This application claims the benefit of U.S. Provisional Patent Application No. 62/570,331 filed on Oct. 10, 2017, entitled “Swinger Stock and Stubby Sling Mount”, and also claims the benefit of U.S. Provisional Patent Application No. 62/570,339 filed on Oct. 10, 2017, entitled “Swinger Stock”, and also claims the benefit of U.S. Provisional Patent Application No. 62/675,859 filed on May 24, 2018, entitled “Insert for the Sopmod Stock”, which are hereby incorporated by reference in its entirety for all that is taught and disclosed therein.

FIELD OF THE INVENTION

The present invention relates to sling attachments, sopmod stocks and, more particularly, to a rotational insert for the sopmod stock.

BACKGROUND OF THE INVENTION

Currently, all sling attachments are non-movable sling mounts. This style sling mount limits the operator to only one attachment point on his rifle, thus limiting the shooter's ability to switch from their strong side shoulder to their weak side shoulder without sling interference. In addition, it limits the operator's choice of mounting their sling to either the left side of the firearm, the right side of the firearm, or in the lower middle of the receiver, directly under the buffer tube, and directly in line with the shooter's hand.

Also, this style sling mount limits the operator to only one attachment point on their rifle, the left side of the firearm, the right side of the firearm, or in the lower middle of the receiver, thus, limiting the shooter's ability to switch from their strong side shoulder to their weak side shoulder without sling interference.

These mounting locations make it difficult to transition from strong side, to weak side, when shooting from behind a barrier/barricade, when engaging targets while shooting out of a window of an automobile, or when clearing the corners inside of a room.

Moreover, by mounting the sling to the left side of the firearm, the right side of the firearm, or in the lower middle of the receiver, directly under the buffer tube, it places the sling directly in line with the shooter's hand and could possibly interfere with shooters who have large hands or if they are wearing gloves.

All of the AR style collapsible stocks that are currently being sold have built-in sling attachment points that are non-movable and either mount on the left side or the right side of the stock.

Lewis Machine & Tool Company (LMT) and Bravo Company manufacture two similar style stocks. LMT manufactures the SOPMOD/Crane Stock and Bravo Company manufactures a similar design, referred to as the B5 SOPMOD stock. This stock design is used, and preferred, by many Special Forces and SWAT Teams around the world.

The limitations of the prior art are addressed by providing a rifle stock for a firearm. The rifle stock comprises a body with a bore having a forward opening that receives a rifle buffer tube. The body of the rifle stock defines a pocket at a level below the bore. The pocket of the body has a forward opening, and the stock comprises a sling support element. The sling support element has a mating element pivotally received in the pocket.

Tech-10 Tactical found a way to improve on this popular design and make this style stock even better for the operator. Tech-10 Tactical developed an insert for the front of the stock that is guaranteed to give every operator a major tactical advantage over any stock currently on the market today.

This accessory converts the current SOPMOD stock into a stock where you have a full 190 degrees of rotation, with a single point sling, when used in conjunction the Stubby Sling Mount.

This allows the shooter to transition from strong side, to weak side, with no interference from their sling or when shooting from behind a barrier/barricade, engaging targets while shooting out of a car window or when clearing rooms/corners inside a building.

Finally, by mounting the sling directly at the front of the stock and under the buffer tube the shooter's hand never comes in contact with their sling.

The Swinger Stock & Stubby sling mount consists of two individual pieces working in concert to produce a user-friendly design while making it the most secure Quick Detachable (QD) style sling mount on the market today.

The first of the two pieces is the Stubby sling mount. It is made of 304 stainless steel. The sling mount measures 1.75″×1 ½″×⅜″ and has ¼″ holes on the left and right side of the sling mount, at the top and at the bottom; and in the middle, is a ⅝″ hole designed for a QD insert to be installed and held in place using epoxy and ¼″ pins inserted in the left side and the ride side of the Stubby sling mount.

The Stubby sling mount will rotate a full 180 degrees. Thus, allowing the user to easily switch from one shoulder to the opposite shoulder without any interference from the sling.

Also, by placing the sling mount in the middle of the stock, and directly at the front of the stock, it completely eliminates any contact of the sling with the shooters hand while their hand is on the pistol grip.

