The present invention relates generally to firearms. More specifically, the present invention relates to muzzle devices for firearms.
A muzzle device is a device that is typically fixed to the muzzle of the barrel of a firearm in order to modify the functionality and/or operational capabilities of the firearm. Muzzle devices have been designed to reduce recoil, hide flash, adjust choke, act as an offensive weapon, and/or breach doors. Muzzle devices for breaching doors (also known as “breachers,” “breacher tips,” and “door breachers”) are commonly fixed (i.e., welded, soldered, or threaded) to the muzzle of shotgun barrels. They typically include aggressive teeth at the forward end designed to bite into the door and hold the muzzle in position over the door hinges while the shooter presses the muzzle device teeth against the door and pulls the trigger.
However, currently available muzzle devices are designed for use only on firearms with static (i.e., non-reciprocating) barrels. These muzzle devices are not safe to use on firearms with handguards and reciprocating barrels, such as AR-platform firearms with recoil-based operating systems, because the muzzle device can contact the handguard surrounding the barrel when the barrel reciprocates rearward inside the handguard during operation and cycling of the firearm. This can prevent the firearm from cycling, damaging the barrel, handguard, and muzzle device, and it may also injure the shooter or others.
One type of firearm operating system that makes use of a reciprocating barrel is a short recoil operating mechanism. Numerous embodiments of short recoil operating mechanisms are known. In general, upon firing, the barrel and bolt of a short recoil operating mechanism recoil together a short distance before the bolt unlocks from the barrel and they separate. The barrel stops relatively quickly while the bolt continues rearward, extracting a casing from the chamber and compressing the recoil spring. The bolt then moves forward again and feeds a new cartridge (i.e., shell) into the chamber. During the last portion of its forward travel, the bolt locks back into the barrel and pushes the barrel forward back into battery. This type of short recoil operating mechanism is exemplified by the “GEN-12” AR-platform 12-gauge shotgun firearm manufactured by Genesis Arms, LLC and disclosed in U.S. Pat. No. 10,605,553.
Aspects of the present invention provide a muzzle device for firearms with short recoil operating mechanisms and handguards (e.g., AR-platform firearms). The muzzle device does not contact the handguard during cycling of the firearm and does not require the reciprocating barrel to carry the weight of the muzzle device during cycling of the firearm.
In one aspect, a muzzle adapter for a firearm includes a base portion, and an extension portion. The base portion is configured to attach to a handguard of the firearm and extend radially inward toward a longitudinal axis and a barrel of the firearm. The base portion is configured to receive the barrel of the firearm therein. The extension portion is attached to the base portion and supported by the base portion. The extension portion is configured to receive the muzzle attachment in the base portion is closer to about stock of the farm than the extension portion when the muzzle adapters properly attached to the handguard firearm such that the extension portion extends forward from the base portion and the base portion is rearward of the extension portion. The butt stock defines the rear end of the firearm.
In another aspect, a firearm includes a barrel, handguard, and a muzzle adapter. The barrel extends along a longitudinal axis and includes a bore therein. The handguard generally surrounds the barrel along a portion of the barrel. The muzzle adapter includes a base portion and an extension portion. The base portion is configured to attach to the handguard and extend radially inward toward the longitudinal axis and barrel of the firearm from the handguard. The base portion is configured to receive the barrel of the firearm therein. The extension portion is attached to the base portion and supported by the base portion. The extension portion is configured to receive a muzzle attachment and the base portion is closer to about stock of the firearm than the extension portion when the muzzle adapter is properly attached the handguard of the firearm such that the extension portion extends forward from the base portion and the base portion is rearward of the extension portion.

In one embodiment, the muzzle adapter 22 includes a base portion 26 and an extension portion 28. In one embodiment, the base portion 26 is annular or disk shaped and the extension portion 28 is tubular or conical. The base portion 26 is configured to attach to the handguard 17 and extend radially inward from the handguard 17 toward the longitudinal axis 34 and the barrel 18 of the firearm 10. The base portion 26 is configured to receive the barrel 18 of the firearm 10 therein. The base portion 26 is not attached to the barrel 18.
