Improved version! Does not fit older models of Autococker (pre 2000). Made up of stainless steel components and featuring an external adjusting tool (not included) which allows velocity adjustment without removing the cocking rod and an O-ring friction adjusting sleeve to prevent velocity drift and variation. It also gives the user a wider range of adjustment. External trigger lug adjustment is also attainable with proper access hole modification. Lightened spring is provided to increase air efficiency while aiding in preventing ball pinching.
