DELTA ARMORY × GRANDPOWER

FREYA GP R15 // GEN 2

13″ SKELETON M-LOK • EAGLE OPTICAL ETU • FULL-METAL CONSTRUCTION • 16:1 CNC GEARS • 6.03MM PRECISION BARREL

GRANDPOWER LICENSED // FREYA GEN 2 // 13″ SKELETON // EAGLE ETU // FULL UPGRADE – NO COMPROMISE

The FREYA returns for Generation 2—and Delta Armory didn’t simply change the exterior.

They upgraded the platform.

The Delta Armory x Grandpower FREYA Series GP R15 Airsoft AEG Rifle with Eagle Optical MOSFET – 13″ Skeleton M-LOK / Black combines officially licensed Grandpower styling with an aluminum receiver, CNC aluminum handguard, programmable optical electronic trigger system, 16:1 CNC gearing, full-metal-rack piston, CNC compression components, high-torque motor, 6.03mm precision barrel, rotary hop-up, and QRS Gen. 2 architecture.

Delta Armory describes the Gen 2 philosophy simply:

FULL UPGRADE // NO COMPROMISE

And underneath the distinctive Slovak-inspired R15 exterior is an internal package built to justify that name.

GRANDPOWER

SLOVAK DESIGN // OFFICIALLY LICENSED.

The R15 FREYA isn’t designed as another generic M4.

The series is based on the R15 platform from Slovak manufacturer Grandpower, giving the rifle its distinctive receiver geometry and modern exterior architecture.

Delta Armory’s airsoft version is:

FULLY LICENSED BY GRANDPOWER

with authentic Grandpower trademarks displayed on both sides of the receiver.

Deep stamped-style roll marks, laser-etched details, and a unique serial number further separate the FREYA from a conventional unlicensed AR-style AEG.

SKELETON // 13″

THE FREYA FRONT END.

One of the defining visual elements of this model is its:

CNC ALUMINUM SKELETON M-LOK HANDGUARD

The free-float front end uses an ultra-slim profile with extensive machining that gives the 13″ FREYA its unmistakable appearance.

Integrated M-LOK mounting interfaces provide modular attachment positions for appropriately compatible airsoft accessories without requiring permanent rail sections across every surface.

Across the upper assembly is a continuous rail interface, while folding front and rear sights provide a factory mechanical sighting solution.

This longer Skeleton configuration gives the FREYA a distinctly different silhouette from Delta Armory’s shorter R15 variants.

EAGLE

OPTICAL + MAGNETIC ELECTRONIC CONTROL.

Inside the Gen 2 FREYA is Delta Armory’s:

EAGLE OPTO-MAGNETIC ETU

The programmable electronic trigger unit replaces a conventional mechanical trigger-contact arrangement with a more advanced sensor-based control system.

Its listed functionality includes:

ADJUSTABLE TRIGGER SENSITIVITY

ACTIVE BRAKING

BATTERY MONITORING + PROTECTION

and:

PROGRAMMABLE ELECTRONIC CONTROL

The electronic architecture is also designed for use with compatible 11.1V LiPo batteries, with a Deans/T-plug replacing the older-style Tamiya connector.

Always use a battery meeting Delta Armory’s current voltage, connector, dimensional, and capacity recommendations for this specific model.

16:1 CNC

THE GEN 2 DRIVETRAIN.

Behind the electronics is an extensively upgraded mechanical package.

At its core is a:

CNC 16:1 GEARSET

paired with a:

HIGH-TORQUE MOTOR

and:

FULL-METAL-RACK PISTON

This gives the FREYA a performance-oriented drivetrain directly from the factory instead of relying on a collection of immediate aftermarket upgrades.

The gearbox is further supported by bearing architecture and durable internal components throughout the system.

CNC COMPRESSION SET

FACTORY UPGRADED.

Delta Armory continues the upgrade package throughout the compression system.

Factory components include a:

CNC PISTON HEAD

CNC CYLINDER HEAD

CNC NOZZLE

CNC STAINLESS-STEEL CYLINDER

and:

CNC STAINLESS-STEEL SPRING GUIDE

This is one of the biggest differences between the Gen 2 FREYA and a basic mid-range AR AEG.

The upgrades aren’t concentrated in one visible component—they extend through the drivetrain and air system.

6.03MM

PRECISION BARREL + ROTARY HOP.

The air system is completed with a:

6.03MM PRECISION INNER BARREL

paired with a:

ROTARY HOP-UP CHAMBER

The functional bolt-stop system holds the mock bolt open, making access to the hop-up adjustment area more convenient.

A precision inner barrel is only one part of overall AEG consistency. BB quality and weight, hop adjustment, bucking condition, barrel cleanliness, air seal, and gearbox consistency all contribute to actual performance.

QRS GEN. 2

SERVICE-FRIENDLY ARCHITECTURE.

The FREYA also incorporates Delta Armory’s:

QRS GEN. 2 SYSTEM

designed to make appropriate spring servicing more accessible than conventional gearbox designs requiring extensive disassembly.

A QRS motor-access architecture is also incorporated into the platform.

Internal servicing and configuration changes should follow current Delta Armory documentation or be completed by an experienced airsoft technician.

DELTA STOCK V2

REDESIGNED FOR GEN 2.

The rear of the rifle receives Delta Armory’s updated:

DELTA STOCK V2

with adjustable length of pull and a rubberized butt surface.

QD sling interfaces are incorporated into the stock, while a metal receiver end plate provides additional ambidextrous sling attachment points.

Delta Armory also equips the Gen 2 platform with its revised V2 pistol grip, completing the updated exterior furniture package.

EAGLE ETU + TECHNICAL NOTE

The Eagle ETU is an advanced electronic component. Battery selection, initial calibration, programming, internal servicing, and replacement components should follow the documentation supplied for the exact ETU version installed in the rifle.

Do not assume that programming instructions from an older Delta Armory ETU apply to the current Eagle unit.

FREYA GEN 2

GRANDPOWER OUTSIDE // DELTA ARMORY INSIDE.

The Delta Armory x Grandpower FREYA Series GP R15 13″ Skeleton M-LOK Airsoft AEG with Eagle Optical MOSFET combines one of Delta Armory’s most distinctive licensed exteriors with an unusually extensive factory upgrade package.

Its Grandpower-licensed aluminum receiver, CNC Skeleton M-LOK handguard, Eagle optical ETU, 16:1 CNC gears, high-torque motor, full-metal-rack piston, CNC compression components, 6.03mm precision barrel, rotary hop-up, QRS Gen. 2 architecture, and Delta Stock V2 create a rifle built around far more than appearance.

For customers searching for a Delta Armory FREYA Gen 2, Grandpower R15 airsoft rifle, 13 inch M-LOK AEG, Eagle Optical MOSFET airsoft gun, upgraded full-metal M4 AEG, Delta Armory FREYA Canada, or Grandpower licensed airsoft AEG, the 13″ Skeleton represents the performance-focused side of the FREYA family.
