If you’re in the market for a reliable shooting, quick firing air gun, consider a CO2-powered semi automatic air rifle. A distinct advantage of using CO2 is that you don’t have to stop and pump up your airgun before each shot. Just pop in a CO2 cartridge and you’re ready to go. Generally one 12 gram CO2 cartridge will give you about 50 shots before you have to change it out. However, this number can vary from airgun to airgun depending on the efficiency of the air rifle.
Semi automatic air rifles can be used to some degree for teaching gun safety, handling, and technique in a safer way than regular guns. But they can still pack a punch if pegged by one! With air guns looking more and more like real guns, there is usually a distinguishing mark on the end of the barrel (usually an orange tip). This is to prevent an unnecessary death should someone try to rob a bank with an air gun.
There is no hearing protection needed when firing semi automatic air rifles or other air guns. Proper safety measures would include only goggles usually. These types of guns are excellent for hunting small varmint, target shooting, and general practice for beginners. The ammunition required is also a plus because it is either inexpensive BBs or pellets.
The only real drawbacks to semi automatic air rifles are the lack of power they have compared to other spring or pump powered rifles. Some rifles shoot as high as 754 FPS or 600 FPS. While this is a decent power, pump and spring air rifles are capable of shooting at 700-1250 FPS.
Sale and possession of airguns is not regulated federally, nor are they regulated by most state and local governments. Ordinances in many cities do prohibit the discharge of air guns outdoors outside of an approved range though. Check with your local gun distributor to find the laws in your area.
