The FREYA R15 SKELETON 13" Gen2 Black from Delta Armory is a full-metal, modern skeleton-style AEG designed for out-of-the-box performance and straightforward upgrades. It ships with the opto-magnetic Eagle ETU for ultra-fast trigger response and wide programmability, and a factory tightbore 6.03 mm inner barrel (330 mm) for consistent grouping. This specific example has been further improved with an aftermarket Psionic hop-up bucking for a better air seal and a gearbox upgraded to 8 mm ball bearing bushings for smoother internals and longer service life. Core manufacturer specs and platform details are available from official listings.
