This short-action One Shot Sled is compatible with the Glenfield Model A Rifle. This polymer flush-fit sled allows only a single round to be loaded into the rifle and provides smooth single-round feeding. It is 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. 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. The sled is installed in place of a magazine and is compatible with short-action rifles in several calibers including the 350 Legend 450 Bushmaster 308 Win 243 Win and 6.5mm Creedmoor. This package includes the following components: (1) sled; (1) magazine well; (2) action screws and (1) 3/16'' Allen wrench. This Genuine Glenfield Factory Accessory is made in the USA.
