Do you want your Spyder or Spyder Clone to shoot and recoil like a high-end marker. No more erratic grouping from excessive recoil. Reduces kick and sound noticeably.Large volumizer for better recocking. Hardened steel for maximum wear resistance.Nylatron GS sleeved striker for Spyders using the slim striker. Weighing in at 33 grams, its half the weight of a stock striker and my personal choice of strikers. Spring kits are necessary to tune the Nightstriker in. The Nightstriker is not a drop in upgrade it needs tuning.
The Insane Pain Sports Nightstriker is older, so while it may be available used and in a few cases new, it is not commonly available anymore.
