Prevents backing out or movement of the hammer spring adjuster by using the Brass Jam Plate
Never again strip out your FX Airgun Hammer Spring Adjuster due to Loctite!!
Set your adjuster where you want it, then install this Brass Jam Plate behind hammer spring adjusters found on models such as the FX Streamline, FX Dreamline Classic, FX Wildcat MKI, MKII, FX Royale and FX Boss. Does not affect the setting of your adjuster, as your adjuster requires a 5mm allen, whereas this plate only fits a 4mm allen. Also, will not strip out and will not seize.
