Abstract
In a spring piston airgun, a compression piston is provided for longitudinal translation within a compression tube in response to a motive force. The compression piston includes a main piston body and a piston head, wherein the piston body and piston head are coupled for partial independent translation along a longitudinal axis. A resilient compressible bushing is longitudinally intermediate a portion of the piston body and the piston head, such that upon a deceleration of the piston head, the piston body is not immediately acted upon by the deceleration, rather the bushing absorbs a portion of the deceleration and radially expands to contact the compression tube.
