- Muzzle brakes or recoil compensators are known, which redirect propellant gases to counter recoil when a firearm is fired.
- a flash suppressor is a known device attached to the muzzle of a rifle that reduces its visible signature while firing by cooling or dispersing the burning gases that exit the muzzle, a phenomenon more often associated with carbine length weapons.

Description
- This application is a continuation-in-part of co-pending U.S. patent application Ser. No. 14/719,861 filed May 22, 2015, and claims priority to and the benefit of U.S. Provisional Patent Application No. 62/050,478, filed Sep. 15, 2014.
- This invention relates to a device, attachable to the open forward end of a Krinkov-type muzzle brake, for providing a modular firearm noise suppressor or silencer.
- Muzzle brakes or recoil compensators are known, which redirect propellant gases to counter recoil when a firearm is fired. Likewise, a flash suppressor is a known device attached to the muzzle of a rifle that reduces its visible signature while firing by cooling or dispersing the burning gases that exit the muzzle, a phenomenon more often associated with carbine length weapons. A number of different flash suppressing designs have been used over the years. The simplest is a cone placed on the muzzle end of the barrel, which was used during World War II on jungle-combat versions of the Lee-Enfield, No. 5 variant, or the M1 Carbine. Pronged or birdcage type flash suppressors have also been used, which radially disperse burning gases rapidly exiting the muzzle.
- Another type of flash suppressor, which may also aid in reliability by increasing back pressure, is patterned after the Krinkov brake found on the Soviet AK74SU submachine gun. The Krinkov brake provides an expansion chamber with a cone-shaped exit nozzle. Other later devices, such as the KX3 flash suppressor sold by Noveske Rifleworks, LLC of Grants Pass, Oreg., have rearranged the Krinkov brake to position a chamber around the cone, shortening the overall length of the muzzle device. A Krinkov-type brake is not considered a noise suppressor, also known as a silencer, because, although it has a chamber, it simply redirects the blast that causes sound pressure waves forward and does not have a separate end cap or wall forward of the inner cone.
- Under United States law, flash suppressors, muzzle brakes, and compensators are treated differently from noise suppressors. Firearms noise suppressors are regulated as firearms under the National Firearms Act of 1934 and require registration and payment of a transfer tax. Although some states regulate the use of flash suppressors, the use of muzzle brakes and compensators generally are not restricted.
- Many types of firearm noise suppressors are available, including some that attach to or over various muzzle devices, including, and combination devices. All of those muzzle devices break up or redirect propellant gasses exiting the muzzle laterally. A Krinkov-type brake inherently has a large diameter forward opening or “bell” that is not conducive to attachment of a noise suppressor. The present invention is intended to improve on these designs and to provide a modular noise suppression unit that can be attached to the forward end of a Krinkov-type brake.
- Disclosed is a firearm noise suppressor for use with a muzzle brake of the type having a body and a substantially conical wall therein together defining an inner chamber and a substantially open forward end, also commonly known as a Krinkov-type brake. The noise suppressor includes a housing that is removably attachable at a rearward end to the forward open end of the muzzle brake. The housing includes a peripheral wall and a forward end wall having an outlet sized and positioned to allow a projectile to pass. At least one baffle is positioned in the housing and defines at least two inner chambers within the housing when attached to the muzzle brake. The at least one baffle may include a substantially conical portion that extends at least partially into the open front end of the muzzle brake.
- Other aspects, features, benefits, and advantages of the present invention will become apparent to a person of skill in the art from the detailed description of various embodiments with reference to the accompanying drawing figures, all of which comprise part of the disclosure.

In some instances, well-known structures, materials, or operations may not be shown or described in detail to avoid obscuring aspects of the embodiments.
