Description
Discovery power adjuster allows you to adjust the pre-load on the hammer spring to tune for different power levels and greater efficiency, and is a drop in replacement for the standard discovery end cap. In a stock .22 disco you can expect an adjustment range of 16-28fpe with 14.3gr pellets.
Or if paired with our Medium Discovery spring, you can expect an adjustment range of 3-27fpe with 14.3gr pellets.
