Introduction: Knex Full Auto V5
This is my upgraded full auto as you may have seen in one of my forum topic.
V1: Super Basic with weak structure but full auto.
V2: Made a stronger fake barrel.
V3: Added strength to structure.
V4: Reduced thickness and bulkyness to a 5 layer design
V5: Redesigned whole gun, mechanism is the same but the whole structure is different.
