Extreme Shock End Caps
With the replacement of the dual-loop cross-lock system and the start of the EZ-Coil standard came a need for a new system standard. Due to the design of the EZ-Coil, Extreme Shock End Caps (ESEC), which were optional before, are now a must. Today, all styles of Firenocks come with ESECs and ESEC installation tools. Extreme Shock End Caps, after years of testing, have proven again and again that they are truly the best insurance policy you can have for both normal and crossbow arrows for any speed or terms.
