Collection: GBBR (Gas Blow Back Rifle)

GBB is short for “Gas Blow Back” and just means the system will propel a BB as it cycles a slide/bolt which then loads the next shot. You can break down a single shot as such: once the TRIGGER is pulled, compressed gas is released from the MAGAZINE, flows through the HOP UP UNIT, and pushes the BB out of the INNER BARREL. The same gas from the shot is used to push the SLIDE back, and the RECOIL SPRING drives it forward while the NOZZLE loads the next BB into the HOP UP. Like with my previous explanation of AEGs, there are additional parts involved, but this is the simplest breakdown to create a good foundation.
