1. A gun barrel liner, comprising:
a liner body extending along a longitudinal axis; and,
a plurality of displaceable insert members distributed along the longitudinal axis of the liner body from a starting location towards a distal end of the liner body, wherein each of the plurality of displaceable insert members is coupled to the liner body by at least one elastically deformable urging member exerting a radially inward force on at least one corresponding displaceable insert members such that,
an internal surface of each of the plurality of displaceable insert members protrudes into a lumen defined by an inner surface of the liner body, and the internal surfaces of the plurality of displaceable insert members cooperate to form a compliant effective inner diameter (De) within the lumen less than an actual inner diameter (Da) of the lumen such that, when a projectile having a diameter Dp≥De travels through the liner body, the at least one elastically deformable urging member yields to a radially outward force from the projectile such that De=Dp≤Da.
