Pheas Airsoft does an unboxing of the Double Eagle M931A DRP9 airsoft rifle, which he humorously referred to as the "derpy sister" to the DMP9. This airsoft gun has a solid build featuring an all-aluminum monolithic upper receiver, a polymer lower, and full ambidexterity across all controls, including the charging handle, magazine release, and a unique bolt release system.

Technically, the rifle is equipped with a programmable Falcon MOSFET, offering advanced firing modes like three-round burst and a binary trigger, alongside a quick-change spring gearbox. Performance tests showed a high rate of fire, reaching nearly 20 rounds per second on an 11.1V LiPo battery, and an effective range of at least 50 meters. The DRP9 uses proprietary magazines that are compatible with the DMP9, but note that the battery compartment only accommodates shorter, "stubby" form-factor LiPo batteries.
