US12523442 - Rifle with tapered interfaces

A rifle with tapered interfaces has a receiver, a barrel extension connected to the receiver at a first interface, a barrel connected to the barrel extension at a second interface, a barrel nut element connected to the barrel extension at a third interface and to the barrel at a fourth interface, and at least two of the first, second, third, and fourth interfaces being tapered interfaces. The tapered interfaces may be stably tapered such that a wedging effect is generated. The barrel extension may have two tapered interfaces. The barrel extension may have a forward external tapered interface connecting to the barrel nut element and a forward internal tapered interface connecting to the barrel.

The patent describes a rifle design featuring multiple tapered interfaces between the receiver, barrel extension, barrel, and barrel nut element, which enhances stability through a wedging effect. At least three of these interfaces are tapered, potentially improving the overall structural integrity and alignment of the firearm components.
