发明名称 Barrel vibration dampening device for rifles
摘要 A vibration dampening device 10 is provided in the forearm 14 of a rifle 10 for engaging a cantilevered barrel 12 forward of the rifle action for dampening the vibration of the barrel as a bullet moves through the barrel to the muzzle. The vibration dampening device in the preferred embodiment includes an insert 44 that is mounted in a cavity 38 formed in the forearm 14. The insert includes a threaded bore 48 with a pressure screw 50 threadably mounted in the bore 48 in which the threaded screw has a pointed end 54 engaging the barrel at a selected point. A tool access aperture 58 extends through the forearm from the lower profile surface 16 in alignment with the threaded bore 48 for enabling a tool to be inserted through a tool access aperture 58 to engage the pressure screw 50 to rotate the pressure screw to the desired position. Preferably a locking means 60 is provided for locking the pressure screw 60 in place when the correct pressure is obtained.
