20110000122 | DEVICE FOR PREVENTING DUST AND MOISTURE FROM ENTERING A FIREARM BARREL - A muzzle cover for a firearm comprising a soft, flexible and resilient member that slides over and frictionally engages the front end of the muzzle. The cover comprises a substantially cylindrical sheath that is open at a first end to receive the front end of the muzzle therein and which frictionally engages the external surface of the muzzle. A conical tip is integrally formed with the sheath and extends outwardly from the sheath and over the opening to the barrel. The conical tip may extend forwardly away from the front of the sheath or may be depressed inwardly into the bore of the sheath upon application of gentle pressure from a fingertip. The muzzle cover completely disengages from the muzzle when a projectile is fired from the weapon. | 01-06-2011 |
