This Power Kit will bring the "Max" out of your HP Max. For all of those who have purchased a version with limited power and want to travel somewhere where there are no restrictions or have finally got the license that would allow them to use it, this kit will get you there. It consists of the full power transfer port ring and an extra plug to cover the atmospheric hole in the air tube once the regulator is removed.
NOTE that: for calibers .30 and .35 only the full power transfer port ring is included. The plug is not needed for these calibers. For the .45 and .50 caliber both the full power transfer port ring and the extra plug are included.
