Abstract: A pre-charged pneumatic air rifle air tank adapter lowers an air tank relative to the pre-charged pneumatic air rifle. The lowered air tank facilitates aiming. The adapter also provides a substrate for mounting accessories including a quick disconnect refill plug and a pressure gauge. The adapter includes a female rifle fitting with a threaded central conduit, a male air tank fitting with a central conduit and external threads parallel to, coplanar with and about 0.75 to 1.5 inches apart in elevation from the central conduit of the female rifle fitting, measured vertically from centerline to centerline. A body of the adapter has an internal conduit extending from the female rifle fitting to the male air tank fitting.
