Convert your Diana Stormrider/ to 25 caliber. Breech not included, so you will have to drill your breech with a 9/32 drill bit in order to make it compatible with the .25 barrel. This is done by drilling the front face loading area on the breech.
Comes with a maple products 7 shot magazine and single shot tray and 19″ barrel, and the 25 cal pellet probe. The 19″ barrels have the stock m10 threads and will come with a front sight and thread cap, or you can add a m10 muzzle brake or 1/2×20 thread adapter instead of the thread cap. All barrels will come with the front sight.
