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.
