The StrikerCap buffer cartridges from A-Zoom are the best choice for safety training, functional testing and dry runs. The robust design is proven to withstand thousands of dry runs while protecting the firing pin.

The design ensures that the extractor does not remove the cartridge from the chamber. This allows you to practice constantly changing magazines or manually repeating the slide/bolt. In addition, the buffer cartridge has an O-ring that ensures centering and retention in the barrel. In place of the primer cap there is a durable plastic insert that protects the firing pin when the trigger is triggered.
