Patent Application
20250109925
Firearms are widely used, and among the most common firearms are the AR-15 and AR-10 semi-automatic firearm. Such firearms are comprised of several different components, which generally include a lower receiver, an upper receiver, a stock and a barrel. Although several components are included in the firearm, it is typically only the lower receiver that is technically classified as a firearm and the subject of regulation. In this regard, while most components of a firearm may be readily acquired, the regulations governing firearms tend to make it much more difficult to acquire a lower receiver.
With the proper governmental license, these semi-automatic machineguns may be converted to automatic machineguns by drilling holes into the lower receiver at a specific location on the lower receiver. Currently, there are methods to drill these holes, but the person doing the drilling must line up multiple items to ensure accuracy, and in light of this errors are made.
There is therefore a need in the art for a device, and method of using the same, which allow for the person doing the drilling to properly align these holes while removing the risk of errors being made.
It is believed that no one prior to the inventor has made or used the invention described in the appended claims.
The disclosed aspects will hereinafter be described in conjunction with the appended drawings, provided to illustrate and not to limit the disclosed aspects, wherein like designations denote like elements.
The following description of certain examples of the technology should not be used to limit its scope. Other examples, features, aspects, embodiments, and advantages of the technology will become apparent to those skilled in the art from the following description, which is by way of illustration, one of the best modes contemplated for carrying out the technology. As will be realized, the technology described herein is capable of other different and obvious aspects, all without departing from the technology. Accordingly, the drawings and descriptions should be regarded as illustrative in nature and not restrictive.
It is further understood that any one or more of the teachings, expressions, embodiments, examples, etc. described herein may be combined with any one or more of the other teachings, expressions, embodiments, examples, etc. that are described herein. The following-described teachings, expressions, embodiments, examples, etc. should therefore not be viewed in isolation relative to each other. Various suitable ways in which the teachings herein may be combined will be readily apparent to those of ordinary skill in the art in view of the teachings herein. Such modifications and variations are intended to be included within the scope of the claims.
For clarity of disclosure, the terms “proximal” and “distal” are defined herein relative to an operator grasping a firearm. The term “proximal” refers the position of an element closer to the operator and the term “distal” refers to the position of an element further away from the operator.
Various embodiments will be described below in conjunction with the drawings for purposes of illustration. It should be appreciated that many other implementations of the disclosed concepts are possible, and various advantages can be achieved with the disclosed implementations. Headings are included herein for reference and to aid in locating various sections. These headings are not intended to limit the scope of the concepts described with respect thereto. Such concepts may have applicability throughout the entire specification.
In yet another version, jig (10) could be made from a less durable material, such as aluminum. In such a version, in order to ensure integrity of alignment bore holes (18a) and (18b), stainless steel press bushing fittings should be placed in alignment bore holes (18a) and (18b) prior to use.
In one or more versions, alignment bore holes (18a) and (18b) are between 0.190 and 0.210 inches from outer edge (20a) and (20b), respectively, of jig (10), in other versions, from between 0.194 and 0.206 inches, and in yet other versions from between 0.198 and 0.202 inches. In one version, alignment bore hole (18a) and (18b) are 0.200 inches from outer edge (20a) and (20b), respectively. In one version, alignment bore hole (18a) and (18b) are 0.194 inches from outer edge (20a) and (20b), respectively.
In one or more versions, alignment bore holes (18a) and (18b) are between 0.760 and 0.770 inches from bottom edge (22) of jig (10), in other versions, from between 0.762 and 0.768 inches, and in yet other versions, from between 0.764 and 0.766 inches. In one version, alignment bore holes (18a) and (18b) are 0.765 inches from bottom edge (22). In one version, alignment bore holes (18a) and (18b) are 0.762 inches from bottom edge (22).
In one or more versions, takedown bore plug (16) has a diameter between 0.260 and 0.270 inches, in other versions from between 0.262 and 0.268 inches, and in yet other versions from between 0.264 and 0.266 inches. In one version, takedown bore plug (16) has a diameter of 0.263 inches. In one version, takedown bore plug (16) has a diameter of 0.264 inches.
In one or more versions, jig (10) can be used to convert a semi-automatic AR-15 style firearm, to an automatic AR-15 style firearm. According to the National Firearms Act (NFA), an AR-15 style firearm is considered to be a rifle if configured to be semi-automatic, and a machinegun if configured to be automatic. “Semi-automatic” means that each pull of the trigger releases one round and “automatic” means that the user can pull the trigger one time, and rounds will continue to be released until the user releases the trigger. Firearms within the definition of machinegun include firearms that shoot, are designed to shoot, or can be readily restored to shoot, automatically more than one shot without manual reloading by a single function of the trigger. Of all the different firearms defined as NFA weapons, machineguns are the only type where the receiver of the weapon by itself is an NFA firearm. As a result, it is important that the receiver of a machinegun be properly identified. Many machineguns incorporate a “split” or “hinged” receiver design so the main portion of the weapon can be easily separated into upper and lower sections. Additionally, some machineguns utilize a construction method where the receiver is composed of a number of subassemblies that are riveted together to form the complete receiver.

Additionally, some machineguns utilize a construction method where the receiver is composed of a number of subassemblies that are riveted together to form the complete receiver.
As should be evident by the above discussion, jig (10) provides a unique solution because it includes the pair of alignment bore holes (18a) and (18b). Regardless of what side (102a or 102b) of lower receiver (100) the licensed technician is drilling into, jig (10) will make sure that the drilled holes are in the correct position because of the pair of alignment bore holes (18a) and (18b). On one side of lower receiver (100), one bore hole, either (18a) or (18b) may be utilized, then, when the licensed technician goes to drill on the other side of lower receiver (100), the other bore hole, (18b) or (18a), may be utilized. As discussed above, once bore holes (18a) and (18b) are utilized on both sides of lower receiver (100), the AR-15 will now be considered to be an automatic style firearm.
Although
As discussed above, if jig (10) is made from a less durable material, such as aluminum, placing stainless steel press bushing fittings within bore holes (18a) and (18b) will allow bore holes (18a) and (18b) to withstand the action of a drill being utilized within said bore holes (18a) and (18b). In practice, to allow for the fitting of the press bushing fitting within bore holes (18a) and (18b), while machining jig (10), the diameters of bore holes (18a) and (18b) should be made larger than if jig (10) was being made from stainless steel.
