You can turn your air pistol into a small rifle easily and quickly. You only have two screws that you have to loosen to mount the gun stock. You can switch between pistol and pistol carbine that quickly. Even with the stock attached, the pistol remains nice and compact and easy to carry. Higher precision is thus very easy to achieve. You have the option of buying the carbine stock either with an adjustable cheek piece, or if you want to continue shooting via the open sights you can save yourself a few more bucks and opt for a fixed cheek piece.
