The Diamondback DB15 AP300 7″ AEG in black with M-LOK (Body Only) is a compact, high-performance electric airsoft rifle tailored for close-quarters and mid-range engagements. Featuring a full-metal upper receiver and reinforced polymer lower receiver, the DB15 AP300 sports a 7″ M-LOK aluminum handguard that supports a wide range of attachments, including lights, lasers, and grips. An adjustable crane-style stock and ambidextrous controls—such as a reversible fire selector and bolt catch—ensure ergonomic customization for both right- and left-handed shooters. The streamlined pistol-length gas tube and low-profile gas block maintain AR-style compatibility and a sleek profile.

Under the hood, the DB15 AP300 houses a Version 2 gearbox equipped with reinforced gears and a high-torque motor, delivering consistent performance at approximately 330–350 FPS with 0.20 g BBs when paired with a 7.4 V or 11.1 V LiPo battery (not included). The quick-change spring system allows for rapid FPS adjustments to meet field regulations. A precision-polymer hop-up chamber, featuring an adjustable captive wheel, ensures tight groupings and reliable backspin. The integrated MOSFET enhances trigger response and protects internal wiring, while the reinforced piston and metal piston head boost durability during high-rate semi-auto and full-auto fire.

Ergonomic rubberized grips—on both the pistol grip and optional angled foregrip—reduce hand fatigue during extended play. A full-length 20 mm Picatinny top rail accommodates optics and iron sights; removable flip-up sights enable co-witnessing with red-dot or holographic sights. Quick-detach sling mounts on either side of the receiver support varied sling setups. Weighing approximately 2.3 kg (without battery or magazine) and measuring 660 mm overall (stock collapsed), the DB15 AP300 7″ offers a perfect balance of maneuverability and stability for indoor CQB or outdoor field use.
