MOUNTINGS FOR SMALLARMS OR ORDNANCE ## Abstract A novel locking mechanism for a noise suppressor mount for a firearm comprising a muzzle attachment comprising a plurality of locking positions, a collar, and a locking arm comprising a locking notch wherein the collar rotates to move the locking notch in a circular direction into a locking position. ## Claims ### Claim 1 A noise suppressor locking mechanism for a firearm, comprising: a muzzle attachment comprising a plurality of locking positions; a collar; a locking arm comprising a locking notch; and wherein if the locking notch is misaligned with any of the plurality of locking positions and rests between two adjacent locking positions of the plurality of locking positions when the collar is initially engaged with the muzzle attachment and with a noise suppressor, the collar rotates to move the locking notch in a circular direction into one of the two adjacent locking positions, wherein when the locking notch is in a first position relative to the two adjacent locking positions, rotating the collar counterclockwise causes the locking notch to move in a clockwise direction, wherein when the locking notch is in a second position relative to the two adjacent locking positions, rotating the collar counterclockwise causes the locking notch to move in a counterclockwise direction, wherein the collar comprises a proximal end, and wherein rotation of the collar and rotation of the locking notch in the clockwise or counterclockwise direction are viewed from the proximal end of the collar. ### Claim 2 (depends on 1) The noise suppressor locking mechanism of claim 1, wherein the locking arm pushes the locking notch into the one of the two adjacent locking positions. ### Claim 3 (depends on 1) The noise suppressor locking mechanism of claim 1, wherein the locking arm pulls the locking notch into the one of the two adjacent locking positions. ### Claim 4 (depends on 1) The noise suppressor locking mechanism of claim 1, wherein the muzzle attachment further comprises a first threaded interface, wherein the noise suppressor comprises a proximal end cap, wherein the proximal end cap comprises a second threaded interface, wherein the noise suppressor further comprises a third threaded interface, wherein the collar comprises a fourth threaded interface, and wherein the collar is initially engaged with the muzzle attachment and with the noise suppressor by joining the first threaded interface with the second threaded interface and by joining the third threaded interface with the fourth threaded interface. ### Claim 5 (depends on 4) The noise suppressor locking mechanism of claim 4, wherein the first threaded interface and the second threaded interface, when joined with each other, comprise a primary locking mechanism, and wherein the collar rotating to move the locking notch in the circular direction into the one of the two adjacent locking positions comprises a secondary locking mechanism. ### Claim 6 A method of attaching a noise suppressor to a muzzle attachment, the method comprising: attaching the muzzle attachment to a firearm, wherein the muzzle attachment comprises a plurality of locking positions; attaching a noise suppressor to the muzzle attachment utilizing a locking mechanism comprising a collar, a locking arm, and a locking notch; and rotating the collar to move the locking arm and the locking notch in a circular direction into one of two adjacent locking positions of the plurality of locking positions, if the locking notch is misaligned with any of the plurality of locking positions and rests between the two adjacent locking positions when the collar is initially engaged with the muzzle attachment and with the noise suppressor, wherein when the locking notch is in a first position relative to the two adjacent locking positions, rotating the collar counterclockwise causes the locking notch to move in a clockwise direction wherein when the locking notch is in a second position relative to the two adjacent locking positions, rotating the collar counterclockwise causes the locking notch to move in a counterclockwise direction, wherein the collar comprises a proximal end, and wherein rotation of the collar and rotation of the locking notch in the clockwise or counterclockwise direction are viewed from the proximal end of the collar. ### Claim 7 (depends on 6) The method of claim 6, wherein the locking arm pushes the locking notch into the one of the two adjacent locking positions. ### Claim 8 (depends on 6) The method of claim 6, wherein the locking arm pulls the locking notch into the one of the two adjacent locking positions. ### Claim 9 (depends on 6) The method of claim 6, wherein the muzzle attachment further comprises a first threaded interface, wherein the noise suppressor comprises a proximal end cap, wherein the proximal end cap comprises a second threaded interface, wherein the noise suppressor further comprises a third threaded interface, wherein the collar comprises a fourth threaded interface, and wherein the collar is initially engaged with the muzzle attachment and with the noise suppressor by joining the first threaded interface with the second threaded interface and by joining the third threaded interface with the fourth threaded interface. ### Claim 10 (depends on 9) The method of claim 9, wherein the first threaded interface and the second threaded interface, when joined with each other, comprise a primary locking mechanism, and wherein the collar rotating to move the locking notch in the circular direction into the one of the two adjacent locking positions comprises a secondary locking mechanism. ### Claim 11 A noise suppressor locking mechanism for a firearm, comprising: a primary locking mechanism between a muzzle attachment and a noise suppressor; a secondary locking mechanism between the muzzle attachment and the noise suppressor, the secondary locking mechanism being different from the primary locking mechanism; a collar; wherein the primary locking mechanism when actuated causes the collar to initially engage with the muzzle attachment and with the noise suppressor; and wherein the secondary locking mechanism when actuated causes the collar to lock with respect to the muzzle attachment and with respect to the noise suppressor when contact points between the collar and the muzzle attachment are misaligned when the collar is initially engaged with the muzzle attachment and with the noise suppressor. ### Claim 12 (depends on 11) The noise suppressor locking mechanism of claim 11, wherein: the muzzle attachment comprises a plurality of locking positions; the collar comprises a locking arm comprising a locking notch, wherein the contact points between the collar and the muzzle attachment comprise the locking notch and at least one of the plurality of locking positions; the primary locking mechanism comprises a first threaded interface, which is part of the muzzle attachment, that engages with a second threaded interface, which is part of the noise suppressor; and the secondary locking mechanism comprises the locking notch engaging with one of two adjacent locking positions of the plurality of locking positions if the locking notch is misaligned with any of the plurality of locking positions and rests between the two adjacent locking positions when the collar is initially engaged with the muzzle attachment and with the noise suppressor. ### Claim 13 (depends on 12) The noise suppressor locking mechanism of claim 12, wherein the locking arm pushes the locking notch into the one of the two adjacent locking positions. ### Claim 14 (depends on 13) The noise suppressor locking mechanism of claim 13, wherein the collar comprises a proximal end, wherein the collar rotates counterclockwise, which causes the locking notch to move in a clockwise direction as viewed from the proximal end of the collar. ### Claim 15 (depends on 12) The noise suppressor locking mechanism of claim 12, wherein the locking arm pulls the locking notch into the one of the two adjacent locking positions. ### Claim 16 (depends on 15) The noise suppressor locking mechanism of claim 15, wherein the collar comprises a proximal end, wherein the collar rotates counterclockwise, which causes the locking notch to move in a counterclockwise direction as viewed from the proximal end of the collar.
