DELTA ARMORY × GRANDPOWER

FREYA GP R15 // GEN 2

10″ M-LOK • OD GREEN • EAGLE OPTICAL ETU • FULL-METAL CONSTRUCTION • CNC UPGRADE PACKAGE

GRANDPOWER LICENSED // FREYA GEN 2 // 10″ M-LOK // OD GREEN // EAGLE ETU // 16:1 CNC GEARS

Compact proportions. Distinctive Slovak-inspired styling. Serious factory internals.

The Delta Armory x Grandpower FREYA Series GP R15 Airsoft AEG Rifle with Eagle Optical MOSFET – 10″ M-LOK / OD Green brings the second-generation FREYA platform into a shorter, highly distinctive configuration.

Built around an officially licensed Grandpower R15-inspired aluminum receiver, this model combines a CNC-machined 10″ M-LOK handguard with OD Green furniture, Delta Stock V2, folding sights, multiple QD sling interfaces, and Delta Armory’s programmable Eagle opto-magnetic electronic trigger system.

Underneath the full-metal exterior is where Gen 2 earns its reputation.

16:1 CNC gears. CNC compression components. High-torque motor. Full-metal-rack piston. Rotary hop-up. 6.03mm precision barrel. QRS Gen. 2.

Delta Armory calls the philosophy:

FULL UPGRADE // NO COMPROMISE.

GRANDPOWER × DELTA ARMORY

MORE THAN ANOTHER AR-STYLE AEG.

The FREYA is based around the distinctive R15 platform from Slovak manufacturer Grandpower.

That heritage gives the rifle its modern receiver geometry and helps separate the FREYA from conventional M4-style AEGs.

The airsoft version is:

OFFICIALLY LICENSED BY GRANDPOWER

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

Deep stamped-style roll marks, laser etching, and an individual serial number add further detail to the exterior.

10″ M-LOK

THE COMPACT FREYA.

This configuration uses a:

CNC-MACHINED ALUMINUM FREE-FLOAT HANDGUARD

with an approximately 10-inch profile.

The handguard incorporates M-LOK-compatible mounting interfaces, keeping the front end streamlined while providing modular attachment positions for appropriately compatible airsoft accessories.

Integrated directly into the handguard are:

FOUR QD ATTACHMENT POINTS

providing multiple locations for compatible QD sling hardware.

The shorter front architecture gives this version noticeably different proportions from the longer 13″ Skeleton FREYA.

OD GREEN

A DISTINCTIVE TWO-TONE BUILD.

Rather than another completely black AR-style rifle, this model introduces:

OD GREEN FURNITURE

against the darker metal receiver and controls.

The colour combination highlights the modern shape of the FREYA while preserving its clean, understated appearance.

For players who like the Grandpower platform but want something visually different from the all-black versions, this is one of the most distinctive configurations in the Gen 2 lineup.

EAGLE ETU

OPTICAL + MAGNETIC CONTROL.

At the centre of the electronic system is Delta Armory’s:

EAGLE OPTO-MAGNETIC ETU

The Eagle replaces conventional mechanical trigger contacts with a modern sensor-based electronic control architecture.

Its listed functions include:

ADJUSTABLE TRIGGER SENSITIVITY

ACTIVE BRAKING

BATTERY MONITORING

LOW-BATTERY PROTECTION

and:

PROGRAMMABLE ELECTRONIC CONTROL

The system is designed around compatible 11.1V LiPo operation, and the rifle uses a modern Deans/T-style connector rather than the older Tamiya format.

Battery dimensions, voltage, connector type, and capacity should always be checked against Delta Armory’s current recommendations for this exact FREYA model.

16:1 CNC

FACTORY PERFORMANCE ARCHITECTURE.

The Eagle electronics are backed by a heavily upgraded mechanical drivetrain.

Inside is a:

CNC 16:1 GEARSET

paired with a:

HIGH-TORQUE MOTOR

and a:

FULL-METAL-RACK PISTON.

This gives the Gen 2 FREYA a much stronger factory foundation than a basic AEG designed around entry-level gearbox components.

CNC COMPRESSION

UPGRADED THROUGHOUT THE SYSTEM.

Delta Armory continues the upgrade package through the compression assembly.

Factory components include:

CNC PISTON HEAD

CNC CYLINDER HEAD

CNC NOZZLE

CNC STAINLESS-STEEL CYLINDER

CNC STAINLESS-STEEL SPRING GUIDE

Rather than relying on one headline upgrade, the FREYA Gen 2 receives improvements across multiple areas of the gearbox.

That complete approach is one of the platform’s defining characteristics.

6.03MM

PRECISION BARREL + ROTARY HOP.

The air system uses a:

6.03MM PRECISION INNER BARREL

paired with a:

ROTARY HOP-UP CHAMBER.

Access is made easier through the functional bolt-stop system, which can hold the mock bolt open while the hop-up area is being accessed.

A 6.03mm barrel should not be considered an automatic guarantee of accuracy or range. Airsoft consistency also depends on BB quality and weight, hop-up adjustment, bucking condition, barrel cleanliness, air seal, and overall gearbox performance.

QRS GEN. 2

DESIGNED WITH SERVICING IN MIND.

The FREYA incorporates Delta Armory’s:

QRS GEN. 2 ARCHITECTURE

designed to simplify appropriate spring access compared with more conventional gearbox designs.

Delta Armory also incorporates its quick-release motor architecture into the platform.

For servicing or internal configuration changes, follow current Delta Armory documentation or use an experienced airsoft technician.

DELTA STOCK V2

UPDATED GEN 2 FURNITURE.

At the rear is Delta Armory’s:

DELTA STOCK V2

with adjustable length of pull and a rubberized butt surface.

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

The updated V2 pistol grip completes the revised Gen 2 furniture package.

EAGLE ETU // TECHNICAL NOTE

Because Eagle ETU hardware and programming can vary between versions, use the documentation supplied with this specific rifle for initial calibration, programming, battery selection, and troubleshooting.

Aftermarket gearbox and electronic components should also be checked for exact FREYA Gen 2 compatibility before installation.

FREYA GEN 2

10″ M-LOK // OD GREEN.
