Airsoft Gun Upgrade & Maintenance Parts

Keep Your Airsoft Gun In Top Condition!

Airsoft GI has been the leading North American airsoft parts store since 2003, and here you’ll find everything you could possibly imagine for routine maintenance, emergency repairs and performance airsoft upgrades. We have the largest selection of parts and accessories for taking care of your favorite airsoft gun or rebuilding an older model. Our OEM replacement section has genuine factory airsoft parts that come directly from the manufacturer, and we have plenty of aftermarket parts as well from top brands to enhance performance and improve playability. In addition, we have an assortment of airsoft tools for sale that makes it easier to work on your gun. Choose a subcategory or browse our complete inventory below to get started.

We’ve made it simple to find exactly what you need for your airsoft gun at a price you can afford. Our OEM section allows you to select a specific manufacturer so you only see the parts that actually fit your gun. So whether you need airsoft gun parts from Elite Force, KWA, ICS, PolarStar or another manufacturer, just click the link to go to that section. Our upgrades are split into internal and external categories, and from there you can narrow down to rail sections, reinforced body pins, AEG gearboxes and numerous other options. Go to our tools and tech products subcategory to find wrenches, pin extractors, lubricants and other airsmith necessities for your next project.

Of course, we know not everyone has the time, skills or workspace to do their own airsoft upgrades. That’s why we offer a number of affordable packages that tailor your equipment to various weapon preferences and combat environments, from field durability to Mil-sim support gunner upgrades. If you’re looking to learn about the workings of airsoft guns, our boneyard is a great place to start. The semi-working and non-working guns in this section can be salvaged for parts or used as a tech training tool. Whatever you order, you’ll get free shipping on all orders more than $60, plus a price match guarantee, full tech support and all the other benefits of shopping with the premier airsoft parts retail seller.
