A-Zoom's StrikerCap buffer cartridges are the best choice for safety training, bump testing and dry practice. The rugged design has been 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 the magazine or manually repeating the slide/bolt. In addition, the buffer cartridge has an O-ring that ensures it is centered and stays in the barrel. In the place of the primer there is a hard-wearing plastic insert that protects the firing pin when the trigger is released.
