Features to Look for When Buying a Quiet Air GunWe all know that airgun manufacturers advertise high velocities on their boxes because to the uninitiated, velocity sells, it's kind of like bragging rights about your car's top speed. But honestly, even if your car can do 180 mph (289 kph) how often do you ACTUALLY drive at top speed? Your car gets horrible gas mileage at top speed, it's hard on the engine, and it doesn't perform well maxed out. The same goes for airguns. Making a pellet gun that can exceed the speed of sound can be done, but it uses a lot of air with each shot, and because of the buffeting of the air in the transonic range, (from about 900fps up to 1300fps) depending on the projectile shape and weight, the accuracy suffers greatly. Making a powerful airgun that is quiet can be difficult. Once you exceed the speed of sound (about 1130fps or 344mps at 72 degrees F.) the crack of the sonic boom behind the projectile cannot be silenced. With smaller calibers, if you can keep the projectile below the speed of sound the gun can be extremely quiet, up to a certain caliber. The breakover point seems to be.25 caliber, because of the volume of the air needed to drive larger projectiles, suppressing them effectively is very difficult. When shopping for an airgun that can be either quiet from the factory, or made quiet with an aftermarket moderator, you will typically want a gun that is.25 caliber and smaller, with a velocity of less than 1000fps. The length of a barrel has a lot to do with how quiet an airgun is, but that comes with its own caveats, a longer barrel will let you use the limited volume of air and air pressure efficiently, and give you more velocity to a point, but after a certain length, the velocity will start to fall off, unless you use MORE air to push the pellet down the longer barrel. Break barrel airguns can be suppressed as well, but as the shooter, you don't think it is quiet because of the noise the power plant makes is right by your face and the noise it makes is transmitted through the bones in your head. From 20 feet away, you would be surprised how quiet some break barrel airguns can be. To sum it up, when looking for a quiet airgun, you should be looking for a.25 caliber or smaller, with a medium length barrel, preferably with a shrouded barrel, or a good aftermarket moderator that matches the air volume your air rifle uses per shot, and ideally with a velocity of less than 900fps for maximum sound suppression.Can I Add a Suppressor to an Air Gun?The short answer is yes, but... These airguns are so quiet you won't need one. However, for louder airguns, let's continue. While dedicated airgun suppressors are not regulated at the federal level in the USA by the BATF (Bureau of Alcohol Tobacco and Firearms) they may be regulated by laws at your state or local level, or in your country if you live outside of the USA. Firearm suppressors are regulated by the BATF and require a special tax stamp, and an extensive background check, they also use a different thread pitch than airgun suppressors to deter the use of non-firearm designs being interchangeable. Some airguns that don't come with suppressors from the factory may have threaded muzzles or replacement muzzle caps that are threaded 1/2 UNF for airgun suppressors. Some airgun designs that do not have threads or can not be threaded because of their sights or sheet metal or plastic barrel shrouds can be fitted with aftermarket suppressors that have been designed and tested by enthusiasts using 3D printers. The 3D-printed suppressors will be made from plastic, and the end that attaches to the rifle can be designed and printed to fit almost any airgun on the market from a $30 Daisy to a $3000 Daystate. But before purchasing a suppressor for your airgun, check with your local municipality to see what the laws are in your area.What is the Quietest PCP Air Rifle for Hunting?If you ask 20 airgunners that question, you will likely get five different answers. The most popular answer will probably be the Benjamin Marauder in.22 caliber. Followed closely by the FX Impact M3 in.22 caliber. Side by side both rifles are very quiet, within a Db or so different on the meter, but they are two entirely different animals, aimed at two entirely different types of shooters. The Marauder can be had in either an all weather synthetic stock, or a wooden stock, and has a fully shrouded barrel that uses the volume of the shroud to dissipate the air blast exiting the barrel, and has internal baffles to reduce the muzzle blast even further, the mechanical noise of the gun operaating is somewhat absorbed by the wood or synthetic stock. The FX Impact M3, is almost entirely carbon fiber and metal, and acts like a tuning fork when fired, so there is little dampening of the mechanical noise. The M3 has a shrouded barrel with a DonnyFL moderator/suppressor on the end of the shroud, but the shroud is not actively used to quieten the rifle as the Marauder does. The M3 also has a more tactical design to the airgun, where the marauder has a more traditional design. The biggest difference is in the price, at the time of this writing, the Marauder sells for about $570, where the Impact M3 sells for $2200. The difference of the sound levels between the two rifles is negligible, but the differences of the price and shooting experience are worlds apart.
