FPS - 360 AW Custom strives to provide Airsofters with high quality guns that come directly from the factory already upgraded. Armorer Works does not simply change the finish of the gun and label it as "custom". Each gun that leaves AW Custom has been modified with enhanced features that truly improve the comfort, performance and efficiency of the gun as well as cosmetic upgrades that are not generally seen in an out of the box gun. Custom finishes, improved grips, sights and ergonomic modifications as well as improved performance and gas efficiency are hallmarks of the dedication AW Custom puts into providing their clients with the highest quality Airsoft products possible About Armorer Works: While the world around us has moved to less demanding production techniques, AW Custom has stayed true to its original values based on craftsmanship and quality, that is why AW Custom products are able to last a lifetime. We are the keepers of a culture's ancient craft, a symbol of the airsoft gun maker's desire to stay true to tradition. Each stage of the process: from manufacturing to finishing, is a specialized skill that takes time and careful attention.