- Referring to the various figures of the drawing, and first to
FIGS. 1-6 , therein is shown at 10 a flash suppressing muzzle brake device of the present invention. Thedevice 10 includes a substantially cylindricalmain body housing 12 with arear end portion 14 adapted to be secured, such as by threading, onto the muzzle of a firearm barrel 16 (shown inFIG. 6 ). Therear portion 14 may be internally threaded to match threads provided at the muzzle end of abarrel 16 and may includeflats 18 to facilitate tightening themain body housing 12 to the threaded connections. If desired, apin 20 may be used to permanently secure thedevice 10 to thebarrel 16. - The
device 10 includes aninner body member 22 having a substantially conicalforward portion 24 and arear portion 26 provided with a plurality of elongatedradial ports 28. Theinner body member 22 is held in place in aninner chamber 30 of themain body housing 12 by afront cover member 32. When assembled, theinner chamber 30 is defined by themain body housing 12, the exterior of theinner body member 22, and thefront cover member 32, as best seen inFIGS. 5 and 6 . - The
front cover member 32 may include a series ofexternal threads 34 configured to match a series ofinternal threads 36 on the interior of themain body housing 12. Thefront cover member 32 is configured on the inside to receive and support aforward rim 38 of thecone portion 24. Themain body housing 12 may also include an internalannular recess 40 adjacent therear end portion 14 to receive therear portion 26 of theinner body member 22. When thefront cover member 32 is threaded into engagement with themain body housing 12, theinner body member 22 is secured in compression therebetween, as shown inFIG. 6 . Specifically, theinner body member 22, provides a passageway axially aligned with thebore 42 of thefirearm barrel 16 when mounted. At therear portion 26 of theinner body member 22 there is achamber area 44 into which a projectile enters as it first exits the muzzle of thefirearm barrel 16. Thechamber area 44 includes a plurality ofradial ports 28 which control the rapidly expanding and high pressure gases being ported into theinner chamber 30 of themain body housing 12. At least a portion of the muzzle blast impacts a rearward facingannular wall 46 at the forward end of thechamber area 44. Theradial ports 28 may be in the form of elongated slots, which, if desired, may extend substantially the full axial length of therear portion 26 and be opened at the rearward most end. Also if desired, the length of theradial ports 28 may be angled or helically configured in the direction of rotation of the exiting projectile. For example, the helical orientation of theradial ports 28 may be made to correspond with the twist rate and direction of the rifling (not shown) in thebore 42 of thefirearm barrel 16. The high pressure flow of gasses passing through theradial ports 28 into theinner chamber 30 of themain body housing 12 impacts forward walls of thatchamber 30 to partially counteract the recoil forces of the firearm. - Forward of the
chamber area 44 and in axial alignment with thebore 42 of thebarrel 16, is apassageway 48 which is sized to be only slightly larger in diameter than the projectile to be fired from thebarrel 16. Thepassageway 48 diameter should be kept as small as practical, while avoiding possible contact with the projectile. Forward of thepassageway 48 is theconical portion 24 of theinner body member 22 defining a substantiallyconical chamber 50 with a fully openforward end 52. As high velocity gases pass through thecentral passageway 48 and enter theconical chamber 50, the stream is pulled toward the conical interior walls by the Coanda Effect (the tendency of a fluid jet to be attracted to a nearby surface). This causes the high velocity stream of gases to expand rapidly in cross-sectional area, which results in a corresponding rapid drop in fluid stream pressure and dissipation of the burning gasses that cause muzzle flash. - The forward end of the
front cover member 32 may be made with an annular series ofspikes 54, which provide a crenellated strike surface on themuzzle device 10. If desired, afront cover ring 56 may be provided to cover thespikes 54 to guard against inadvertent contact with or injury to nearby persons or objects. Thecover ring 56 may be internally threaded 58 to correspond with theexternal threads 34 of thefront cover member 32. Also if desired, at least a portion of the exterior surface of thefront cover ring 56 may be provided withknurling 60 to facilitate grip when removing. Alternatively, aglass brake attachment 62 may be threaded on to thefront cover member 32. Theglass break attachment 62 provides one or more forwardly-extendingelongated tines 64 with hardened, sharp ends that can be used as an impact tool. - Referring now in particular to
