The Ruger One-Shot sled is a new accessory for short-action Ruger American rifles. Used in place of the Ruger American magazine"" the One-Shot sled allows for quick and easy loading of a single cartridge. The sled provides smooth"" single-round feeding"" useful to slow down a new shooter or simplify loading during range sessions. The Ruger One-Shot is also ideal for hunting - particularly in states with single-shot hunting regulations"" such as Illinois. The Ruger One-Shot is a direct magazine replacement for Ruger American rifles in short-action calibers"" including many calibers used for hunting (350 Legend"" 450 Bushmaster"" 300 Blackout"" .308 Winchester"" 6.5 Creedmoor"" etc.). The sled ships with a magazine well to adapt rifles configured from the factory to accept AR-"" AI-"" or Mini Thirty -pattern magazines. When inserted in the rifle"" the One-Shot sled fits flush with the stock and does not interfere when carrying a slung rifle or shooting from a bag or backpack.
