Over the past decade, players have found that correctly boring their barrel to the size of the paintballs they are using leads to significant increases in both accuracy and efficiency.

Much to everyone's surprise, paintballs aren't all made to be .688 anymore. Paintballs have become progressively smaller over the years. The control bore inserts needed to size this smaller paint have not been available...until the iFIT Kit.

The iFIT Control Bore Sizes Range from .667 up to .692

If you have more than one gun, and they take different barrel threads that you can easily use the kit on both guns by just adding the needed barrel adaptor for just $39. No other barrel boring kit makes it that affordable to switch from one gun to another.

To the left you can see the .676 bore insert combined with the barrel adaptor with "Autococker Threads".

This kit includes the TIPX Thread Adaptor and 6 Control Bore Inserts. It does not include the shortened barrel like some of our other kits.

This kit requires that you use the stock barrel and it will stick out an extra 1.75"
