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 batteries. The weapon’s gearbox comes with upgrades like 8mm ball bearings, and steel 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 enables repeated shots at a stable variation of BBs. With those reinforced internals, the replica comes out of the box ready to be used with an M140 spring. With an ESA™ Quick Spring Change System, you can adapt your replica’s power to your preferences or conditions 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 go to any workshop. The set also comes with an M90 spring which is used to reduce your muzzle velocity with respect to your ranges or activity ensuring your safety.
