Jeez this post is filled with terribad to begin with. I take english isn't your first language. That's fine.
If you want to get darts, follow this guide here and get some good darts.
So, from my understanding your host supplies your darts and they are bad. I don't know if they're required for use, or dart type, quality and fit. Particularly the problem seems to be that the darts are bad quality, and those aren't good for springers. I reccomend (even thought I HATE flywheels) is to get a stryfe (or whatever flywheel of your choice) and use that as a decent primary. That may fix your problem. Otherwise, try using a strongorm or another cylinder blaster (like a hammer shot) as they do decent with darts of all kind.
Sorry about my English. I am really tired(also it is my first language but i am behind in grammar and things like that) Thanks alot for all the help. If i had good darts would the rampage be a good option?
