Outer barrels are a cosmetic accessory that you can use to custom build your rifle. They are a great way to conceal a longer inner barrel to gain more range and accuracy. Check out our selection below!
Q: What is an outer barrel?
A: On a real firearm, a barrel is its own single component. On an airsoft gun, there are two barrels: an inner barrel and outer barrel. The inner barrel is the part that you don't see and is the section where the BB travels down and this component is responsible for your range and accuracy. The outer barrel is the part you do see, and is mimicking the look of the real firearm but has influence on how the gun shoots mechanically speaking.
Q: Why might I want to change my outer barrel?
A: Now that we've established that the only function for the outer barrel is cosmetic, let's talk about the goals of changing this out. People make modifications to their airsoft gun's outer barrel for numerous reasons. One thing people like to do is run mock suppressors. Some of these mock suppressors might conflict with your gun setup due to shapes of handguards and the suppressor itself. When you run into this situation you might want to change the outer barrel to a longer version if there is something compatible for your gun. Another thing you could do is run threaded barrel extensions which add length to your outer barrel.
Q: I've heard of people extending inner barrels. What is the purpose of doing this?
A: Some people like a smaller lighter gun but want to mimic the performance of a longer one. And the key difference in performance is the overall barrel length. Often times people may change over to the longer inner barrel or have a second hopup unit and barrel setup so that they can switch back and forth with minimal effort. This will get you some gains in velocity as a byproduct of a longer barrel but you do have an exposed section of barrel. This is bad because if you hit it into something you risk bending or damaging the inner barrel. So in order to protect that inner barrel you will want to either replace the outer barrel with a longer unit, extend your current outer barrel with an extension piece, or cover it up with a mock suppressor. This is a style choice so what you want to use is entirely up to you.
Q: I have X gun. What do I need to do this?
A: The use of universal extensions is probably the easiest item you can get that will add one to six inches of barrel length to your gun. Other than that, this will require some intense research on your part as some guns have many options and some guns have practically none. Installing aftermarket outer barrels will require some skill to take apart the airsoft gun. This is not an easy task that can be accomplished by beginners so do not tackle this on your own if you are inexperienced.
