A performance enhancing and force absorbing dental appliance adapted to lie within the mouth of an athlete consists of an occlusal posterior pad made of quadruple composite material comprising four layers of distinct materials, further comprising a first layer of a durable, resilient material; a second layer of non-softenable, flexible material; a third layer of a hard, very durable material; and a fourth layer of a softenable material, engageable with the occlusal surfaces to space apart the upper and lower teeth, to absorb shock and clenching stress. An adjustable arch adapted to expand and contract to be molded to the palate is provided connecting the posterior pads together within the mouth and out of the way of the tongue to maintain the position of the occlusal posterior pads within the mouth during use and to prevent loss of the pads such as by swallowing. An expandable serpentine bridge may be embedded in the arch.

A gas-powered gun according to claim 1 wherein said sear member is pivotably mounted and said sear mechanism includes spring means for biasing said sear member into engagement with said hammer so as to hold said hammer in said rear, cocked position. 3. A gas-powered gun according to claim 2 wherein said sear mechanism includes a pivot pin located at a central section of said sear member, said pivot pin defining a pivot axis about which said sear member can pivot and wherein said spring means engages a rear end section of said sear member while said sear engaging member of the solenoid is positioned to engage a front end section of said sear member. 4. A gas powered gun according to claim 1 wherein said sear engaging member is movable linearly along an axis of movement that extends at a substantial acute angle of more than 45 degrees to a central axis of said barrel. 5. A gas powered gun according to claim 1 wherein said barrel includes a ball-holding open-ended chamber at said rear end thereof and when said ball is advanced to said firing position by said bolt, said ball is positioned at least to a major extent in said chamber in said barrel. 6. A gas-powered gun for firing balls dispensed from a magazine into the gun, said gun adapted to be connected to a source of pressurized gas, said gun comprising: a gun body including a gun handle and a breech section; a barrel, said breech section being connected to a rear end of said barrel and capable of receiving one ball at a time through a ball feed port from said magazine; a bolt slidable within the breech section to advance a ball to a firing position and close off said feed port; a hammer slidable in a chamber formed in said gun body; means for biasing said hammer towards a forward firing position; a trigger movably mounted on said gun body; an electronic control circuit including a switch operable by said trigger, said circuit being adapted for connection to a power source; a sear mechanism including a pivotable, elongate sear member movably mounted in said body and adapted to engage and hold said hammer in a rear, cocked position, said sear mechanism further including a pivot pin located at a central location on said sear member, said pivot pin defining a pivot axis about which said sear member can pivot, and spring means for biasing said sear member into engagement with said hammer so as to hold said hammer in said rear, cocked position, said spring means engaging a rear end section of said sear member, said sear mechanism also including a relief pin mounted rigidly in said gun body below said sear member and acting to limit downward pivotal movement of said sear member caused by said spring biasing means; a solenoid mounted in said gun body, operated by said control circuit, and adapted to move said sear mechanism so as to release said hammer when said trigger is pulled, said hammer when released sliding rapidly to its forward firing position, said solenoid including a sear engaging member movable from a lowered position corresponding to the cocked position of said hammer to a raised firing
