22 caliber adjustable pin probe with .25 caliber sleeve
Light valve return spring - allows valve to stay open longer
Rubber Ball to prevent the light spring from over compression
Two hammer weight spacers - more hammer spring compression and added hammer weight means regulator can be opened at high pressures
Please Note: When installing this kit on an Impact M3, the light spring and rubber ball are not to be used.
** Only to be used with a bridged/slug transfer port**
