The rifle assembly further includes a rifle butt stock having a front portion and a butt stock adapter having a rear portion removably secured to the butt stock front portion and a front portion removably secured to the central chassis front portion. ## Claims ### Claim 1 A rifle assembly comprising: a central chassis having a longitudinal axis and carrying an action including a trigger, a trigger guard and a pistol grip having an upper portion with an unobstructed palm swell longitudinally rear of the trigger, the central chassis having a rearward-facing projection extending longitudinally therefrom above the unobstructed palm swell of the pistol grip; a butt stock having a front portion with a forward-facing projection; and an adapter having a forward-facing projection abutting the central chassis rearward-facing projection and removably secured thereto, and a rearward-facing projection extending longitudinally therefrom, one of the adapter rearward-facing projection and the butt stock projection having a fork with vertically spaced brackets above and below the other of the butt stock projection and adapter rearward-facing projection and removably secured thereto, the adapter rearward-facing projection and the butt stock forward-facing projection being disposed entirely longitudinally rearward and above the upper portion of the pistol grip and trigger to create an unobstructed palm swell longitudinally rearward of the upper portion of the pistol grip and trigger. ### Claim 2 (depends on 1) The rifle assembly of claim 1 wherein the adapter has a rearward-facing fork with vertically spaced brackets above and below the butt stock projection. ### Claim 3 (depends on 2) The rifle assembly of claim 2 wherein the forward-facing projection of the butt stock has flanges on at least one side of the brackets of the rearward-facing fork of the adapter. ### Claim 4 (depends on 2) The rifle assembly of claim 2 wherein the forward-facing projection of the butt stock has upwardly- and downwardly-projecting flanges on opposite sides of the brackets of the rearward-facing fork of the adapter. ### Claim 5 (depends on 4) The rifle assembly of claim 4 wherein the butt stock forward-facing projection flanges form slots into which are slideable the brackets of the adapter rearward-facing fork. ### Claim 6 (depends on 4) The rifle assembly of claim 4 further including at least one removable fastener disposed between the butt stock forward-facing projection flanges and the brackets of the adapter rearward-facing fork. ### Claim 7 (depends on 1) The rifle assembly of claim 1 wherein one of the adapter forward-facing projection and the central chassis rearward-facing projection has a slot and the other of the central chassis rearward-facing projection and the adapter forward-facing projection has a flange slideable within the slot. ### Claim 8 (depends on 1) The rifle assembly of claim 1 wherein the adapter forward-facing projection has a slot and the central chassis rearward-facing projection has a flange slideable within the slot. ### Claim 9 (depends on 8) The rifle assembly of claim 8 further including at least one removable fastener disposed between the central chassis rearward-facing projection slot and the adapter forward-facing projection flange. ### Claim 10 A rifle assembly comprising: a central chassis having a longitudinal axis and carrying an action including a trigger, a trigger guard and a pistol grip having an upper portion with an unobstructed palm swell longitudinally rear of the trigger, the central chassis having a rearward-facing projection extending longitudinally therefrom above the unobstructed palm swell of the pistol grip; a butt stock having a front portion with a forward-facing projection; and an adapter having a forward-facing projection abutting the central chassis rearward-facing projection and removably secured thereto, and a rearward-facing projection extending longitudinally therefrom, one of the adapter forward-facing projection and the central chassis rearward-facing projection having a slot extending longitudinally and the other of the central chassis rearward-facing projection and the adapter forward-facing projection having a flange extending longitudinally and slideable within the slot, one of the adapter rearward-facing projection and the butt stock projection having a fork with vertically spaced brackets above and below the other of the butt stock projection and adapter rearward-facing projection and removably secured thereto, the adapter rearward-facing projection and the butt stock forward-facing projection being disposed entirely longitudinally rearward and above the upper portion of the pistol grip and trigger to create an unobstructed palm swell longitudinally rearward of the upper portion of the pistol grip and trigger. ### Claim 11 (depends on 10) The rifle assembly of claim 10 wherein the adapter has a rearward-facing fork with vertically spaced brackets above and below the butt stock projection. ### Claim 12 (depends on 11) The rifle assembly of claim 11 wherein the forward-facing projection of the butt stock has flanges on at least one side of the brackets of the rearward-facing fork of the adapter. ### Claim 13 (depends on 11) The rifle assembly of claim 11 wherein the forward-facing projection of the butt stock has upwardly- and downwardly-projecting flanges on opposite sides of the brackets of the rearward-facing fork of the adapter. ### Claim 14 (depends on 13) The rifle assembly of claim 13 wherein the butt stock forward-facing projection flanges form slots into which are slideable the brackets of the adapter rearward-facing fork. ### Claim 15 (depends on 13) The rifle assembly of claim 13 further including at least one removable fastener disposed between the butt stock forward-facing projection flanges and the brackets of the adapter rearward-facing fork. ### Claim 16 (depends on 10) The rifle assembly of claim 10 wherein the adapter forward-facing projection has a slot and the central chassis rearward-facing projection has a flange slideable within the slot. ### Claim 17 (depends on 16) The rifle assembly of claim 16 further including at least one removable fastener disposed between the central chassis rearward-facing projection slot and the adapter forward-facing projection flange. ### Claim 18 (depends on 10) The rifle assembly of claim 10 wherein the adapter has a forward-facing projection abutting a top portion of the central chassis rearward-facing projection.
