Sound reducing systems for use with projectile launchers

A cassette for deploying one or more entangling projectiles, the cassette comprising:

• a pair of sockets, each socket being in fluid communication with a pressure source;
• an entangling projectile including a pair of anchors connected by a tether, each of the pair of anchors being positionable within one of the sockets and the tether being carried by the cassette;
• each socket carrying a slidable piston positionable in a respective socket between an entangling projectile and the pressure source such that each slidable piston is propelled along a respective socket in response to a pressure wave generated by the pressure source to thereby expel the anchor from the socket;
• and
• a pair of retaining clips, each engageable with an anchor and with a socket to aid in retaining the respective anchor in the respective socket prior to generation of the pressure wave;
• each socket including a piston stop positioned at an end of the socket, each piston stop preventing a respective piston from exiting a respective socket, and wherein each retaining clip includes at least one arm that engages a respective piston stop.
