Description

FIELD OF THE INVENTION

The present invention relates to handguards for firearms.

BACKGROUND AND SUMMARY

This patent solves the purpose of creating a handguard for firearms that features the capability to be pump action via the “handguard pump” or use the “handguard pump” to charge your standard semi auto rifle that utilized a gas block/tube system.

This handguard is also extremely lightweight and features a never-before-seen prism like design that uses multiple rods forming in a circle to create not only one of the lightest handguards ever produced but it is the most customizable handguard as you can slide attachment mounting points in any increment in either forward or backward direction rather than being forced to use specific holes.

This patent serves the purpose of creating a handguard for firearms that features the capability to be pump action via the “handguard pump” or use the “handguard pump” to charge your standard semi auto rifle that utilizes a gas block/tube system as an optional alternative to the standard rear charge handle.

This handguard solves the problem of not being able to convert a pump action back into a semi-auto so easily, we accomplish this via swapping or blocking the gas system. This can also be solved by swapping barrels and other features that accomplish the same thing.

The above disadvantages are addressed by a firearm assembly comprises a frame defining a bolt passage; a barrel connected to the frame and extending forward of the frame; a bolt operable to reciprocate within the bolt passage between a forward battery position and rearward recoil piston; a forend structure connected to the frame forward to the frame and encompassing a portion of the barrel; a grip slidably connected to the forend structure and connected to the bolt; the grip operable to cycle the bolt between the forward battery position and the rearward recoil piston; and the forend structure including a plurality of parallel rods.

BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

This patent solves the purpose of creating a handguard for firearms that features the capability to be pump action via the “handguard pump” or use the “handguard pump” to charge your standard semi auto rifle that utilized a gas block/tube system. This handguard is also extremely lightweight and features a never-before-seen prism like design that uses multiple rods forming in a circle to create not only one of the lightest handguards ever produced but it is the most customizable handguard as you can slide attachment mounting points in any increment in either forward or backward direction rather than being forced to use specific holes. This creates the most customizable handguard ever made. The “pump action” version of this handguard will be legal in all 50 states and can turn any semi auto standard AR rifle into a pump action by swapping out or blocking off your gas block and tube. The “dual pump” version of this firearm works in conjunction with our dual charge upper and allows you to charge the semi auto firearm via the handguard pump or the rear charge handle rather than just the rear charge handle.

This patent serves the purpose of creating a handguard for firearms that features the capability to be pump action via the “handguard pump” or use the “handguard pump” to charge your standard semi auto rifle that utilizes a gas block/tube system as an optional alternative to the standard rear charge handle. It allows the ability to switch from single pump action to semi-auto pump action via change of the gas system without needing to change the upper or lower by blocking off the gas system. This can also be done by removing the gas system for example changing the barrel. For example a 9 mm direct impingement firearm with no gas tube/gas block. It also keeps the rear charge handle as an optional alternative to charge the firearm which is useful in case of a malfunction on one system. This is possible due to our dual charge upper receiver that was designed for this purpose and to allow the upper to be a side charge if used with a standard (not cage pump) handguard. Our handguard pump tube is a shroud that encases around the entire outside perimeter of the handguard body, this is useful because it provides a larger surface area to grab and is not currently seen in the market. Our handguard pump tube also features slots designed to take attachments via MLOK™ or KEY-MOD™ slots which can allow the handguard tube to have a grip mounted to the bottom for charging it or other accessories installed. Our pump handguard is unique because the charging rod moves the bolt carrier group back when charged without going thru the standard gas tube hole in an upper receiver. Allowing it to be possible to be semi-automatic, this is important because it allows the firearm to be swapped between single pump action and semi auto pump action as well as be fixed as one form. The charging system does not go thru the existing gas tube hole in an upper receiver. Our charging system is a rod that connects to an adapter in the upper receiver that contacts the BCG to move it backwards and charge it. This handguard can be used in any variation of caliber including but not limited to 5.56, .223, .22, .17, 6.5 creedmoor, .308.9 mm, 10 mm, .22LR, 30.06. Including all current Matrix Arms AR9 and 556 designs, models and calibers. A firearm comprising of a handguard that encases and protects around the barrel of the firearm with a manually operated reload mechanism that can function as semi-automatic and or single action by only changing the gas system. Current market handguards cannot accomplish this because they utilize the standard gas tube hole in the upper and standard gas tube location on the bolt carrier group. Our handguard body is one uniform shape comprised of one or multiple pieces to form one solid protective shape. A handguard pump tube that is one solid piece and not comprised of multiple pieces. A handguard pump tube that features a second method of charging, for example keeping the rear charge handle to have a second method of charging in the instance of a malfunction on one system. A handguard with no vertical attachment material in between the horizontal material (horizontal described as left to right when the firearm is being fired from a standard shooting position. Also described as the direction from the muzzle end of the gun to the butt-stock or butt end of the gun. A system that allows you to convert a standard AR15/M16 milspec type rifle or pistol into a pump action or semi auto pump by only modifying with do it yourself at home modifications to the BCG and upper, and adding a handguard. Works with existing market BCG's including the Matrix Arms enhanced BCG that has existed for over one year which are generally a standard milspec BCG featuring only a small side cut modification.

