After recent field testing, the indexing mechanism has been redesigned to withstand a larger recoil.
The pin locking assembly has been replace by a more rigid retractable pin that pins directly into the side plate, reducing the risk of damage from the recoil of a heavier percussion charge.
This change was instituted for our professional pyrotechnics customers. The performance will still be the same, and the experience will be still be amazing.
