Just like the other series, Specna Arms® CORE line is equipped with a quick spring change system. There is no need to take the gearbox out of the replica in order to exchange the spring or adjust the muzzle velocity to the required value. All you have to do is to disassemble the buffer tube by unscrewing just one screw, spin off the pin with the spring guide and exchange the spring.
Use a screwdriver to remove the screw holding together the stockpipe and the receiver; remove the stockpipe.
Use a screwdriver to gently push the spring guide forward. Rotate the spring guide by 45 degrees until you feel the spring's tension.
Pull the spring guide and spring out of the gearbox.
