Specna Arms Daniel Defense® MK18 SA-P26 Prime™ Kestrel™ ETU Airsoft Carbine with Brushless Motor
The Specna Arms Daniel Defense® MK18 SA-P26 Prime™ Kestrel™ ETU is a premium electric airsoft carbine created for players who want advanced performance, licensed styling and top-tier internal components straight out of the box. Part of the Specna Arms Prime™ Series, this AEG combines the proven Daniel Defense® platform with a reinforced Æther™ Gearbox V2, Magnus™ TDC hop-up chamber, Kestrel™ V2 Basic ETU and a powerful Dark Matter™ 27k brushless motor.
Finished in Chaos Bronze, the SA-P26 Prime™ offers a distinctive tactical look while delivering the reliability expected from a high-end Specna Arms brushless AEG rifle. With a length of approximately 790–880 mm, a weight of 2750 g and a muzzle velocity of around 430 FPS, this carbine is ideal for outdoor fields, milsim events and players who demand strong range, consistency and fast trigger response.
Prime™ Series – High Performance Out of the Box
The Specna Arms Prime™ line is designed for demanding airsoft players who want a rifle that performs at a high level without immediate upgrades. The SA-P26 features a 6.02 mm precision steel inner barrel with a length of 370 mm, paired with the latest Magnus™ TDC rotary hop-up chamber and Helium™ Flat Hop rubber. This combination improves BB stability, range and repeatability, especially when using high-quality BBs.
The factory-installed Dark Matter™ High Speed 27k brushless motor provides fast cycle speed, excellent efficiency and reliable trigger response. Compared to standard brushed motors, the brushless system offers smoother operation, reduced wear and better power management, making this brushless airsoft carbine a strong choice for intensive gameplay.
Kestrel™ V2 Basic ETU by Eshooter
The Kestrel™ V2 Basic ETU gives the rifle advanced electronic control while remaining easy to program directly through trigger pulls. Designed to work with both brushed and brushless motors, this ETU improves the reliability of the replica and protects the internal components against overload, motor issues and battery drain.
