DETAILED DESCRIPTION

The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.

Referring to FIG. 1, a firearm is shown. While the drawings show an AR-15 type platform, it is understood that any firearm with a detachable magazine (1-1), a magazine release button (1-2) and a magazine catch (2-1), can be used. It is understood that platforms may differ in certain respects and name of parts, however the methods and parts used are easily adaptable to these platforms. As with most rifles, a magazine (1-1) is retained in the lower receiver (1-3) by a magazine catch (2-1). Multiple rounds of ammunition can be secured in, and fed by, the magazine (1-1) into the firing chamber of the weapon. Once the magazine (1-1) is empty, a user will typically depress the magazine release button (1-2) which will in turn actuate the magazine catch (2-1). Actuation of the magazine catch (2-1) will push the magazine catch (2-1) away from the lower receiver (1-3) and will disengage the magazine (1-1) allowing it to be removed from the lower receiver (1-3). The magazine (1-1) can either be replaced with another magazine (1-1) or the reloaded magazine (1-1). This mechanism allows for quick reloading of the firearm (FIG. 1).

Referring to FIG. 2, a close up view of the magazine release area of an AR15 type platform is shown.

Referring to FIGS. 3, 4, and 5, the magazine catch (3-1), the spacer (3-2), and the internally threaded bolt (3-3), hereafter referred to as the Spartan Lock are shown. In use, the user will remove the stock magazine release button (1-2) and replace it with the spacer (3-2) and secure the spacer (3-2) with the Spartan Lock (3-3) to the magazine catch (2-1). Ensure a magazine (1-1) is inserted in the lower receiver (1-3) prior to fully tightening the Spartan Lock (3-3). The Spartan Lock (3-3) is comprised of a one-way head (5-2), and an internally threaded section (5-3). The one-way head (5-2) is designed such that a screwdriver can engage the one-way head (5-2) when rotating it in the tightening direction. When trying to rotate the Spartan Lock (3-3) in the loosening direction, the screwdriver will slide up the sloped surface of the one-way head (5-2) and be unable to establish rotation. Thus, once the Spartan Lock (3-3) is fully tightened onto the magazine catch (2-1) the user will not be able to remove the magazine (1-1) from the lower receiver (1-3). This will permanently secure the magazine (1-1) in the receiver (1-3). In some embodiments, the one-way head (5-2), has two engagement surfaces (5-2-1), and two sloped surfaces (5-2-2). When the screwdriver rotates in the tightening direction, the screw driver hits the engagement surfaces (5-2-1), and rotates the Spartan Lock (3-3). When the screw driver is rotated in the opposite direction, it slides up the sloped surfaces (5-2-2) and off the one-way head (5-2) of the Spartan Lock (3-3). Thus, one is only able to insert the Spartan Lock (3-3) with a screw driver. If one wanted to remove the Spartan Lock (3-3), a means other than simple hand tools would need to be employed.

As shown in FIG. 6, a cross section of the magazine catch area (FIG. 3), showing the relationship if the Spartan Lock (3-3), the spacer (3-1), and the magazine catch (2-1), when installed in an AR-15 type platform (FIG. 1). In FIG. 6, the spacer (3-1), is inserted into the right side of the lower receiver (1-3), the magazine catch (2-1) is inserted into the left side of the lower receiver (1-3), and the Spartan Lock (3-3) is inserted into the open end of the spacer (3-1). Using a screwdriver to bite onto the engagement surfaces (5-2-1) of the Spartan Lock (3-3), rotate the Spartan Lock (3-3) in the tightening direction to engage the Spartan Locks' (3-3) internally threaded portion (5-3) with the external threads of the magazine catch (2-1). After initially engaging the Spartan Locks' (3-3) internally threaded portion (5-3) with the external threads of the magazine catch (2-1), insert a magazine (1-1) into the lower receiver (1-3), ensuring the magazine catch (2-1) engages the magazine (1-1). Slight finger pressure on the magazine catch (2-1) will assist in ensuring the magazine (1-1) is properly seated. Complete the tightening of the Spartan Lock (3-3) until the Spartan Lock (3-3) is hand tight, and the head (5-2) is below flush with the spacer (3-1).

As seen in FIG. 7, to load the AR-15 type platform, (FIG. 1) the user would have to at least partially takedown the AR-15 type platform, (FIG. 1), and load the ammunition into the magazine (1-1). This will greatly increase the amount of time that one would need to reload the Ar-15 type platform, (FIG. 1). By installing the Spartan Lock (3-3), it will convert the Ar-15 type platform, (FIG. 1) to a permanently fixed magazine Ar-15 type platform (FIG. 1).

A method for permanently affixing a magazine (1-1) to an Ar-15 type platform (FIG. 1), comprises one or more of the following steps:

Step 1 verify that the Ar-15 type platform (FIG. 1), is unloaded and in a safe condition;

Step 2 remove the magazine release button (1-2), or in the case that a temporary magazine locking device is installed, remove that from the Ar-15 type platform (FIG. 1), according to the manufacturer directions;

Step 3 insert the spacer (3-1) into the lower receiver (1-3) from the right side of the AR- 15 type platform (FIG. 1);

Step 4 insert the magazine catch (2-1) into the lower receiver (1-3) from the left side of the Ar-15 type platform (FIG. 1);

Step 5 insert the Spartan Lock (3-3) into the open end of the spacer (3-1);

Step 6 Using a screwdriver to bite onto the engagement surfaces (5-2-1) of the Spartan Lock (3-3), rotate the Spartan Lock (3-3) in the tightening direction to engage the Spartan Locks' (3-3) internally threaded portion (5-3) with the external threads of the magazine catch (2-1);

Step 7 After initially engaging the Spartan Locks' (3-3) internally threaded portion (5-3) with the external threads of the magazine catch (2-1), insert a magazine (1-1) into the lower receiver (1-3), ensuring the magazine catch (2-1) engages the magazine (1-1). Slight finger pressure on the magazine catch (2-1) will assist in ensuring the magazine (1-1) is properly seated;

Step 8 Complete the tightening of the Spartan Lock (3-3), until the Spartan Lock (3-3) is hand tight, and the head (5-2) is below flush with the spacer (3-1).

