Lock/rotation mounted suppressor

Abstract

The present invention is directed to an adaptor for a suppressor comprising a gate for locking the suppressor on the muzzle and a threaded receiver for securing the suppressor to the firearm such that excessive play of the suppressor is removed. It is further directed to a method of securing a suppressor on a firearm by engaging a gate on an adaptor in a groove on a barrel of the firearm to lock on the adaptor, and any attached suppressor, and then tightening the suppressor and the adaptor on the barrel by threading the suppressor into the adaptor until excessive play is removed.

1 . A suppressor/adaptor assembly comprising:
 a. an adaptor comprising a adaptor threaded portion; and   b. a suppressor comprising a suppressor threaded portion,   wherein the suppressor is engaged with the adaptor when the two threaded portions are threadingly engaged such that when the assembly is tightened, a rotation lock engages a teethed ring to prevent the assembly from loosening.   
   
   
       2 . The assembly according to  claim 1 , wherein the adaptor further comprises a gate and a gate lock on a barrel engaging end of the adaptor. 
   
   
       3 . The assembly according to  claim 1 , wherein the adaptor threaded portion is a threaded receiver in a channel of the adaptor, and the suppressor threaded portion is a threaded neck portion. 
   
   
       4 . The assembly according to  claim 1 , wherein the suppressor threaded portion is a threaded receiver in a channel of the suppressor, and the adaptor threaded portion is a threaded neck portion, the suppressor further comprising a stopper capable of engaging the tip of a firearm barrel when the barrel is inserted into the channel of the adaptor. 
   
   
       5 . A suppressor adaptor comprising:
 a. a gate;   c. a channel; and   d. a threaded portion,   wherein the threaded portion of the adaptor is capable of threadingly engaging a threaded portion of a suppressor and the gate is capable of engaging a retaining groove on a barrel that has been inserted into the channel to lock the adaptor onto the barrel.   
   
   
       6 . The adaptor according to  claim 5 , wherein the retaining groove is on a retaining collar. 
   
   
       7 . The adaptor according to  claim 6 , wherein the retaining collar is a part of a flash suppressor. 
   
   
       8 . The adaptor according to  claim 5 , wherein the retaining groove is directly on a barrel. 
   
   
       9 . The adaptor according to  claim 5 , further comprising a rotation lock capable of engaging a corresponding teethed ring on the suppressor to prevent loosening of the suppressor from the adaptor, once the suppressor is tighteningly threaded -into the adaptor. 
   
   
       10 . The adaptor according to  claim 5 , further comprising a rotation lock capable of engaging a corresponding teethed ring on the suppressor to prevent loosening of the suppressor from the adaptor, once the suppressor is tighteningly threaded into the adaptor. 
   
   
       11 . The adaptor according to  claim 5 , further comprising a gate lock capable of engaging a groove in the gate to prevent the gate from separating from the adaptor. 
   
   
       12 . A method of attaching a suppressor on a barrel comprising:
 a. partially threading a suppressor to an adaptor having a gate on a barrel engaging end;   b. inserting a barrel having a gate retaining groove into the barrel engaging end of the adaptor;   c. engaging the gate with the gate retaining groove to lock the barrel within the adaptor;   d. tightening the suppressor to the adaptor,   wherein when the suppressor is tightened to the adaptor, a first push-pull force is created at an interface of a tip of the barrel and a part of the suppressor, and second push-pull force is created at an interface of the gate and the gate retaining groove.   
   
   
       13 . The method according to  claim 12 , wherein the suppressor has a threaded neck that is threadingly engaged with a threaded receiver of the adaptor to thread the suppressor on the adaptor. 
   
   
       14 . The method according to  claim 13 , wherein the suppressor part that engages the tip of the barrel is a inner stop shoulder. 
   
   
       15 . The method according to  claim 12 , wherein the suppressor has a threaded receiver that is threadingly engaged with a threaded neck of the adaptor to thread the suppressor on the adaptor. 
   
   
       16 . The method according to  claim 15 , wherein the suppressor part that engages the tip of the barrel is a stopper. 
   
   
       17 . The method according to  claim 12 , wherein the suppressor has a teethed ring, and the adaptor has a rotation lock, wherein the rotation lock is capable of engaging the teethed ring to prevent the threaded suppressor from loosening from the adaptor. 
   
   
       18 . The method according to  claim 17 , wherein the rotation lock is also capable of engaging the teethed ring to prevent the threaded suppressor from further tightening to the adaptor. 
   
   
       19 . The method according to  claim 12 , wherein the adaptor further comprises a gate lock capable of engaging a lock groove on a surface of the gate to prevent the gate from moving. 
   
   
       20 . The method according to  claim 12 , wherein the gate retaining groove on the barrel is on a retaining collar of a flash suppressor.
