RA-Tech EVO II Hop-up and barrel set for Kriss Vector
Review by
I was a bit unsure on weather i should buy this for my kriss vector, as with the stock barrel and hop it seems ok. i was wrong. i put this thing in and it goes twice the distance with triple the accuracy. bit of a tricky install though, you have to take the entire barrel out of the vector, and put a tiny cap thing from the origonal barrel on this one, it all fits fine (apart from it might need some wiggling in)