This handguard pump tube encases around over 50% of the outside perimeter of the handguard to give much larger surface area to hold and making the firearm easier to load/charge.

This handguard is extremely lightweight and features a never before seen unique cage type design that uses multiple rods or other shaped bodies for instance square shaped rods as an alternative to cylindrical or octagonal shaped rods forming in a circle to create not only one of the lightest handguards ever produced but it is the most customizable handguard as you can slide attachment mounting points in any increment in either forward or backward direction rather than being forced to use specific holes. This creates the most customizable handguard ever made.

The “pump action” version of this handguard will be legal in all 50 states and can turn any semi auto standard AR rifle into a pump action by swapping out or blocking off your gas block and tube. The “dual pump” version of this firearm works in conjunction with or without our dual charge upper and allows you to charge the semi auto firearm via the handguard pump as an alternative to the rear charge handle. This method of charging allows for much faster follow up shots as your hand does not have to leave the handguard. The semi-automatic model being possible is important for allowing faster follow up shots.

This handguard solves the purpose of allowing it to be charged via a standard rear charging handle or our new handguard pump.

Our charging system does not contact the BCG thru the existing gas tube hole in the front of a standard AR15 upper.

Our pump charging system is located on the outside of the handguard and charges the BCG back by attaching to an adapter on the side of the upper receiver that contacts the BCG.

This handguard and pump charge system solves the problem of not being able to convert a semi-auto AR15 into a dual charge single pump action. By only changing the gas system by removing it or replacing it you can convert a semi-auto AR15 into single pump action.

This handguard solves the problem of not being able to convert a pump action back into a semi-auto so easily, we accomplish this via swapping or blocking the gas system. This can also be solved by swapping barrels and other features that accomplish the same thing.

This handguard solves the problem of not being able to slide attachment pieces side to side beyond a standard MLOK type attachment slot. Allowing for more adjustability and easier adjustability.

This handguard solves the problem of having a handguard pump tube that shrouds over the entire outside of the handguard for better protection and larger surface area.

This handguard pump tube (pump mechanism that your had touches when charging) solves the problem of not being able to mount attachments to the actual pump for example an MLOK slot on the tube itself that allows for attachment of a foregrip on the bottom of the pump tube.

This handguard solves the problem of weight, our 7″ base cage aluminum handguard is lighter than our current 7″ carbon fiber handguard. This is possible because we have the least amount of surface area in our main handguard body (plastic side covers are not the main forming body just additional and optional protective pieces) than any current market handguards.

This handguard solves the problem of not being able to charge your firearm so quickly due to your hand not having to leave the handguard and the surface area of the pump being larger by covering more than half of the outside perimeter of the handguard.

This handguard solves the problem of people not being strong enough to charge a firearm. For example our handguard pump is much easier and requires less force than a standard AR15 or rear charge handle to charge the firearm due to leverage.

This handguard solves the problem of no current pump-action and semi auto-pump action firearm working with an existing standard AR15/M16 BCG with only one modification being required that can be performed at home. Our modification is a small cut into the side of any standard AR15/M16 BCG.

This handguard solves the problem of not being able to have such fast follow up shots after reloading due to less movement needed to recharge your firearm.

This handguard solves the problem of price due to the rods having extremely minimal machining processes done to them. We do not have to machine the body of the housing as all shapes of rods are available throughout the market. Because of this availability and minimal machining we are able to have extremely low costs for such a complex design and compared to other handguards on the market.

This handguard solves the problem of reliability because there is two systems used to charge the firearm. If one system fails such as the charging handle latch breaks you can use the pump. If the pump tube malfunctions you still have a backup rear charge handle.

This handguard solves the problem of customizability because rather than using existing holes featured on current industry handguards including all Matrix Arms current previous designs. Our adapter pieces can be slide forward or backward in any increment to be moved and adjusted.

This handguard and dual charge upper receiver system can be used in conjunction with any standard AR15 type or similar complete lower receiver being capable of converting a semi-auto firearm to a pump action while still keeping the same serial numbered lower receiver.

This invention solves the problem of not being able to convert a standard AR15/M16/A1/A2/MILSPEC type upper receiver into a dual charge via a handle on the side of the upper that allows for side charge and a standard rear charging handle

This invention solves the problem of not being able to convert a standard AR15/M16/A1/A2/MILSPEC type upper receiver into a dual pump action (semi-auto and single action) via a bracket on the side of the upper that allows for an adapter that connects to a charging mechanism on the handguard to allow the BCG to be charged via a mechanism on the handguard for example our pump tube and rod combination.
