The new "Necked Down" Plenum Extender 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.
The “Necked Down” plenum has been designed to accommodate the RAW wood laminate LRT stock as well as the available aftermarket options.
- Adds 3.69” to the length the tank protrudes away from the receiver.
- Can have the volume further augmented with the 20cc extension
- Designed to fit the RAW wood laminate LRT stock as well as other aftermarket chassis.
*Note: this Plenum will not fit RAW HM1000x rifles with the integrated moderator.
