This back-bottle style Internal Air ASA fits the Vortex platform and pairs with the Vortex lower/trigger frame. It lowers the bottle or stock down by 1 inch from the bore axis of the marker to give better clear of viewing to improve aiming while wearing your mask.
**When using Tank in Stock you will need the Hinge/Swivel Guide Rod**
**This part is a replacement part and does not offer rear air capability without the Flexi Air Kit installed**
