SA M4 URG-I M-LOK 14" (SA-P30 PRIME™ BLDC™ ASTER II) – Black / Green

Specna Arms M4 URG-I M-LOK 14" (SA-P30 PRIME™ BLDC™ ASTER II)

The PRIME™ series assault rifle represents the best, most refined, most upgraded, most advanced and most reliable platform that Specna Arms currently offers. In short, Specna decided to take a perfectly fitted receiver with the highly durable Nano Coating finish, resistant to scratches and wear, and fill it with premium BLDC™ upgrade parts.
It starts with the Dark Matter™ brushless motor housed inside a new QD pistol grip for quick motor access. The rifle also features the completely redesigned ÆTHER gearbox, capable of handling springs up to M140. Inside you will find the Bluetooth-enabled ASTER II ETU with CNC GATE x SA SOLAR™ trigger, CNC 16:1 gears, CNC cylinder and piston heads with CNC nozzle, 8 mm ball bearings on the piston and motor gears and a bushing on the spur gear. Accuracy is provided by the 6.02 mm inner barrel, paired with a Helium Flat-Hop bucking inside the redesigned MAGNUS™ chamber with TDC adjustment system. The package also includes 3 different AEG springs, and thanks to the ESA2 quick spring change system, you can easily adjust performance according to field limits. If you are looking for a versatile airsoft rifle built from premium components with no need for additional upgrades, then the PRIME™ series is the right choice. The package also includes 2 S-MAG mid-cap magazines with a capacity of 125 BBs and a speedloader for easy loading.

Key Features of the Specna Arms M4 PRIME™ BLDC™ Rifle

Gate ASTER II Bluetooth® The ETU processor unit allows detailed trigger adjustment, fire mode setup, active brake tuning and battery protection settings directly from your smartphone.

Durable Receiver with Nano Coating The surface finish increases scratch resistance and gives the rifle an elegant matte appearance even during intensive use.

Dark Matter™ 27-35k Brushless Motor The brushless motor with adjustable RPM delivers higher efficiency, faster trigger response and significantly improved battery life compared to standard motors.

Redesigned ÆTHER™ Gearbox with BLDC™ Upgrade Parts The ÆTHER™ represents one of the most durable gearboxes on the market. The reinforced shell can handle the included Specna Arms M135 spring, and Specna Arms has patented the design (European patent no. 015044865-0001). Inside you will find CNC steel 16:1 gears, 8 mm J-Cage bearings and a reinforced polycarbonate piston with 14 steel teeth combined with a CNC piston head featuring enlarged airflow ports directing air into the double-sealed CNC cylinder head. The setup is housed inside a ribbed stainless steel cylinder that helps dissipate heat during full-auto fire. Air is delivered to the chamber through a CNC nozzle.

MAGNUS™ TDC Hop-Up Chamber The TDC adjustment system provides more precise hop-up tuning, improved shot consistency and better support for heavier BBs.

Warnings

• Some manufacturers produce heavily overrated springs (for example an M130 spring may perform closer to M140-150), which could exceed the declared durability of the gearbox. We strongly recommend using only the included Specna Arms springs. When using springs from other manufacturers, it is recommended to choose M120 springs to avoid potential damage caused by inaccurate spring ratings.
• When installing springs with progressive (uneven) winding, make sure the end with the tighter coil spacing is placed on the spring guide facing outward from the gearbox.
• Never store the rifle with the battery connected.
• Never store the rifle with pre-cocking enabled. Always release the piston forward before storage to prevent spring damage.
