Description
The Specna Arms Prime™ series combines years of Specna Arms’ experience and commitment to developing airsoft guns. The Prime series embodies this progress in one package, offering a high-quality airsoft gun at a cost-effective price. Specna Arms Prime replicas merge the quality of the EDGE™ series with the performance of new internal components, ensuring an excellent out-of-the-box experience for the most demanding players. Traditionally, experienced players would take their new airsoft guns to a tuning shop immediately after purchase, but the Prime series changes that.
The Prime series is equipped with innovative solutions and the latest technologies, such as the brushless Dark Matter™ motor and Specna Arms Aether™ gearbox, making this series one of the most attractive options on the market. Specna Arms Prime changes the airsoft game and its minimum standards, as the Prime lineup is the first in the world to feature brushless motors as standard in electric airsoft guns!
Specna Arms Daniel Defence RIS III 12.5” SA-P28 Prime HAL ETU
The Specna Arms Daniel Defence RIS III 12.5” SA-P28 Prime HAL ETU airsoft gun replicates the AR-15 model equipped with the updated RIS III rail from real firearm manufacturer Daniel Defense®. The SA-P28 Prime is manufactured under an official Daniel Defense® license, allowing the replica to accurately reproduce the original markings. The RIS III rail differs from the traditional Daniel Defense rail in that the RIS-compatible rails on the sides and bottom have been replaced with M-LOK-compatible slots. The M-LOK mounting points allow accessories to be attached directly to the M-LOK slots. The long top rail enables the installation of various optical sights, while the side and bottom rails are ideal for grips or weapon lights. The 12.5″ outer barrel features 14mm CCW threads under the flash hider for mounting a suppressor or tracer unit.
