I found a bunch of 2mm ball bearings & the fit perfect. There $1each online You can get a set of twelve high grade from HPI racing for about $3
If you drop one on the floor, dont bother looking for it. Change this on a work bench over a Towel
The new bucking & bearing work great, the gun shoots as far as the M9 But, its NO M9
these are the my Balls
