Rifle adapter assembly

A rifle adapter system for converting a rifle having a rifle receiver to fire ammunition other than for which it was designed to fire, said adapter system comprising:

• an adapter magazine attachable to said rifle for conveying adapter cartridges to said rifle receiver, said magazine having feed lips extending approximately the length of an adapter cartridge and an angularly disposed integral ramp extending forwardly therefrom, with side guides adjacent said ramp to guide said adapter cartridges when moved forwardly to battery position,
• an assembly having a rear retainer and forward adapter chamber held in fixed spaced relationship by a bolt supporting means,
• a bolt slidably moveable along said supporting means and between said retainer and said adapter chamber,
• said bolt having means thereon for moving an adapter cartridge into said chamber and extract the casing after said adapter cartridge has been fired,
• said bolt having a firing pin slidably mounted thereon for striking said adapter cartridge when in said chamber to fire the same,
• spring means on said bolt supporting means urging said bolt forwardly to a battery position,
• said rifle having a hammer and trigger for searing said hammer in cocked position,
• said bolt being operable on recoil to move said hammer to said cocked position,
• said hammer, bolt and magazine being so positioned, arranged and disposed that said bolt cocks said hammer on recoil before recoiling back far enough to feed a fresh adapter cartridge toward said chamber as said bolt advances to said battery position and thereby prevent double firing.
