AGM L96- Upgrades?

I bought my AGM L96(the newer version, MP002 i believe) an di plan on upgrading. i am unemployed, so i wanna get something that will help withthe accuracy of my gun, the groupings arent so great, and i am taking into consideration that this is airsoft. so, a barrel? and if so, any links to a well- priced one?
and if its compadable with, say, a well or UTG bolt(not an unrealistic AGM one, that i hate by the way)? i would love to have an ACTUAL L96 bolt.

so, any suggestions?
