GBBCustom Apex Aluminum Outer Barrel For Elite Force Gen 4. GLOCK 17 / 18

The GBBCustom Apex Outer Barrel is the first of its kind. It is the first airsoft barrel designed in the USA for the specific needs of Milsim and Speedsoft players. These barrels are made of high-quality 6061 aluminum and are anodized for a smooth radiant finish. Each barrel comes with a matching thread adapter and thread protector. This was done to allow the user to swap between 14mm-, 14mm+. and 11mm+ (additional adapters sold separately). Lastly, each barrel was engraved with stylish markings to complete the look of your custom airsoft replica.
