Com­mon Air­gun De­signs

Modern Pioneer - - Squirrel -

The Gamo Swarm Maxxims used in the 2017 Gamo Squir­rel Mas­ter Clas­sic com­pe­ti­tion are of the break-bar­rel, spring-pis­ton de­sign, which re­quires the shooter to hand cock the ri­fle be­tween each shot. The Swarm is unique be­cause it’s the only cur­rently pro­duced break-bar­rel ri­fle to come with a mag­a­zine. The break-bar­rel de­sign is pos­si­bly the most pop­u­lar and re­li­able of all air­gun de­signs to­day.

The pre-charged pneu­matic (PCP) is grow­ing in pop­u­lar­ity, how­ever, due to its re­peat­ing-shot ca­pa­bil­i­ties, fre­quently faster ve­loc­i­ties and some­times larger avail­able cal­ibers. As the name im­plies, PCP air­guns must be precharged with air.

To a cer­tain de­gree, CO2 pel­let guns have lost pop­u­lar­ity in re­cent years, but are still be­ing pro­duced. This de­sign re­quires the use of a small, pre-charged CO2 can­is­ter to pro­pel pel­lets.

Last on the lad­der are the vari­able-pump models, which must be pumped up to pro­pel their pel­lets. Their only ad­van­tage is that pel­let ve­loc­ity can be var­ied based upon how many times the gun is pumped.
