Delta Armory GP FREYA R15 Skeleton M-LOK 13" Gen2 Airsoft Gun — Black

The GP FREYA R15 Skeleton M-LOK 13" Gen2 is a skeleton-frame AEG produced by Delta Armory, designed for dynamic airsoft shooting and milsim. With a variable length between 765 mm and 845 mm thanks to the folding stock, and a weight of 2380 g, it sits in the compact CQB category with a 330 mm barrel, balanced for use in tight environments without sacrificing a clean trajectory at medium range.

The internal system is built around a V2 gearbox with Quick Spring Change (QSC), allowing spring replacement without disassembling the airsoft gun. The piston has 14 teeth, with a metal piston head, nozzle and spring guide, and 8 mm metal bearings — a combination that handles sustained rates of fire better than mixed-component setups. Muzzle velocity sits at around 118–120 m/s with 0.25–0.28 g BBs, recommended by the manufacturer as the optimum match for the 6.03 mm inner barrel. The connector is a T-Dean, reducing resistive losses compared to standard Tamiya connectors; the airsoft gun requires an 11.1 V Li-Pol or Li-Ion buffer stick battery, not included.

The electronic trigger unit (ETU) adds burst, automatic, binary and DMR modes to semi-automatic selection, but requires calibration before first use: set the selector to SAFE, connect the battery and hold the trigger for five seconds until a double beep is heard. The metal receiver with a M-LOK rail system spanning 33 cm provides mounting surface along almost the entire length of the outer barrel, keeping a slim profile thanks to the skeleton design. The included magazine is a mid-cap holding 120 BBs, with spring-feed that eliminates the noise typical of hi-caps but requires more frequent top-ups during longer sessions.

Key features

• V2 gearbox with QSC: the spring can be swapped without stripping the bolt group, cutting adjustment time between sessions.
• ETU with five firing modes (semi, burst, auto, binary, DMR): mode selection adapts to field rules without any mechanical changes.
• T-Dean connector fitted as standard: directly compatible with the most common high-performance batteries, no adaptor needed.
• Adjustable length from 765 mm to 845 mm: the folding stock reduces bulk during movement and restores the correct shooting length in seconds.
• M-LOK handguard at 33 cm with skeleton profile: extensive customisation options with standard accessories without adding unnecessary weight.
• 14 mm negative muzzle thread: compatible with most suppressors and tracer units available on the European airsoft market.
