Description

FIELD

The present invention relates to firearm manufacture. More particularly, the present invention relates to a staking fixture for assembly of a firearm.

BACKGROUND

The AR15/M16 family of firearms and their derivatives, have butt stocks that are attached to the weapon by means of a tube which projects from the rear of the weapon, known as the buffer tube. The buffer tube is secured with the firearm using a castle nut. Although castle nut retains the buffer tube in proper alignment during normal operations, this is not the case if the firearm is dropped or hit against a wall. An impact may cause the castle nut to rotate and loosen the buffer tube from the firearm. This could lead to catastrophic failure of the firearm.

Accordingly, a need exists for improvements that addresses the foregoing and other related and unrelated problems in the art.

In the following description, numerous specific details are set forth to clearly describe various specific embodiments disclosed herein. One skilled in the art, however, will understand that the presently claimed invention may be practiced without all of the specific details discussed below. In other instances, well known features have not been described so as not to obscure the invention.

Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including,” “comprising,” or “having” and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Unless limited otherwise, the terms “connected,” “coupled,” and “mounted,” and variations thereof herein are used broadly and encompass direct and indirect connections, couplings, and mountings. In addition, the terms “connected” and “coupled” and variations thereof are not restricted to physical or mechanical connections or couplings.

Referring to FIG. 1, an assembled, partial view of a firearm 10 is shown according to some embodiments presently disclosed. Referring to FIG. 2, an exploded, partial view of the firearm 10 is shown according to some embodiments presently disclosed. The firearm 10 may comprise a lower receiver 15.

The lower receiver 15 comprises an upwardly extending lobe 30. According to some embodiments, the upwardly extending lobe 30 is used to mount a buttstock (not shown) to the lower receiver 15 and is used to align a receiver extension (i.e. buffer tube) 20 with a bolt carrier (not shown) housed within an upper receiver (not shown). The receiver extension 20 generally houses an action (or recoil) spring (not shown) and a buffer assembly (not shown). Upon discharge of a round, the bolt carrier within the upper receiver is driven rearward by action of the gas discharged by the firing action. The buffer assembly and the action spring dampen the kickback experienced by a user while also redirecting the firing mechanism back toward the chamber in preparation for firing another round. The buffer tube 20 comprises an external thread 75 for coupling the buffer tube 20 with the upwardly extending lobe 30.

The firearm 10 may also comprise an end plate 35 and a castle nut 40 for aligning and coupling the receiver extension 20 with the lower receiver 15. According to some embodiments presently disclosed, the end plate 35 is positioned between the lobe 30 and the castle nut 40. According to some embodiments presently disclosed, the end plate 35 is sandwiched between the lobe 30 and the castle nut 40.

According to some embodiments presently disclosed, the castle nut 40 comprises a forward end 63 and a rear end 67 (shown in FIGS. 4a-b). According to some embodiments presently disclosed, the forward end 63 of the castle nut 40 comprises a first plurality of apertures 47. According to some embodiments presently disclosed, the rear end 67 of the castle nut 40 comprises a second plurality of apertures 43. According to some embodiments presently disclosed, the first plurality of apertures 47 is positioned directly across from the second plurality of apertures 43. According to some embodiments presently disclosed, one or more apertures 47 are positioned directly across from one or more apertures 43. According to some embodiments presently disclosed, the first plurality of apertures 47 is not positioned directly across from the second plurality of apertures 43. According to some embodiments presently disclosed, one or more apertures 47 are not positioned directly across from one or more apertures 43.

Referring to FIGS. 3a-d, a staking fixture 50 is shown according to some embodiments presently disclosed. The staking fixture 50 comprises a front surface 51 and a rear surface 53.

The staking fixture 50 further comprises an opening 55 configured to accommodate at least a portion of the circumference of the castle nut 40. According to some embodiments presently disclosed, the opening 55 is semicircular. According to some embodiments presently disclosed, the staking fixture 50 defines the opening 55. According to some embodiments presently disclosed, the staking fixture 50 forms the opening 55.

According to some embodiments presently disclosed, the staking fixture 50 comprises one or more protrusions 60 extending into the opening 55 (shown in FIGS. 3a, 3c and 3d).
