A barrel system for a paintball gun allows a user to quickly change the magna porting size of the barrel without the need to switch the barrel. A peg is located on an outer surface of the barrel as is a first port. A barrel tip has a second port aligned with a first channel and a third port of a different size relative to the second port, the third port aligned with a second channel. The barrel is received within the barrel tip so that the peg is either received within the first channel and thereby overlaying the second port with the first port, or the peg is received within the second channel and thereby overlaying the third port with the first port. An additional of port of yet another size as well as a null port may be provided, each with its own aligned channel.

A compliant interface for a wearable electronic device includes a three-dimensional lattice structure that is coupleable to the wearable electronic device and compressible to conform to one or more of a facial feature or an upper cranial feature of a user wearing the wearable electronic device. The compliant interface may be one of a facial interface of a head-mounted display unit, a head interface of a head-mounted display unit, or a head interface of a headphones unit. The three-dimensional lattice structure may be formed of silicone that may form less than 35% of a volume of the three-dimensional lattice structure in an uncompressed state. Compliance of the facial interface may vary by locations at which the compliant interface engages the user. The compliance may vary according to one or more of geometric stiffness or maximum deflection of the three-dimensional lattice structure.

A three-component barrel system for a paintball gun uses a barrel back that threadably couples to the gun. A barrel tip is magnetically coupled to the barrel back. A barrel insert, through which the paintballs are actually fired, is received within the hollow interior formed by the coupled barrel back and barrel tip. The barrel insert has porting thereon as does the barrel tip the two sets of porting correspond with one another. A channel within the barrel tip slidably receives a peg on an exterior of the barrel insert in order to assure proper alignment between barrel tip and barrel insert. The bore of the barrel insert can taper outwardly in proceeding from its breach end to its muzzle end.
