Delta Armory M4 Alpha Eagle M-LOK 13" Airsoft AEG — Black

The Delta Armory M4 Alpha Eagle is an AEG airsoft gun in M4/AR15 carbine format, featuring a 13" (330 mm) M-LOK handguard, metal receiver, and an overall length adjustable between 780 mm and 865 mm via the folding stock. Weighing 2580 g and fitted with a 365 mm inner barrel, it is designed for players who want a sturdy, customisable platform for outdoor or mixed-environment airsoft games.

The motor drives a Version 2 QSC gearbox with 14 piston teeth, 7 mm metal bearings, and a metal spring guide: the drivetrain is given adequate structural support for a muzzle velocity of 115 m/s, compatible with BBs weighing 0.25 g to 0.28 g. The onboard processor allows adjustment of the rate of fire or protective functions without any hardware modifications — a direct advantage for players who need to tune the airsoft gun to field limits without stripping the gearbox. The connector is T-Dean, which reduces electrical resistance compared to mini-Tamiya connectors and requires no adapter if the battery is already T-Dean.

The 120-round plastic mid-cap magazine strikes the right balance between capacity and stealth: it has no winding wheel like hi-caps and produces no rattling noise when moving, but once empty it needs to be swapped for a spare rather than topped up on the spot. The stick-type battery is housed in the buffer tube and is not included: a LiPo or NiMH with a T-Dean connector sized to fit the buffer tube must be sourced separately.

Key Features

• Metal receiver: provides structural rigidity and a more solid feel compared to polymer, with a stated weight of 2580 g reflecting the robust build.
• 330 mm M-LOK handguard: allows accessories to be mounted directly onto the rails without additional adapters, keeping a slim profile along the barrel length.
• V2 QSC gearbox with onboard processor: allows firing parameters to be set without hardware intervention, useful at events with restricted rate-of-fire rules.
• T-Dean connector as standard: eliminates the electrical bottleneck of mini-Tamiya connectors and does not require an adapter if the battery already has the same terminal.
• 120-round mid-cap magazine: eliminates the rattling of bouncing BBs typical of hi-caps, at the cost of lower capacity requiring more spare magazines.
• 14 mm counter-clockwise thread: compatible with the vast majority of suppressors and tracer units on the market for the M4 platform.
