Specna Arms Daniel Defense® MK18 SA-P19 Prime™ Kestrel™ ETU Airsoft Carbine with Brushless Motor
The Specna Arms Daniel Defense® MK18 SA-P19 Prime™ Kestrel™ ETU is a premium electric airsoft carbine built for players who want elite out-of-the-box performance, advanced electronics and a realistic licensed platform. Part of the high-end Specna Arms Prime™ Series, this MK18-style AEG combines a durable metal construction with upgraded internal components, a Dark Matter™ brushless motor and the programmable Kestrel™ V2 Basic ETU.
Based on the iconic Daniel Defense® MK18 design, this carbine is ideal for demanding airsoft players who need a compact but powerful rifle for CQB, urban fields, training scenarios and fast-paced outdoor skirmishes. With a length of 780 mm, a weight of 2710 g and a muzzle velocity of approximately 430 FPS, the SA-P19 Prime™ offers a strong balance between manoeuvrability, range and stability.
Prime™ Series Performance – Ready for Advanced Players
The Specna Arms Prime™ line is designed for players who expect a high-performance AEG without immediately investing in tuning. The Æther™ reinforced Gearbox V2, Magnus™ TDC rotary hop-up chamber, Helium™ Flat Hop bucking and 6.02 mm precision steel inner barrel work together to deliver excellent shot consistency, improved BB stability and reliable accuracy.
The included Dark Matter™ High Speed 27k brushless motor provides fast trigger response, efficient power use and smooth cycling. Compared to traditional brushed motors, a brushless motor offers improved durability and better efficiency, making this Specna Arms brushless AEG a strong choice for players who demand rapid semi-auto response and reliable performance during long game days.
Kestrel™ V2 Basic ETU – Smart Fire Control
The factory-installed Kestrel™ V2 Basic ETU by Eshooter gives this replica advanced electronic control directly out of the box. Programmable by trigger pulls, the system works with both brushed and brushless motors and improves reliability by protecting the internal components from overload, battery drain and rotor lock issues.