As seen in FIG. 7, to load the Ar-15 type platform, (FIG. 1) the user would have to at least partially takedown the Ar-15 type platform, (FIG. 1).

A method for loading a permanently affixed magazine (1-1) in an Ar-15 type platform, (FIG. 1) having a permanently affixed magazine (1-1), comprises one or more of the following steps:

Step 1 verify that the Ar-15 type platform (FIG. 1), is unloaded and in a safe condition;

Step 2 push from the left side of the Ar-15 type platform, (FIG. 1), and/or, pull from the right side, the takedown pin (1-5) to unlock the upper receiver (1-4) from the lower receiver (1-3);

Step 3 allow the upper receiver (1-4) to rotate forward, exposing the lower receiver (1-3), and the magazine (1-1) permanently affixed therein;

Step 4 load ammunition in the magazine (1-1) by placing a single round on the magazine feed lips (7-1), and pressing down on that round until it is captured by the magazine (1-1), repeating until desired amount of rounds have been loaded into the magazine (1-1); and

Step 5 return the upper receiver (1-4) to a closed position and secure the upper receiver (1-4) to the lower receiver (1-3) by reinserting the takedown pin (1-5).

A reference letter to new DOJ legislation is provided in the following paragraph.

We have developed the “Spartan Lock” to make available to all users and holders of the weapons identified by the California Department of Justice (DOJ) NEW FIREARMS LEGISLATION, Senate Bill 880/Assembly Bill 1135-Firearms: Assault Weapons, completely compliant with this legislation. (See copy of legislation in its entirety later). The essence of the DOJ legislation's newest version of the law will revise the definition of an “assault weapon” to mean the following: “A semiautomatic, centerfire rifle, pistol, or shotgun that does not have a fixed magazine but has any one of the following and other specifically denoted appurtenances that enhance such weapons:

• (A) A pistol grip that protrudes conspicuously beneath the action of the weapon.
• (B) A thumbhole stock.
• (C)A folding or telescoping stock.
• (D) A grenade launcher or flare launcher.
• (E) A flash suppressor.
• (F) A forward pistol grip.
  A “fixed magazine” will be defined to mean an ammunition feeding device, contained in, or permanently attached to, a firearm in such manner that the device cannot be removed without disassembly of the firearm action. To learn more about the firearm laws, refer to the CA Legislation Information page. http://leginfo.legislature.ca.gov/faces/billSearchCIient.xhtml. The DOJ has for years been pondering how to limit the ability of “assault weapons” to be rapidly reloaded. Reloading these weapons by just releasing the magazine and quickly inserting another magazine. Sometimes this firepower has even ‘outgunned’ Law Enforcement (LE) and been contributory to numerous mass shootings and heinous acts by individuals, groups, and terrorists. This new legislation has been drafted specifically to address this issue. Our “Spartan Lock” is a small self, or gun dealer, gunsmith, simply installed device to convert these weapons with NON-FIXED MAGAZINES into compliance with the new California legislation and laws.
  We expect that “Spartan Lock” will also enable users to comply with similar laws in other states as well. The Spartan Lock permanently attaches to a firearm its ammunition feeding device/magazine in such manner that the device cannot be removed without disassembly of the firearm action. The Spartan Lock once affixed is permanent and would require machining to remove the lock or magazine. Thereby forcing these firearms to become as safe as the call for good gun control can apply. In short, this device when installed will make such firearms compliant with the new legislation. As opposition to the new legislation grows the “Spartan Lock” will give users the ability to remove their firearms from the ‘EVIL’ assault weapon category and not find themselves out of compliance with the law and facing potentially severe civil and criminal penalties. The “Spartan Lock” is intended to make compliance with the new legislation viable and less distasteful, thereby helping accomplish the overall goal of public safety and overall good of the populace.

A copy of the text from the “CALIFORNIA DEPARTMENT OF JUSTICE BUREAU OF FIREARMS New Firearms Legislation, Senate Bill 880/Assembly Bill 1135—Firearms: Assault Weapons, Effective Jan. 1, 2017, “Bullet Button” firearms will be considered assault weapons” is provided in the following paragraph.

The newest version of the law will revise the definition of “assault weapon” to mean the following:

• (A) A pistol grip that protrudes conspicuously beneath the action of the weapon.
• (B) A thumbhole stock.
• (C) A folding or telescoping stock.
• (D) A grenade launcher or flare launcher.
• (E) A flash suppressor.
• (F) A forward pistol grip.
• A semiautomatic, centerfire rifle that has a fixed magazine with the capacity to accept more than 10 rounds. A semiautomatic, centerfire rifle that has an overall length of less than 30 inches.

Pistols: A semiautomatic pistol that does not have a fixed magazine but has any one of the following:

• (A) A threaded barrel capable of accepting a flash suppressor forward handgrip, or silencer.
• (B) A second handgrip.
• (C) A shroud that is attached to, or partially or completely encircles, the barrel that allows the bearer to fire the weapon without burning the bearer's hand, except a slide that encloses the barrel.
• (D) The capacity to accept a detachable magazine at some location outside of the pistol grip.
• A semiautomatic pistol with a fixed magazine that has the capacity to accept more than 10 rounds.
