This assembly provides the ability to control spring tension pre-load, and the Spring Stop Point (Ability to tune with or without Hammer free-flight). This Assembly still allows access to the Hammer Striker screw adjustment as well! By replacing the 4mm Allen drive Striker with a 3mm Allen drive Striker (included with the kit) - 3mm Allen drive fits through the spring tension adjuster to access Striker. This assembly provides one more layer of easy access fine tuning to your shot speed from the back of your Raptor.
This Kit also works with our Marauder TSS kit.
