  • Terry from Canada asked:

    Why is it such an issue to have the actual physical dimensions (length and diameter) taken for this item and posted in inches with the product discription? There are literally dozens of older model air rifles that these pistons could fit.

    • David from USA:

      OD is .96 inches, ID is .78 inches, and Length is 5.62 inches

  • Terry from Canada asked:

    What is the diameter and length of the metal piston?
