Delta Armory GP FREYA R15 M-LOK 14" HPA Pulsar D, TITAN II - Green

HPA, That’s What It’s All About

Looking for a universal rifle for year-round gameplay, no matter if it’s scorching 30 °C or freezing cold while others’ AEGs fail? Want a rifle that can transform in seconds from a precise DMR firing single shots at 150 m/s into a CQB drill shooting 40 BBs per second – all while remaining safe for your opponents in the arena? Do you want better accuracy, longer range, and consistent performance regardless of burst length or outdoor temperature? If you’ve answered at least once with "Hell, Yeah!", then this rifle is made for you. Delta Armory brings a new generation of FREYA rifles equipped with the high-end HPA Pulsar D engine (dual solenoid) and the most advanced processor unit, the GATE TITAN II Bluetooth Expert. Everything is carefully assembled and fine-tuned for maximum performance and durability.
To make the system fully operational, you’ll need to purchase a HPA regulator, HPA tank, HPA hose, and a micro HPA battery with a JST connector. To learn more about the pros and cons of HPA systems and what to look out for, check out our article How to Build an HPA Setup.

Delta Armory GP FREYA R15 HPA Series

The GP R15 FREYA is an assault rifle based on the iconic AR-15 (M4) platform, licensed by Grandpower. Of course, it’s a full-metal replica with a modern body design crafted by designers in Slovakia. If you’re a fan of AR15-type HPA rifles and want a unique design that stands out among the usual M4s and MK18s at every game, and prefer to buy a well-assembled, ready-to-play gun that doesn’t require an immediate visit to a tech, then FREYA will truly become your "beloved" AR-15 (Freya is the beautiful goddess from Norse mythology, her name means "Beloved").
A new feature of the GP FREYA R15 HPA line is the Delta Stock v.2, designed for modern ergonomics and shooter comfort. Its angled shape and thick rubber pad don’t interfere with plate carriers and make aiming easier in various shooting positions. The new Delta QRS v.2 grip adds better looks and ergonomics. The entire GP FREYA AR15 boasts a full-metal construction, including the receiver, handguard, outer barrel with 14mm CCW thread, buffer tube, and other external components (excluding stock, grip, and magazine). The GP FREYA R15 M-LOK 14" HPA features a CNC-machined M-LOK handguard measuring 14 inches (355 mm). The rifle includes multiple sling attachment points (QD sockets on the handguard and stock, and standard loops under the buffer tube). Fans of MilSim and realistic replicas will appreciate the Grandpower markings on the receiver.

GATE TITAN II Bluetooth Expert and GATE Pulsar D HPA Engine

GATE has combined the best of both worlds—AEG and HPA—into a single, reliable system. The processor unit TITAN II in Bluetooth EXPERT V2 configuration stands at the top among ETU units for electric airsoft guns. Paired with the PULSAR D HPA engine (Dual Solenoid), it creates the ultimate tool for players seeking complete control over their rifle while enjoying the consistency and reliability of HPA systems.
Through the GATE Control Station app (download here), you can easily adjust trigger sensitivity, firing modes, burst count, and rate of fire. The system also supports DMR mode with delay between shots. The PULSAR D engine ensures reliable performance and consistent BB feeding—no more “mid-cap syndrome.” It’s compatible with standard AEG nozzles, and the 6 mm air hose fits standard fittings.
