The Specna Arm Core series (licensed by Rock Rivers Arm) introduces to the market affordable AEGS without any compromise on quality and performance. This new series is fully compatible with LIPO and LIFE battery. The weapon’s gearbox comes with upgrades like 8mm ball bearings, steels gears and is secured with 4 anti-reversal latches. For more precision and accuracy, a rotary Hop-Up with a 6.03 mm diameter tight bore barrel is also integrated which enable repeated shots at a stable variation of BBs. With those reinforced internals, the replica come out of the box ready to be use with a M140 spring. With an ESA™ Quick Spring Change System, you can adapt your replica’s power to your preferences or condition on your gaming sites. Quickly change your main spring. You must only remove the gearbox from the receiver to have access to it without the need to disassemble your gun or going to any workshop. The set also comes with M90 spring which is used to reduce your muzzle velocity in respect to your ranges or activity ensuring your safety. Not to forget one of its plus point. The use of high-quality polymer as one of its main materials does not reduce only its cost but its weight as well compared to normal full metal AEGS hence making it very eligible to beginner airsoft players, indoor gaming and CQB training as well. Easy to use, versatile, durable, crafted with precision. A weapon which is unique and ticks all the boxes.
