Take-down compact precision rifle

Abstract

A take-down rifle including modular components. A first and a second rifle section comprising first and second receiver portions, respectively, allow the rifle to be quickly assembled and disassembled. The first rifle section also includes a rifle barrel. Mounting points on the first rifle section allow a coupled optical sight to remain fixed in relation to the barrel after assembly or disassembly so that the optical sight remains zeroed.

7. The method of claim 6, further comprising: providing a second takedown coupling section between a buttstock and the second section, wherein the second takedown coupling section couples with the second section on an end of the second section which opposes the first section and the buttstock, wherein the second section further comprises a grip section; and coupling the buttstock with the second section at the second takedown section coupling section.

8. The method of claim 6, further comprising: providing a sighting system and coupling the sighting system with said plurality of mounting points.

9. The method of claim 6, further comprising providing: a bolt that is slideably inserted into the first and second receiver portions; and coupling the bolt into the second receiver portion.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The detailed description of the drawings particularly refers to the accompanying figures in which:

(2) FIG. 1 shows an exemplary take-down compact precision rifle in its assembled configuration;

(3) FIG. 2 shows an exemplary take-down compact precision rifle disassembled for transportation;

DETAILED DESCRIPTION OF THE DRAWINGS

(6) Embodiments of the invention described herein are not intended to be exhaustive or to limit the invention to precise forms disclosed. Rather, the embodiments selected for description have been chosen to enable one skilled in the art to practice the invention.

(7) Referring initially to FIG. 1, an embodiment of the invention comprises components of the U.S. Military's proven MK 13 precision rifle platform. An exemplary primary take-down point 201 can be manufactured to divide rifle into a first rifle portion 99 and a second rifle portion 98. A receiver 103 is divided at the primary take-down point 201 into a first receiver section 401 and a second receiver section 402. The first receiver section 401 is coupled to a barrel 100 that is included in the first rifle portion 99. The second receiver section 402 is part of the second rifle portion 98. A chamber 101 is either coupled with or formed into the rifled barrel 100. In other words, in at least one possible embodiment, the exemplary chamber 101 is milled or forged inside the barrel 100. The end of the barrel 100 that is formed with the chamber 101 is coupled with (e.g., screwed into) the first receiver section 401. The receiver 103 receives and guides a bolt 104 as the bolt 104 removes a live round (not shown) from a magazine 108 and locks the live round into the chamber 101. The bolt 104 includes a firing pin (not shown) and positions the firing pin so that an activation of a trigger 107 will release the pin causing it to contact with the round's primer. A sighting or optics system (not shown) is mounted to an exterior surface of a section of the rifle that houses or encloses the chamber 101 at mounting points 102. A buttstock 105 may be used to brace the rifle platform against an operator's shoulder. A grip 106 provides support for the operator's trigger hand. A bi-pod 109 can be coupled on one end to a forward portion of the platform.

(8) FIG. 2 shows the platform of FIG. 1 disassembled for transportation. The exemplary primary take-down point 201 is shown dividing the receiver 103 see FIG. 1) into the first receiver section 401 and the second receiver section 402 see FIG. 1). The barrel 100 couples (e.g., screws into) with the first receiver section 401 see FIG. 1). Alignment pins 203 can be embedded within the first rifle portion 99 such that alignment pins 203 can enter recesses 251 to ensure proper alignment of the first rifle portion 99 with the second rifle portion 98 during reassembly. The first and second rifle portions 99, 98 may be reassembled by inserting a locking pin 301 (see FIG. 1) through a pair of locking tabs 204, 204 formed on the second rifle portion 98 and through a corresponding hole 205 formed in the first rifle portion 99 that is perpendicular to an axis passing through a center of the barrel 100 (see FIG. 1). The sighting or optics system (not shown) is fixed with respect to the first rifle portion of the takedown rifle in order avoid a need to readjust the sighting alignment based on disassembly of the rifle. A second take-down section 202 can be manufactured on an end of the second rifle portion 98 opposing the first rifle portion 99 to allow a third rifle portion 97 (including, e.g., the buttstock 105 see FIG. 1)) to be detached from the second rifle portion 98 which includes grip 106 see FIG. 1).

(9) FIG. 3 shows a close-up view of exemplary primary take-down point 201 in its assembled configuration. The first rifle portion 99 (see FIG. 2) and the second rifle portion 98 (see FIG. 2) of the platform are locked into an exemplary assembled configuration through the use of locking pin 301. Other design approaches can be used to couple or lock the first and second rifle portions 99, 98 (see FIG. 2). A sighting or optics system 503 can be coupled to mounting points 102.

(10) FIG. 4 shows a cross-section view of an exemplary bolt-action receiver 103. In this exemplary disclosure, as discussed above, the receiver 103 is divided at primary take-down point 201 into the second receiver section 402 and the first receiver section 401. The first receiver section 401 is formed to accept a forward end of the bolt 104 (See FIG. 1) and capture locking lugs into locking lug cavities 403 formed thereon with corresponding locking surfaces 404. Axis 501 extends through the center of barrel 100.
