Wolverine STORM InGrip Regulator

Wolverine STORM InGrip Regulator:

The second piece of the STORM Regulator saga is a version that can be mounted in the grip of standard M4 guns. Moving the regulator closer to the gun results in an even faster recharge rate and the ability to effectively use C02! C02 is a less-expensive alternative to HPA and provides approximately 3x more shots per tank.
