The present invention relates to firearm manufacture. More particularly, the present invention relates to a firearm receiver and a method of manufacturing it.
Firearm receiver is a part of a firearm that provides housing for a hammer, a bolt and/or a firing mechanism. Unfinished receivers, also referred to as 80% receivers, are only about 80% completed. It is up to a customer to finish manufacturing a firearm by performing the remaining 20% of the drilling and/or milling. Due to complexities involved, many customers do not have the equipment and/or knowledge to properly manufacture the last 20% of the firearm receiver.
Therefore, there is a need for a firearm receiver and a method of manufacturing it such that a customer can easily finish manufacturing the last 20% of the firearm.
In the following description, like reference numbers are used to identify like elements. Furthermore, the drawings are intended to illustrate major features of exemplary embodiments in a diagrammatic manner. The drawings are not intended to depict every feature of every implementation nor relative dimensions of the depicted elements, and are not drawn to scale.
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
According to some embodiments, the first panel 15 and the second panel 20 comprise through-holes 45 and 50 configured to align with a respective through-holes of an upper receiver (not shown) whereby a pin is inserted into and passes within each through-hole 45, 50 to secure the assembled receiver 10 with the upper receiver (not shown). According to some embodiments, the first panel 15 and the second panel 20 comprise safety-selector through-holes 55 whereby a pin is inserted into and passes within the safety-selector through-holes 55 to secure a safety selector mechanism inside the assembled receiver 10. According to some embodiments, the first panel 15 and the second panel 20 comprise trigger through-holes 60 whereby a pin is inserted into and passes within the trigger through-holes 60 to secure a trigger mechanism inside the assembled receiver 10. According to some embodiments, the first panel 15 and the second panel 20 comprise hammer through-holes 65 whereby a pin is inserted into and passes within the hammer through-holes 65 to secure a hammer mechanism inside the assembled receiver 10.
Referring to
According to some embodiments, the upwardly extending lobe 80 is used to mount a buttstock (not shown) to the assembled receiver 10 and is used to align a receiver extension (not shown) with a bolt carrier housed within an upper receiver (not shown). The receiver extension (not shown) generally houses an action (or recoil) spring and a buffer assembly (not shown). Upon discharge of a round, the bolt carrier within the upper housing is driven rearward by action of the gas discharged by the firing action. The buffer assembly and 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. According to some embodiments, the upwardly extending lobe 80 comprises a generally circular threaded through-hole 85 adapted to receive the mating male threads on the receiver extension (not shown).
According to some embodiments, at least portion of the support member 81 is sandwiched between the first panel 15 and the second panel 20 to form the assembled receiver 10 as shown in
According to some embodiments, the first panel 15 and the second panel 20 comprise one or more through openings 100 configured to accommodate one or more fasteners 105. The fasteners 105 may be screws, pins, socket head cap screws. The fasteners 105 are configured to couple the first panel 15 with the second panel 20.
According to some embodiments, the support member 81 comprises a through opening 101 configured to accommodate one of the fasteners 105. One of the fasteners 105 is configured to couple the support member 81 with the first panel 15 and the second panel 20 though the opening 101.
According to some embodiments, the first panel 15 comprises a generally flat top surface 110 (shown in
According to some embodiments presently disclosed, the first panel 15 and/or the second panel 20 comprise a first material having a first melting point and the buffer tube insert 30 comprises a second material having a second melting point.
According to some embodiments, the assembled receiver 10 may comprise a fastener 120 configured to couple the first panel 15 with the second panel 20 through the through-holes 45. The fastener 120 may also couple the assembled receiver 10 with an upper receiver (not shown).
According to some embodiments presently disclosed, the first material is steel, aluminum, metal, polymer, and/or sintered metal powder. According to some embodiments presently disclosed, the second material is steel, aluminum, metal, polymer, and/or sintered metal powder. According to some embodiments presently disclosed, the first melting point is lower than the second melting point.
According to some embodiments presently disclosed, the one or more through openings 100 are generally circular threaded through-holes adapted to receive the mating male threads on the one or more fasteners 105.
While several illustrative embodiments of the invention have been shown and described, numerous variations and alternative embodiments will occur to those skilled in the art. Such variations and alternative embodiments are contemplated, and can be made without departing from the scope of the invention as defined in the appended claims.
As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the content clearly dictates otherwise. The term “plurality” includes two or more referents unless the content clearly dictates otherwise. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the disclosure pertains.