The extension portion 28 is attached to the base portion 26 and is supported by the base portion 26. The extension portion 28 is configured to receive and support the muzzle attachment 24. The extension portion 28 extends forward (i.e., longitudinally away from the buttstock 13) from a forward surface 30 of the base portion 26. The base portion 26 is closer to the butt stock 13 of the firearm 10 than the extension portion 28 when the muzzle adapter 22 is properly attached to the handguard 17 of the firearm 10 such that the extension portion 28 extends forward from the base portion 26 and the base portion 26 is rearward of the extension portion 28. In one embodiment, the extension portion 28 is integral with the base portion 26, and in another embodiment, the extension portion 28 threading engages the base portion 26.
The base portion 26 has a bore 32 extending therethrough that is centered about the longitudinal axis 34. The extension portion 28 also has a bore 32 extending therethrough. The bore 32 of the base portion 26 and the bore 32 of the extension portion 28 are in fluid communication with one another. The bore 32 through the extension portion 28 has a diameter at least as large as a diameter of the bore 32 through the base portion 26. In one embodiment, the board 32 through the extension portion 28 has a diameter greater than the diameter of the bore 32 at the base portion 26 such that the bore 32 through the muzzle adapter 22 flares outward toward a forward most surface 50 of the extension portion 28. The bore 32 is sized and shaped to receive the barrel 18 and allow the barrel to reciprocate therein during cycling of the firearm 10. The bore 32 of the muzzle adapter 22 is coaxial with the longitudinal axis 34 of the barrel 18 when the muzzle adapter 22 is secured (i.e., attached) within the handguard 17.
In one embodiment, the base portion 26 of the muzzle adapter 22 is sized so that an exterior circumferential surface 38 of the base portion 26 can be received inside a forward end of the handguard 17. The exterior surface 38 of the base portion 26 may be generally annular or disc shaped, but the exterior surface may also contain significant voids about the exterior to reduce weight or for the purposes. For example, base portion 26 may have a rear plan view relative to the longitudinal axis 34 that resembles a plus sign with a hole in the middle (i.e., the bore 32), a Mercedes Benz® logo with a hole in the middle (i.e., the bore 32), or a Maltese cross with a hole in the middle (i.e., the bore 32). In one embodiment, the exterior surface 38 is threaded and an inside surface of the handguard 17 has corresponding threads such that the base portion 26 can attach to the handguard 17 via screwing into the handguard 17. In other embodiments, the exterior surface 38 of the base portion 26 is not generally circular or arcuate, but is instead a plurality of flat surfaces (e.g. a plus sign with a bore 32 therethrough) configured to engage corresponding flat surfaces of the inside of the handguard 17.
In one embodiment, one or more threaded apertures 40 are defined in the exterior circumferential surface 38 of the base portion 26. The apertures 40 extend radially outward from a center of the base portion 26 (e.g., from the longitudinal axis 34 when installed in the handguard 17). The apertures 40 are positioned around the exterior circumferential surface 38 so as to align with corresponding counterbored (i.e., chamfered or beveled) access holes 42 through the handguard 17 when the muzzle adapter 22 is installed in or attached to the handguard 17. Threaded fasteners 44 are threaded into the apertures 40 of the base portion 26 through the access holes 42 in the handguard 17 when the muzzle adapter 26 is installed in the forward end of handguard 17 to releasably secure or attach the muzzle adapter 22 within the handguard 17. Although the muzzle device 20 is depicted in
In one embodiment, the extension portion 28 of the muzzle adapter 22 is tapered from a point forward of the forward surface 30 of the base portion 2 to the forward surface 50 of the extension portion 28. More particularly, at least a portion of the extension portion is tapered forward of the forward surface 30 of the base portion 26 to facilitate engagement with the muzzle attachment 24 (i.e., insertion into the muzzle attachment 24). In one embodiment, an exterior circumferential surface 36 of the extension portion 28 is threaded. In one embodiment, the threaded portion of the exterior circumferential surface 26 of the extension portion 28 has a larger diameter than at the forwardmost surface 50 of the extension portion 28 such that the extension portion has a smaller cross sectional diameter relative to the longitudinal axis 34 at the forward surface 50 of the extension portion than at the threaded portion of the external circumferential surface 36 and/or at the forward surface 30 of the base portion 26. The extension portion 28 has an exterior diameter less than that of the base portion 26 such that a forward surface 30 of the base portion 26 extends radially outward from a rear end of the extension portion 28 like a flange, as best shown in
The extension portion 28 of the muzzle adapter 22 has a length and a forwardmost surface 50 defining a plane 52 perpendicular to the longitudinal axis 34. Referring now to
