Is not a standalone item, the extender only functions when connected to RAW Full Sized Plenum Extender or RAW Necked Down Plenum Extender.

The new Plenum Extender Extension is designed to increase the power and performance of the
HM1000X without the need to adjust the gun’s regulator. For an HM1000X in .22 caliber it can bring the power of the rifle when using slugs up to a level on par with .22LR. It does this by increasing the volume of regulated air available to the gun on each shot. This allows for more power each shot as the greater amount of air pushes the projectile faster and harder, without needing a higher regulator pressure.

·Adds 1.81” to the length the tank protrudes away from the receiver.
·Is not a standalone item, the extender only functions when connected to a Plenum Extender.
·Multiple Plenum Extender extensions can be installed at once to further augment the volume beyond the initial increase. (e.g. installing two with a 45cc plenum will add 85cc’s total.)
