Specna Arms M4 AEG Rifle CORE Series M4 SBR SA-C02 Black

Durability: The M4 SBR replica from Specna Arms' prestigious CORE™ line is a high-quality, versatile choice for both beginner and experienced airsoft players. Its construction boasts durability and lightness with a receiver, stock slide, handguard, battery-housing SF stock, and pistol grip made from fiber-glass reinforced polymer. This material not only minimizes weight, enhancing mobility in dynamic or extended mil-sim games, but also delivers durability superior to both polymer and metal receivers.

ESA™ Quick Spring Change System: Exclusive to this replica is the ESA™ Quick Spring Change System. This game-changing feature facilitates rapid velocity adjustment for the replica to adapt to different field conditions without requiring specific tools or skills. Access to the spring is as straightforward as removing the stock tube, thus eliminating the need for gearbox disassembly.

High Precision: The M4 SBR delivers accuracy and range, courtesy of a precision 6.03mm barrel and a rotary Hop-Up chamber. The precision barrel optimizes BB flight paths in combination with the rotary-type Hop-Up chamber, ensuring more accurate and longer-range shots.
