Delta Armory GP FREYA R15 Gen2 Series
Delta Armory presents its new generation of AEG rifles based on the iconic AR15 (M4), licensed by the Slovak manufacturer Grandpower, model GP R15 FREYA Generation 2. Generation 2, labeled Full Upgrade – No Compromise, truly delivers top-tier internal parts designed for maximum performance and durability. Simply put, an upgrade without compromise!
This is, of course, a full-metal replica that boasts a modern weapon body design from Slovakia. The brain and heart of the GP FREYA R15 Gen2 rifles is the enhanced optical-magnetic Eagle ETU processor unit by Delta Armory, offering even more features. If you’re an AR15 fan looking for a unique design that stands out from the sea of M4s and MK18s at every event, and you prefer a carefully assembled weapon without needing an immediate service upgrade to stay competitive, then FREYA will truly be your “beloved” AR15. (Freya is a beautiful goddess from Norse mythology, and her name translates to “Beloved”).
Premium External Build
The new GP FREYA R15 series features the Delta Stock v.2, designed with modern ergonomics and shooter comfort in mind. Its angled design and strong rubber buttpad do not obstruct plate carriers and allow for comfortable aiming in different shooting positions. The new Delta QRS v.2 grip not only improves aesthetics but also features a better motor pressure regulation system and, most importantly, quick motor replacement.
The entire GP FREYA AR15 boasts a full-metal construction, including the receiver, handguard, outer barrel with a 14-mm CCW threaded tip, buffer tube, and other external components (except the stock, grip, and magazine).
The GP FREYA R15 M-LOK 10″ Gen2 features a CNC M-LOK handguard measuring 14 inches (355 mm). The rifle includes multiple sling attachment points (QD slots on the handguard and stock, plus classic loops under the buffer tube). Mil-Sim enthusiasts and fans of real firearm replicas will appreciate the Grandpower factory markings on the rifle’s body.
