Abstract
A firearm assembly includes a stock and an action secured to the stock. The action includes a receiver, a barrel, and a recoil lug that is positionable adjacent a bearing seat of the stock. Various fastener assemblies are provided to assemble the action to the stock with the recoil lug firmly seated against the bearing seat, thus providing longitudinal and torsional stability to the firearm assembly. There is further provided a stock having a bedding portion that includes a surface forming a channel in the bedding block. Either the channel or the receiver includes a number of ribs extending therefrom that support the receiver in the bedding channel when the action is secured to the stock. There is also provided a stock having an action mounting insert. A compressible member is provided between the action mounting insert and the stock.
Claims41
A firearm assembly, comprising:
- a barrel having a forward end and a rearward end;
- a receiver coupled to the rearward end of said barrel, the firearm assembly having a longitudinal axis extending along the center of said barrel;
- a stock including an action mounting portion, said action mounting portion including a bedding block having an upper surface forming a bedding channel with opposite sides, said bedding channel extending in the direction of the longitudinal axis;
- and
- a pair of ribs, each one of said pair of ribs extending along one of said sides of said channel, said pair of ribs supporting said receiver in said bedding channel when said receiver is mounted on said stock.
2 more elements
The firearm assembly of claim 3, wherein said receiver is initially supported in said bedding channel by said pair of ribs such that a gap is formed between said receiver and said pair of lower ribs, and further comprising a bedding fastener extending through an opening in said bedding block and into a passage formed in said receiver, whereby said bedding fastener secures said receiver in said bedding channel with said receiver in contact with said pair of lower ribs.
A firearm assembly, comprising:
- a stock including an action mounting portion including a bedding block having a forward face forming a bearing seat, a forward block positioned forwardly of said bedding block, and a groove between said bedding block and said forward block;
- a barrel having a forward end and a rearward end;
- a receiver coupled to the rearward end of said barrel, the firearm assembly having a longitudinal axis extending along the center of said barrel and further including a recoil lug between said receiver and said barrel, said recoil lug having a portion extending downwardly from said barrel and received in said groove, said downwardly extending portion of said recoil lug having a rearward face positionable adjacent said bearing seat when said receiver is placed on said action mounting portion of said.stock;
- a fastener assembly arranged to contact a forward face of said recoil lug and apply rearwardly directed pre-load against said forward face of said recoil lug to secure said recoil lug against said bearing seat, wherein said fastener assembly includes a wedge positionable in said groove between said downwardly extending portion of said recoil lug and said forward block, said wedge having a threaded passage formed therein and a fastener extending through a hole formed in said action mounting portion transversely to the longitudinal axis, said fastener being positionable in said threaded passage of said wedge to draw said wedge downwardly along a can surface on a rearward face of said forward block to thereby displace said wedge rearwardly against said forward face of said recoil lug.
1 more element
A firearm assembly, comprising:
- a stock including an action mounting portion having a bearing seat formed thereon;
- a barrel having a forward end and a rearward end;
- a receiver coupled to the rearward end of said barrel, the firearm assembly having a longitudinal axis extending along the center of said barrel and further including a recoil lug between said receiver and said barrel, said recoil lug having a portion extending downwardly from said barrel, said downwardly extending portion of said recoil lug having a rearward face positionable adjacent said bearing seat when said receiver is placed on said action mounting portion of said stock;
- a fastener assembly arranged to contact a forward face of said recoil lug and apply rearwardly directed pre-load against said forward face of said recoil lug to secure said recoil lug against said bearing seat, wherein said fastener assembly includes a lever, said lever comprising:
- a first arm extending parallel to the longitudinal axis, said first arm having an opening receiving a fastener therethrough, said first-arm in contact with a fulcrum about which said first arm is pivotable;
- and
- a second arm extending from said first arm transversely to the longitudinal axis, said second arm including a contact surface opposite the first arm positioned adjacent said forward face of said recoil lug, wherein said fastener is operable to rotate said first arm about said fulcrum thereby displacing said first arm rearwardly against said recoil lug.
4 more elements
A firearm assembly, comprising:
- a stock including an action mounting portion having a bearing seat formed thereon, wherein said action mounting portion is an insert positionable in a receptacle formed in said stock;
- a barrel having a forward end and a rearward end;
- a receiver coupled to the rearward end of said barrel, the firearm assembly having a longitudinal axis extending along the center of said barrel and further including a recoil lug between said receiver and said barrel, said recoil lug having a portion extending downwardly from said barrel, said downwardly extending portion of said recoil lug having a rearward face positionable adjacent said bearing seat when said receiver is placed on said action mounting portion of said stock;
- and
- a fastener assembly arranged to contact a forward face of said recoil lug and apply rearwardly directed pre-load against said forward face of said recoil lug to secure said recoil lug against said bearing seat.
2 more elements
A firearm assembly, comprising:
- a stock including an action mounting portion having a bearing seat formed thereon;
- a barrel having a forward end and a rearward end;
- a receiver coupled to the rearward end of said barrel, the firearm assembly having a longitudinal axis extending along the center of said barrel and further including a recoil lug between said receiver and said barrel, said recoil lug having a portion extending downwardly from said barrel, said downwardly extending portion of said recoil lug having a rearward face positionable adjacent said bearing seat when said receiver is placed on said action mounting portion of said stock;
- a fastener assembly arranged to contact a forward face of said recoil lug and apply rearwardly directed pre-load against said forward face of said recoil lug to secure said recoil lug against said bearing seat, wherein said fastener assembly includes:
- a wedge positionable adjacent said downwardly extending portion of said recoil lug, said wedge having a threaded passage formed therein;
- and
- a fastener extending through a hole formed in said action mounting portion transversely to the longitudinal axis, said fastener being positionable in said threaded passage of said wedge to draw said wedge against said forward face of said recoil lug.
4 more elements
A firearm assembly, comprising:
- a stock including an action mounting portion having a bearing seat formed thereon;
- a barrel having a forward end and a rearward end;
- a receiver coupled to the rearward end of said barrel, the firearm assembly having a longitudinal axis extending along the center of said barrel and further including a recoil lug between said receiver and said barrel, said recoil lug having a portion extending downwardly from said barrel, said downwardly extending portion of said recoil lug having a rearward face positionable adjacent said bearing seat when said receiver is placed on said action mounting portion of said stock;
- and
