Patent attributes
Apparatus and associated methods relate to a gun barrel liner having circumferentially distributed radially yielding inserts. In an illustrative example, the inserts may be distributed along a longitudinal axis of a liner body. For example, each of the inserts may be urged radially inward against the liner by one or more coupling members. Each coupling member may, for example, circumscribe a circumference of the liner. Inserts may, for example, be individually assembled onto a liner. Inserts may, for example, be coupled to spacers such that an insert assembly may be assembled onto a liner as a single unit. For example, the inserts may yield to a radially outward force from a projectile such that an effective diameter of the gun barrel liner substantially conforms to the diameter of the projectile. Various embodiments may advantageously provide interchangeable radially yielding gun barrel liners.
