Abstract
A firearm comprises a frame defining a bolt passage, with a reciprocating bolt received in the passage. The frame defines a magazine well, and a top cover having a forward end pivotally connected to the frame and defining an upper portion of the bolt passage.
Description
- This application claims the benefit of U.S. Provisional Patent Application No. 63/007,183, filed on Apr. 8, 2020, entitled “M20 Autoloader”, which is hereby incorporated by reference in its entirety for all that is taught and disclosed therein.
- The present invention relates to autoloaders for pistols or carbines.
- Autoloaders may suffer from overcomplicated designs that require specialty equipment to manufacture.
- The preferred embodiment addresses these concerns by providing a firearm that comprises a frame defining a bolt passage, with a reciprocating bolt received in the passage. The frame defines a magazine well, and a top cover having a forward end pivotally connected to the frame and defining an upper portion of the bolt passage.

FIG. 15 shows rear angled side view of one configuration. -
FIG. 16 shows side view of one configuration. -
FIG. 17 shows side view of one configuration. -
FIG. 18 shows side view of one configuration. - Lid: The top of the receiver opens up like a machine gun/with pivoting lid and quick release button. In the Lid are Machined on Iron Sights.
- Lock: Fire pin Lock, if receiver lid is open the fire pin lock engages the firing pin and blocks/stops it from being able to go forward and fire a round if the lid is open and trigger is pulled.
- Extractor: Extractor is as big as cartridge and the cartridges slide underneath it as they are being loaded referred to as controlled feed—the bolt always has possession of the cartridge throughout the cycle of the process of feeding, firing and ejection.
- Second Extractor: Opposite side of big extractor is a machined in extractor ledge that serves as a second extractor, in other words the bolt has 2 extractors.
- Ejector: Fixed ejector that also serves as magazine stop, keeps magazine from being pushed in too far.
- Charge Handle: Left side cocking or clearing of the M20, handle does not move whilst firing it is stationary. Considered mil spec.
- Quick Change Barrel: Barrel changes out quickly with large front barrel retaining nut, it's 2-inch diameter is easy to hold onto whilst firing and is a very unique look I have used on over 3500 rifle builds.
- Looks: The design is very unique in looks, very square and heavy duty using a square bolt and unique flip up top cover and big barrel retaining nut.
- Multi Use: The M20 is sold as a pistol or a carbine because of quick change barrels and the easily installed rear folding stock adapter.
- Magazines: Built to take Glock magazines which are available in 10-100 round capacity.
- Caliber: Originally designed to shoot 9 mm; however, it is easily adaptable to take several pistol/carbine calibers including but not limited to 40 SW thru 45 ACP.
- Recoil Spring: Uses a SKS recoil spring mounted in square bolt. The M20 does not need a recoil tube to function, spring is retained in bolt and upper receiver. Makes for a very small footprint for a pistol configuration.
- The following is a further breakdown of the above-referenced individual parts of the new M20.
- No. 1: Lid/Top Cover. A lid (top cover) pivots open to the front like a machine gun. The lid has a quick detach latch that snaps over the latch on a receiver. There is a heat-treated steel plate in the lid for wear of fire pin lock pins that are spring loaded.
- No. 2 Lock Fire Pin Lock. Lock: Fire pin lock, if receiver lid is open the fire pin lock engages the firing pin and blocks/Stops it from being able to go forward and fire a round if the lid is open and trigger is pulled.
- No. 3 Extractor/Controlled Feed. Controlled feed extractor is as big as cartridge/the cartridges slide underneath it as they are being loaded referred to as controlled feed—the bolt always has possession of the cartridge throughout the cycle of the process of feeding, firing and ejection. Only a few bolt action rifles use or have used this feature. M20 is a semi-automatic.
- Most weapons like M20 use a push feed to push the cartridge from the magazine and then the extractor snaps over the lip of the cart. Most weapons in these calibers only use a 0.125 wide extractor.
- No. 4 Secondary extractor/Makes a twin extractor system
- Second extractor: Opposite side of big extractor is a machined in extractor ledge that serves as a second extractor, in other words the bolt has 2 extractors
- Secondary extractor—opposite large controlled feed extractor.
- A very small 0.060×0.015 slot opposite controlled feed extractor.
- As the cartridge feeds into the chamber area, it is forced to snap underneath from the spring-loaded controlled feed extractor.
- Once the cartridge is in both extractors, ifs like one piece. Very stuck and takes quite a bit of force to eject it.
- No. 5 Fixed ejector. Fixed ejector that also serves as magazine stop, keeps magazine from being pushed in too far. A slot in the bolt allows bolt to slide past ejector.
- No. 6 Charge handle. Left side cocking or clearing of the M20, handle does not move whilst firing it is stationary. Considered mil spec.
- This feature is found on many military type rifles.
- Even an AR 15 uses a charging handle that does not move while firing.
- On the M20 it is put together in 3 pieces with a ball detent lock to keep handle forward and stationary whilst firing.
- No. 7 Quick change barrel. Barrel changes out quickly with large front barrel retaining nut, it's 2-inch diameter is easy to hold onto whilst firing and is a very unique look I have used on over 3500 rifle builds. For convenience as well as military application when a barrel is burnt up from rapid automatic fire
- No. 8 Appearance. The design has a unique visual appeal. With a military and industrial feel using a very square look and heavy-duty design consisting of: a square receiver, a square bolt, unique flip up top machine gun cover, big barrel retaining nut and one-piece sight machined in. The M20 needs no tools to pull bolt out for cleaning. The flip up lid is machined with a one-piece conventional sight.
- No. 9 Multi Use. The M20 is sold as a pistol or a carbine because of quick change barrels and the easily installed rear folding stock adapter.
- No. 10 Magazines. Built to take Glock magazines which are available in 10-100 round capacity.
- Caliber. Originally designed to shoot 9 mm; however, it is easily adaptable to take several pistol/carbine calibers including but not limited to 40 SW thru 45 ACP.
- We used Glock magazines because of the wide variety caliber and capacity available.
- No. 11 Recoil Spring. Uses a SKS recoil spring mounted in square bolt. The M20 does not need a recoil tube to function, spring is retained in bolt and upper receiver. Makes for a very small footprint for a pistol configuration. A unique and simple solution for a self-contained bolt and spring. Readily available SKS spring. Eliminated need for a buffer tube/rear stock.
- The M20 was designed around the AR15/M16 trigger/safety system.
- The design is so simple, well thought out and easy to manufacture, there's a potential for small gun machine shops that will want to copy the M20. Hence the reason for this patent.
- The M20 can be made fast and cheap, and the price point is correct to make lots of sales and profit.
