, free of water, oil, grit, etc... That goes for your muzzle and all the dust/dirt/crap in your gun case too.

4. (can be free...takes some effort and attention on your part) Shot to shot FPS consistency....if your rifle is swinging 20+ FPS between shots....forget buying anything. Grab a screwdriver and fix the compression/airseal of your rifle.

5. Tightbore ($35-100+, easy to install). 6.04-6.03mm...keep it matched with your cylinder

6. FPS ($10-20, easy to swap). If you're expecting a 300fps tuned rifle to shoot as far as somone with at tuned 395fps rifle...you're going to be disappointed.

7. Sights (easy, can be expensive). Your sights must be capable of fine enough resolution so that you can place your shots on target. The sight system + rifle must be able to consistenly hit where aimed (at closer range)...to expect hits further out.

8. You (Free, not easy). Your shooting stance/postion/aim/etc....might not be conducive to accurate shooting. It ain't rocket science but I've seen some guys where it's be a pipe dream if they ever hit anything they were aimin at.
