Specna Arms RRA SA-P07 PRIME Aster II ETU BLDC, Half-Tan

The Specna Arms RRA SA-P07 PRIME Aster II ETU BLDC is an M4/AR15-style electric airsoft carbine with a factory-installed brushless motor and Bluetooth-programmable electronic trigger unit. It combines a compact carbine layout with the updated internals of the PRIME series. This makes it a practical choice for players who value adjustable controls and a comprehensive factory specification.

The Half-Tan finish pairs a black metal receiver with tan components. Nano Coating helps the receiver resist surface scratches, while the aluminium KeyMod handguard provides mounting options for accessories. The adjustable stock lets you tailor the length to your shooting stance. A 14 mm CCW muzzle thread accepts compatible airsoft suppressors and tracer units.

The GATE ASTER II Bluetooth ETU lets you configure the rifle through the GATE Control Station app. You can adjust trigger sensitivity and pre-cocking, programme firing modes and review operating data. The unit also provides battery and motor protection features. Pre-cocking can shorten the delay between pulling the trigger and firing, although it increases mechanical wear. Settings should suit the rifle’s configuration and your field’s rules.

The Dark Matter brushless motor drives a reinforced Æther V2 gearbox equipped with 16:1 CNC steel gears, a polymer piston with a full steel tooth rack and aluminium pneumatic components. The bevel and sector gears run on 8 mm J-Cage ball bearings, while the spur gear uses bushings. Inspection openings make it easier to check piston engagement and pre-cocking position during maintenance.

The Magnus TDC hop-up chamber and Helium Flat Hop bucking handle BB trajectory adjustment. They work alongside a precision steel inner barrel with a 6.02 mm bore. The rotary adjustment allows you to fine-tune the hop-up for your chosen BBs. Together, these components provide features that players often add to an AEG through separate upgrades.

The ESA2 quick spring change system allows spring replacement without opening the gearbox or using specialist tools. The included M90 and M135 spare springs provide options for adjusting the rifle’s output. Check muzzle energy with a chronograph after changing the spring. The manufacturer recommends a 7.4 V battery when using an M90 spring or a softer spring.

Alongside the rifle, the package contains two 125-round S-MAG mid-cap magazines, a vertical foregrip, a speedloader, a cleaning rod, a Mini Tamiya-to-Deans adapter and M90 and M135 spare springs. A battery and charger are not included and must be purchased separately.
