Delta Armory MK18 ALPHA Airsoft Rifle — Black

The Delta Armory MK18 ALPHA is a compact AEG airsoft gun in M4 format, designed for those looking for an all-metal AR platform with upgraded internal components straight out of the box. The adjustable length runs from 690 mm to 770 mm thanks to the SF stock, and the 2600 g weight reflects the fully metal construction of the structural external parts.

The receiver, CNC MK18-style rail, outer barrel with 14 mm counter-clockwise threading and buffer tube are all metal: the result is an airsoft gun that shows no wobble or flex between the assemblies even after extended sessions. The Picatinny/RIS rail allows grips, torches or AN/PEQ boxes to be fitted without adapters. The CNC Type A trigger, normally found only in high-end builds or custom setups, is included as standard across the entire ALPHA range: it offers a crisper feel compared to stamped triggers without requiring any aftermarket work.

Internally, the gearbox is a V2 QSC with 14 piston teeth, 7 mm metal bearings and an inner barrel of 265 mm. Muzzle velocity is 115 m/s, suited to the recommended BB weight of 0.25 g to 0.28 g. The SF stock accommodates three-element Crane batteries as well as Stick Buffer and Nunchuk configurations, accessed via the rear plate: this flexibility broadens your battery options, though the best choice depends on the electronics installed and the actual space available in your setup.

Key features

• Full-metal external construction — receiver, CNC MK18 rail, outer barrel and buffer tube — eliminates the structural flex typical of polymer versions.
• Adjustable length from 690 to 770 mm suits operators of different builds and works equally well in indoor and outdoor scenarios.
• The CNC Type A trigger, included as standard, delivers a more defined feel than standard stamped triggers with no additional modifications needed.
• The 14 mm CCW thread on the outer barrel is compatible with the vast majority of aftermarket suppressors and tracer units on the market.
• The V2 QSC gearbox with 7 mm metal bearings and 14 piston teeth provides a solid foundation for future upgrades without replacing the entire assembly.
• The SF stock accepts three-element Crane batteries, Stick Buffer and Nunchuk configurations: broad compatibility reduces dependence on a single battery format.
