A tank within the gun (looking much like a second or third barrel) is filled at home, from a SCUBA tank. The solution is pre-charged pneumatics (PCPs). No problem if you're target shooting, but what if you're hunting? Miss, and by the time you're ready again the quarry will be long gone! The negative aspect is the time it takes to prepare a multi-stroke rifle for a second shot. They can be compact and lightweight, too. The major benefit with pneumatic air rifles is very low recoil. High-end competition rifles compress enough air in a single pump, but more generally available “multi-stroke” models might take half a dozen pumps or more to build up sufficient pressure. Pneumatic air rifles (also called variable pump) usually use a manual pump action to compress air in a cylinder. With prices only a little above spring-piston models, they're definitely worth considering. However, several major manufacturers have announced intentions to make gas ram air rifles, so we're sure to see more of them. It's relatively new technology, and at the time of writing, not widely used. There's less recoil, and owners often claim they’re quieter. It's not affected by temperature, and it's easier to cock than a spring. The gas cartridge is a sealed unit, so it never needs refilling. Pulling the trigger releases the pressure in much the same way. Instead of loading up the spring pressure, a piston compresses gas in a cartridge. Gas ram air rifles (also gas piston or IGT – Inert Gas Technology) work on the same principle as spring-piston. Springs last a long time, and while they do wear eventually, they're not difficult to replace. Levers can also be underneath, above, or on the side. Pull the trigger and the spring releases, pushing a ram that forces high-pressure air behind the pellet, and thus along the barrel.īreak-barrel is just one piston method. You “break” the barrel, levering it open so you can put a pellet in the breach. ![]() Break-barrel models are very popular because they're easy to use and very repeatable. Spring-piston air rifles use a lever action. What differentiates each type of air rifle is the way the pressure is provided. Pulling the trigger releases pent-up energy, and fires the pellet down the barrel. All air rifles work in basically the same way: air (or gas) is pressurized.
