AEG Delta Armory GP FREYA R15 Skeleton M-LOK 13" Gen2 — OD — Green

The GP FREYA R15 Skeleton M-LOK 13" Gen2 is an AEG airsoft gun from Delta Armory's GP line, designed for players who want a skeleton-style AR platform with an M-LOK handguard, a 330 mm inner barrel, and an adjustable overall length between 765 and 845 mm. The 2380 g weight reflects a metal-bodied construction and places this airsoft gun firmly in the category of replicas suited to intensive milsim and advanced CQB use.

At the heart of the replica is a V2 gearbox in QSC configuration with an integrated electronic trigger unit (ETU): the T-Dean connector reduces voltage drop compared to conventional connectors, and the buffer stick battery — 11.1 V Li-Po/Li-Ion — sits in the stock without cluttering the handguard. The 14-tooth piston, 8 mm metal bearings, metal piston head, and metal nozzle form an internals package oriented towards durability under sustained use. The hop-up chamber is plastic: a choice that allows quick manual adjustment in the field, though more demanding users may wish to swap it for a metal unit during tuning.

The firing mode selector covers semi-automatic, burst, full-auto, binary, and DMR — a range that suits a variety of field rules, but which requires ETU calibration before first use. This mandatory procedure must be carried out on safe, with the battery connected and the trigger held for five seconds until a double beep is heard. The muzzle thread is 14 mm counter-clockwise, compatible with the vast majority of aftermarket suppressors and muzzle devices available for airsoft. Recommended BBs weigh 0.25–0.28 g, consistent with the stated velocity of approximately 120 m/s.

Key features

• V2 QSC gearbox with integrated ETU: electronic trigger control eliminates mechanical pre-travel and improves semi-automatic response compared to a standard unit.
• T-Dean connector as standard: no adapter required for mid- and high-range batteries, with lower current loss than Mini-Tamiya connectors.
• 13" M-LOK handguard: the rail-free surface reduces weight on the handguard and allows accessories to be mounted only where needed, without extra adapters.
• Five firing modes including binary: lets you adapt the airsoft gun to the most common field regulations without hardware modifications.
• 14 mm counter-clockwise muzzle thread: compatible with the wide aftermarket accessory ecosystem for M4/AR replicas.
• Manually adjustable plastic hop-up chamber: easy to access and adjust in the field, with upgrade options for those seeking long-range precision.
