Quick-disconnect positive muzzle mounting mechanism

Abstract

Provided is a quick-disconnect muzzle mounting mechanism having a mount fixture and a coupling assembly. The mount fixture is fixable to the muzzle end of a firearm barrel and includes a plurality of substantially radial lugs. The coupling assembly is fixable to a muzzle device and includes a first part with a non-round opening adapted to axially receive the lugs of the mount fixture and a second part axially adjustable relative to the first part to clamp the lugs therebetween.

What is claimed is: 
     
         1 . A quick-disconnect muzzle mounting mechanism, comprising:
 a mount fixture fixable to the muzzle end of a firearm barrel and including a plurality of substantially radial lugs;   a coupling assembly fixable to a muzzle device, the coupling assembly including a first part with a non-round opening adapted to axially receive the lugs of the mount fixture before rotating to engage the lugs and a second part axially adjustable relative to the first part to clamp the lugs therebetween.   
     
     
         2 . The mounding mechanism of  claim 1 , wherein the first part includes recesses for receiving each of the lugs after rotating to engage the lugs. 
     
     
         3 . The mounding mechanism of  claim 1 , comprising at least one primary pair of lugs oriented in a substantially diametrically opposed position. 
     
     
         4 . The mounding mechanism of  claim 3 , comprising a secondary pair of lugs each lug circumferentially aligned with and axially spaced from a corresponding primary lug. 
     
     
         5 . The mounding mechanism of  claim 1 , comprising three circumferentially spaced lugs. 
     
     
         6 . The mounding mechanism of  claim 5 , wherein at least one lug is unequally spaced from the other lugs. 
     
     
         7 . The mounding mechanism of  claim 1 , comprising an internal detent means between the first and second parts. 
     
     
         8 . The mounding mechanism of  claim 1 , comprising a hub that is threadingly engaged relative to at least one of the first and second parts to adjustably clamp the lugs after rotating to engage the lugs. 
     
     
         9 . The mounding mechanism of  claim 8 , including a detent to releasably hold the hub in at least one position.
