Semi-auto rifles are a specialty here at Impact Guns. From kid-friendly guns such as the famous Ruger 10/22 to more advanced designs for home defense, long range shooting, and hunting- we carry them all. A semi-automatic rifle is a magazine fed rifle that automatically reloads another round into the chamber with each pull of the trigger. The king of semi-auto rifles is the venerable AR-15 (sometimes referred to as an AR15 or an M4)-- and with good reason. The AR-15 assault rifle (sometimes called a black rifle) is the modern civilian incarnation of the original M16 military rifle. It is a platform more-so than a gun model: there are hundreds of companies that manufacture parts and components for this platform, and we have dedicated areas for them: AR-15 Rifles For Sale and AR-15 Parts For Sale. The AK-47 is another popular model, again manufactured by many different companies today. These can be also be found in their own areas: AK-47 Rifles For Sale and AK-47 Parts For Sale. For plinking, home defense, hunting, long range shooting, or just plain fun-- Impact Guns has the semi-automatic rifle you are looking for!
