upgrade for HK 417 GBB
 

Hi, I just bought a VFC HK 417 GBB. I noticed the aim could be improved. So I want to buy and inner barrel. What brand do u guys recommend? what size?

What other upgrades would you recommend for this gun? (money is not an issue)

grab the maple leaf hopup and a orga barrel, steel buffer and steonger spring. get mag springs for the mag mod, thats about it
