  • Rifle gun barrel
    Patent number: 4211146
    Abstract: To increase the strength, rigidity and accuracy of a rifle gun barrel, a multi-part composite rifle barrel is created by enclosing the inner rifled tube with an outer sleeve, the two fastened together in a way that introduces compression in the outer part and tension in the inner part. The tension in the inner part increases the barrel's rigidity and reduces its vibration, thus increasing the accuracy of the rifle.