However, the most significant advantage of this design, mounting the QD insert at the front of the stock, is when the weapon is not shouldered but it is being suspended in air by the sling.

Since the weight of the weapon is exerting a downward force on the sling, this new design capitalizes on this downward force and uses it to push the QD sling mount upward and into the QD insert. This eliminates all stresses on the ball bearings located around the base of the QD.

As an example, the very best QD sling mount on the market today requires about 450 psi of pressure to pull the QD sling mount out of the QD insert. With this newly designed stock and sling mount, it is virtually impossible for the QD sling mount to be pulled out of the QD insert.

The weight of the weapon is pushing the QD sling mount into the QD insert located on the stock. It is not pulling the QD sling mount tangentially or out of the insert, which is how all other QD sling mounts are currently manufactured to remain secured.

This new concept totally eliminates any stresses on the ball bearings, unlike every other QD sling mount on the market.

As an example, the very best QD swivel on the market today requires about 450 psi of pressure to pull the QD mount out of the insert. With this newly designed stock, it is virtually impossible for the QD mount to be pulled out of the QD insert.

The weight of the weapon is pushing the QD insert downward on to the QD swivel. It is not pulling on the QD attachment point, which is how all other QD sling mounts are currently manufactured.

This new concept totally eliminates any stresses on the ball bearings, unlike every other QD sling mount on the market.

The accessory for the LMT and Bravo Company SOPMOD stock utilizes two individual pieces, a custom made insert that mounts into the cavity at the bottom center of the SOPMOD stock, and a 3/16″ tension pin to secure the insert firmly in place so that it will never accidently fall out of the stock.

The accessory is designed to be used with the Stubby Sling mount. After inserting the Stubby Sling mount into the front of the stock it allows a full 190-degrees of rotation with a single point sling while attached to the firearm.

The material of the insert is made of glass filled polymer for its durability.

By using this accessory with the Bravo SOPMOD stock, it allows your sling to be mounted on the front the stock and offers 190 degrees of rotation. With other stocks you have only two options, you can mount your sling on the left or right side of the firearm and offers no rotational advantage. This causes undue sling tension when switching from a strong side to a weak side shooting position.

In addition, when the operator isn't shooting his weapon the firearm is hanging down in front. Tech-10 Tactical saw an additional opportunity and designed the accessory to capitalized on it.

With the weight of the weapon exerting a downward force on the sling, our design capitalizes on this downward force and uses it as an advantage by push the Stubby sling mount upward and into the QD insert. This design eliminates all stresses on the ball bearings located around the base of the QD and essentially eliminates any chance of the attachment point from pulling out of the insert.

Moreover, the very best QD attachment on the market today fails at about 450 psi of pulling force on the insert. With our Stubby sling mount, it is virtually impossible to be pulled out of the QD insert. The weight of the weapon is pushing downward on the Stubby Sling Mount, it is not exerting a pulling force at the attachment point, so it cannot be pulled out.

The present invention can be assembled by following these steps:

Step 1: Place the SOPMOD stock, the insert, the 3/16″ roll pin, a small hammer and the roll pin punch in front of you.

Step 2: Stand the stock up on the butt pad Place the custom made inert into the cavity at the front of the stock.

Step 3: Place the custom made inert into the cavity at the front of the stock. Next, take your hammer and tap the insert into the cavity until it comes to a complete stop. If performed correctly you should be able to see thru the hole without any material being in the way.

Step 4: Insert the 3′16″ roll pin into the hole on the side of the stock.

Step 5: Take the hammer and slightly tap the 3/16″ roll pin until it is flush with the side of the stock.

Step 6: The edge of the roll pin should be even with the stock and the insert.

Step 7: When the insert is complete it should resemble FIG. 10 and FIG. 11.

Step 8: Place the Bravo stock on the buffer tube of your weapon.

Step 9: Insert the Stubby sling mount into the attachment point at the front of the stock.

Now conduct a function check. Pull on the sling while making sure the Stubby Sling Mount remains securely fastened to the SOPMOD stock insert. Once you have verified the sling is securely fastened you are ready to use your firearm.
