HPA Airsoft Rifle Delta Armory GP Freya R15 Skeleton 13" — Black

The GP Freya R15 Skeleton 13" is an HPA-powered AR-format airsoft gun designed for players who want full electronic control over the compressed-air engine without giving up the modularity of an M4 platform. With an overall length between 765 and 845 mm and a weight of 2220 g, it comes standard with two separate control units — the Pulsar D and the TITAN II — mounted on a V2 gearbox with a metal nozzle and a 330 mm inner barrel with a 6.03 mm bore.

The HPA system does away with the traditional electric motor: compressed air is fed directly from an external tank via a line at an operating pressure between 60 and 140 PSI, and the muzzle velocity is adjustable between 75 and 195 m/s. The Pulsar D handles regulation across a voltage range of 5–8.6 V DC with a maximum current of 10 A, while the TITAN II — covering 3.75–17 V DC and a maximum current of 30 A — offers advanced fire modes: semi, configurable burst from 2 to 99 BBs, full auto, pre-cocking, AUG mode, sniper delay, binary, and an adjustable rate of fire from 1 to 40 BBs per second. Connectivity is via Bluetooth 5.2 Low Energy, enabling smartphone configuration without opening the gun. The trade-off to be aware of is that HPA requires a complete external setup — tank, regulator, and line — which is not included: compared to a standard AEG the preparation is more involved, but in return you get ballistic consistency and fire-cycle customisation that no traditional electric motor can match.

The receiver is metal with an M-LOK mounting system on the 13" skeleton handguard, which reduces perceived weight and provides attachment points along the full length of the guard. The hop-up is adjustable with a Berserker bucking and a polymer chamber. The included mid-cap magazine holds 120 BBs and requires a speed loader for filling. The manufacturer recommends BBs weighing between 0.28 and 0.32 g to get the best balance between velocity and flight stability. The muzzle thread is 14 mm CCW, compatible with most suppressors and launcher attachments for AR platforms on the market.

Key features

• Two integrated control units (Pulsar D + TITAN II): rate of fire, burst, and pre-cocking are configured via Bluetooth without disassembling the gun.
• Adjustable operating pressure between 60 and 140 PSI lets you tune BB velocity to suit the site rules or event regulations.
• The 13" M-LOK skeleton handguard opens up the full mounting surface without adding unnecessary weight.
• The 6.03 mm inner barrel with Berserker hop-up bucking maintains consistent hop effect even with heavier BBs.
• The 14 mm CCW thread makes the muzzle compatible with the majority of standard accessories for AR airsoft platforms.