FIG. 7 , if desired, the rearward edge of thefront cover member 32 may be provided with one ormore tabs 66 or notches to provide grip in the event theexternal threads 34 of thefront cover member 32 become stuck with theinternal threads 58 of the front cover ring 56 (shown) or the glass brake attachment 62 (not shown). - Also if desired, a series of
dimples 68 or depressions may be formed over at least a portion of the outer surface of themain body housing 12 in order to increase the surface area for enhanced heat dissipation. - Referring now to
FIGS. 8-10 , therein is shown at 70 a firearm noise suppressor that is mountable directly to the forward end of amuzzle brake 10 of the type described above. Thedevice 70 includes atubular body 72 with an openrear end 74 and a forward wall orend cap 76. Thebody 72 may be provided withinterior threads 78 adjacent the openrear end 74 that will mate with theexternal threads 34 on thefront cover member 32 of themuzzle brake device 10. As shown inFIG. 8 , thesuppressor 70 may be attached in lieu of thefront cover ring 56 or other assessory for themuzzle brake device 10 and thebody 70 may be sized to match the size and shape of themain body housing 12 of thebrake 10. - Because the
tubular body 72 of thesuppressor 70 does not include any rear wall or end cap, it cannot be mounted directly to the muzzle of a firearm barrel and is incomplete to function as a firearm noise suppressor. Other types of muzzle brakes to which other firearm noise suppressors may be mounted include lateral ports through which propulsion gases are diverted and expelled. For this reason, suppressors that fit over such muzzle brakes must be designed to attach rearward of those lateral ports in order to contain the laterally-diverted gas flow. One such example is shown in U.S. Patent Application Publication No. 2013/0340313, published Dec. 26, 2013. The Krinkov-typemuzzle brake device 10 described above includes only one, enlarged and forwardly-directed opening through which propulsion gases are expelled. In the form described above, themuzzle brake 10 does not reduce the sound of the firearm discharge, but merely redirects it in a forward direction. - The interior of the
tubular body 72 includes one or more baffles which divide the interior into a plurality ofchambers 82 behind the front wall orend cap 76. Each of thebaffles 80 and theforward wall 76 includes acentral opening central passageway 48 and bore 42 of thefirearm barrel 16 so that a projectile expelled from thebarrel 16 is allowed to pass closely, but without interference or contact. A wide variety of shapes, styles or designs may be used for thebaffles 82 in the present invention. The exact design or number of thebaffles 82 is not pertinent to the present invention, only their position within thetubular body 72. Likewise, the length and/or diameter of thetubular body 72 may be varied as necessary to accommodate a selected number or size of baffles, depending on the caliber of the firearm on which it is to be used and the degree of noise suppression desired. - If the
muzzle brake 10 includes a portion that projects forwardly of the location of theexterior threads 34, thetubular body 72 must extend sufficiently rearward of thebaffles 80 in order to attach and accommodate the forward projection, as shown in the illustrated embodiment. At the same time, because the forward end of a Krinkov-type muzzle brake has a large openforward end 52 andconical chamber 50, thebaffles 80 may include an elongated conical shape that takes advantage of and extend into this open area at the front of thebrake 10. - Accordingly, the present invention provides a relatively low cost unit that can be attached with ease and modularity to a Krinkov-type muzzle brake. As discussed above, the sale, possession and use of muzzle brakes is generally not restricted by state and federal laws. The modular noise suppressor, which is subject to registration and a transfer tax through an extended procedure, may be added at a later time.
- When the
suppressor unit 70 assembled onto themuzzle brake 10, the openforward end 52 of theconical chamber 50 is enclosed. In this configuration, theconical forward portion 24 of theinner body member 22 becomes a baffle and theinner chamber 30 andconical chamber 50 of themuzzle brake device 10 become baffle chambers contributing to the overall noise suppression effect of the assembled unit. - While one embodiment of the present invention has been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. Therefore, the foregoing is intended only to be illustrative of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not intended to limit the invention to the exact construction and operation shown and described. Accordingly, all suitable modifications and equivalents may be included and considered to fall within the scope of the invention, defined by the following claim or claims.
