Delta Armory Freya Series Grandpower Licensed GP R15 Airsoft AEG Rifle w/ Eagle Optical Unit

Model: 7" M-LOK | Color: Black

Designed for aggressive close-quarters gameplay without sacrificing premium build quality, the Delta Armory Freya Series GP R15 7" M-LOK AEG is a compact, high-performance airsoft rifle built to meet the demands of modern players. As part of the Generation 2 FREYA Series, this rifle represents Delta Armory’s “Full Upgrade – No Compromise” philosophy, combining licensed authenticity, advanced electronics, and reinforced internals straight out of the box.

Officially Licensed Grandpower Replica

The GP R15 is fully licensed by Grandpower, the renowned Slovak firearms manufacturer, and features authentic Grandpower trademarks on both sides of the receiver. The billet-style aluminum alloy receiver is precision-machined and finished with deep stamped roll marks and laser etching, delivering a realistic look and feel that closely mirrors the real firearm. Each rifle also includes a unique serial number, reinforcing its premium and collectible nature.

Compact CQB-Focused Design

With its 7-inch CNC aluminum free-float M-LOK handguard, this FREYA model is purpose-built for CQB and tight indoor environments. The short overall length allows for fast target transitions, easy maneuvering through doorways, and excellent weapon control in confined spaces. The handguard is ultra-slim, lightweight, and M-LOK compatible, making it easy to mount lights, grips, or lasers as needed.

Integrated into the handguard are four QD sling loop attachment points, offering exceptional flexibility for sling configurations. Combined with the rifle’s balanced weight distribution, this makes the GP R15 7" an excellent choice for fast-paced, high-mobility gameplay.

Modern External Features

The FREYA GP R15 features a functional bolt stop with mock bolt hold-open, allowing quick and easy access to the hop-up unit without tools. Front and rear folding iron sights come standard, providing reliable backup aiming solutions when running optics.

The updated Delta Stock v.2 offers an adjustable length of pull and a rubberized buttpad for improved comfort and stability while aiming. A metal end plate with ambidextrous sling attachment points ensures durability and supports both left- and right-handed players. The pistol grip v.2 improves ergonomics while offering a more refined and precise motor height adjustment system compared to previous generations.

Eagle Optical Unit – Advanced MOSFET Control

At the core of the FREYA Gen 2 platform is the Eagle Optical Unit, Delta Armory’s advanced opto-magnetic programmable MOSFET system. Pre-installed from the factory, this ETU delivers extremely fast trigger response and allows safe use of 11.1V LiPo batteries. The rifle is wired with a Deans‑T connector, replacing the traditional Tamiya plug for improved electrical efficiency and reliability.
